Intro
|
|
||||||
=====
|
|
||||||
|
|
||||||
Yes, you can program u-boot onto the flash of your Palm Treo 680 so that u-boot
|
|
||||||
(then Linux, Android, ...) runs at power-up. This document describes how, and
|
|
||||||
gives some implementation details on this port of u-boot and describes how the
|
|
||||||
Treo 680 boots from reset.
|
|
||||||
|
|
||||||
But first, I probably don't need to tell you that after doing this, your phone
|
|
||||||
will no longer run PalmOS. You *may* be able to later restore your phone to its
|
|
||||||
original state by creating a backup image of the flash before writing u-boot
|
|
||||||
(details below), but this is not heavily tested and should not be relied upon.
|
|
||||||
There is also the possibility that something may go wrong during the process of
|
|
||||||
programming u-boot, leaving you with a bricked phone. If you follow these
|
|
||||||
instructions carefully this chance will be minimized, but I do not recommend
|
|
||||||
that you program u-boot onto a phone that you can not afford to lose, and
|
|
||||||
certainly not one that contains important data that is not backed up elsewhere.
|
|
||||||
I AM NOT RESPONSIBLE FOR THE LOSS OF YOUR PHONE. DO THIS AT YOUR OWN RISK.
|
|
||||||
Having said that, feel free to send me a note cursing me out if something does
|
|
||||||
go wrong, but please tell me what happened exactly. For that matter, I'd love
|
|
||||||
to hear from you if you succeed.
|
|
||||||
|
|
||||||
|
|
||||||
Details on the SPL
|
|
||||||
==================
|
|
||||||
|
|
||||||
The docg4 features a 2k region at the start of its address space that interfaces
|
|
||||||
to the system bus like a NOR flash. This allows the docg4 to function as a boot
|
|
||||||
ROM. The Treo 680 uses this feature. The contents of this 2k region are
|
|
||||||
write-protected and can not be reprogrammed. Fortunately, the code it contains
|
|
||||||
does what we need to do, at least partially. After some essential hardware
|
|
||||||
initialization (like the SDRAM controller), it runs an IPL (initial program
|
|
||||||
loader) that copies 128K (no more, no less) from flash to a fixed address in
|
|
||||||
SDRAM (0xa1700000) and jumps to it. 128K is too small for u-boot, so we use it
|
|
||||||
to load a u-boot secondary program loader (SPL). But since our SPL only
|
|
||||||
occupies a little over 1k, we can economize on flash usage by having the IPL
|
|
||||||
load a portion of u-boot proper as well. We let the IPL load the first 128k of
|
|
||||||
a concatenated spl + u-boot image, and because the SPL is placed before u-boot
|
|
||||||
proper, the IPL jumps to the SPL, which copies the portion of u-boot that the
|
|
||||||
IPL has already loaded to its correct SDRAM address, and then loads the
|
|
||||||
remainder of u-boot and jumps to it.
|
|
||||||
|
|
||||||
|
|
||||||
The docg4's "reliable mode"
|
|
||||||
===========================
|
|
||||||
|
|
||||||
This is a special mode of operation of the docg4's integrated controller whereby
|
|
||||||
consecutive pairs of 2k regions are used in parallel (in some fashion) to store
|
|
||||||
2k of data. In other words, the normal capacity is halved, but the data
|
|
||||||
integrity is improved. In this mode, the data is read or written from pages in
|
|
||||||
even-numbered 2k regions (regions starting at 0x000, 0x1000, 0x2000, ...). The
|
|
||||||
odd-numbered 2k regions (regions starting at 0x800, 0x1800, 0x2800, ...) are
|
|
||||||
transparently used in parallel. In reliable mode, the odd-numbered 2k regions
|
|
||||||
are not meant to be read or written directly.
|
|
||||||
|
|
||||||
Reliable mode is used by the IPL because there is not enough space in its 2k
|
|
||||||
footprint to implement the BCH ecc algorithm. Data that is read while reliable
|
|
||||||
mode is enabled must have been written in reliable mode, or the read fails.
|
|
||||||
However, data written in reliable mode can also be read in normal mode (just not
|
|
||||||
as reliably), but only from the even-numbered 2k regions; the odd-numbered 2k
|
|
||||||
regions appear to contain junk, and will generate ecc errors. When the IPL and
|
|
||||||
SPL read from flash, the odd-numbered 2k regions are explicitly skipped. The
|
|
||||||
same is true for the flash_u-boot utility when it writes the u-boot image in
|
|
||||||
reliable mode.
|
|
||||||
|
|
||||||
The docg4 Linux driver supports writing in reliable mode (it is enabled by the
|
|
||||||
module parameter), but not reading. However, the u-boot docg4_spl driver does
|
|
||||||
read in reliable mode, in the same fashion as the IPL.
|
|
||||||
|
|
||||||
|
|
||||||
Details on the IPL and its data format
|
|
||||||
======================================
|
|
||||||
|
|
||||||
Starting from block 5 and counting upward, the IPL will search for and load the
|
|
||||||
first two blocks it finds that contain a magic number in the oob of the first
|
|
||||||
page of the block. The contents are loaded to SDRAM starting at address
|
|
||||||
0xa1700000. After two blocks have been loaded, it jumps to 0xa1700000. The
|
|
||||||
number of blocks loaded and the load address in SDRAM are hard-coded; only the
|
|
||||||
flash offset of the blocks can vary at run-time (based on the presence of the
|
|
||||||
magic number).
|
|
||||||
|
|
||||||
In addition to using the docg4's reliable mode, the IPL expects each 512 byte
|
|
||||||
page to be written redundantly in the subsequent page. The hardware is capable
|
|
||||||
of detecting bit errors (but not correcting them), and if a bit error is
|
|
||||||
detected when a page is read, the page contents are discarded and the subsequent
|
|
||||||
page is read.
|
|
||||||
|
|
||||||
Reliable mode reduces the capacity of a block by half, and the redundant pages
|
|
||||||
reduce it by half again. As a result, the normal 256k capacity of a block is
|
|
||||||
reduced to 64k for the purposes of the IPL/SPL.
|
|
||||||
|
|
||||||
For the sake of simplicity and uniformity, the u-boot SPL mimics the operation
|
|
||||||
of the IPL, and expects the image to be stored in the same format.
|
|
||||||
|
|
||||||
|
|
||||||
Instructions on Programming u-boot to flash
|
|
||||||
===========================================
|
|
||||||
|
|
||||||
To program u-boot to your flash, you will need to boot the Linux kernel on your
|
|
||||||
phone using a PalmOS bootloader such as cocoboot. The details of building and
|
|
||||||
running Linux on your Treo (cross-compiling, creating a root filesystem,
|
|
||||||
configuring the kernel, etc) are beyond the scope of this document. The
|
|
||||||
remainder of this document describes in detail how to program u-boot to the
|
|
||||||
flash using Linux running on the Treo.
|
|
||||||
|
|
||||||
|
|
||||||
Hardware Prerequisites
|
|
||||||
======================
|
|
||||||
|
|
||||||
A Palm Treo 680:
|
|
||||||
(dugh)
|
|
||||||
|
|
||||||
A Palm usb cable:
|
|
||||||
You'll need this to establish a usbtty console connection to u-boot from a
|
|
||||||
desktop PC. Currently there is no support in u-boot for the pxa27x keypad
|
|
||||||
(coming soon), so a serial link must be used for the console.
|
|
||||||
These cables are still widely available if you don't already have one.
|
|
||||||
|
|
||||||
A Linux desktop PC.
|
|
||||||
You may be able to use Windows for the u-boot console if you have a usb driver
|
|
||||||
that is compatible with the Linux usbserial driver, but for programming u-boot
|
|
||||||
to flash, you'll really want to use a Linux PC.
|
|
||||||
|
|
||||||
|
|
||||||
Treo-side Software Prerequisites
|
|
||||||
================================
|
|
||||||
|
|
||||||
Linux bootloader for PalmOS:
|
|
||||||
|
|
||||||
Cocoboot is the only one I'm aware of. If you don't already have this, you
|
|
||||||
can download it from
|
|
||||||
https://download.enlightenment.org/misc/Illume/Treo-650/2008-11-13/sdcard-base.tar.gz
|
|
||||||
which is a compressed tar archive of the contents of an sd card containing
|
|
||||||
cocoboot. Use mkdosfs to create a fat16 filesystem on the first primary
|
|
||||||
partition of the card, mount the partition, and extract the tar file to it.
|
|
||||||
You will probably need to edit the cocoboot.conf file to customize the
|
|
||||||
parameters passed to the kernel.
|
|
||||||
|
|
||||||
|
|
||||||
Linux kernel:
|
|
||||||
|
|
||||||
The kernel on the Treo 680 is still a little rough around the edges, and the
|
|
||||||
official kernel frequently breaks on the Treo :( A development kernel
|
|
||||||
specifically for the Treo 680 can be found on github:
|
|
||||||
http://github.com/mike-dunn/linux-treo680
|
|
||||||
The master branch of this tree has been tested on the Treo, and I recommend
|
|
||||||
using this kernel for programming u-boot. As of this writing, there may be a
|
|
||||||
bug in the docg4 nand flash driver that sometimes causes block erasures to
|
|
||||||
fail. This has been fixed in the above tree.
|
|
||||||
|
|
||||||
If you choose to use the official kernel, it must contain the docg4 driver that
|
|
||||||
includes the reliable_mode module parameter. This was a later enhancement to
|
|
||||||
the driver, and was merged to the kernel as of v3.8. Do not try to use an
|
|
||||||
earlier kernel that contains the docg4 driver without support for writing in
|
|
||||||
reliable mode. If you try to program u-boot to flash with the docg4 driver
|
|
||||||
loaded without the reliable_mode parameter enabled, you *will* brick your
|
|
||||||
phone!
|
|
||||||
|
|
||||||
For the purpose of programming u-boot to flash, the following options must be
|
|
||||||
enabled in the Treo kernel's .config:
|
|
||||||
|
|
||||||
CONFIG_MTD=y
|
|
||||||
CONFIG_MTD_CMDLINE_PARTS=y
|
|
||||||
CONFIG_MTD_CHAR=y
|
|
||||||
CONFIG_MTD_NAND_DOCG4=m
|
|
||||||
|
|
||||||
Note that the docg4 nand driver is configured as a module, because we will
|
|
||||||
want to load and unload it with reliable_mode enabled or disabled as needed.
|
|
||||||
|
|
||||||
You will also need to specify mtd partitions on the kernel command line. In
|
|
||||||
the instructions that follow, we will assume that the flash blocks to which
|
|
||||||
u-boot will be programmed are defined by the second partition on the device.
|
|
||||||
The u-boot config file (include/configs/palmtreo680.h) places the u-boot image
|
|
||||||
at the start of block 6 (offset 0x180000), which is the first writable
|
|
||||||
(non-protected) block on the flash (this is also where the PalmOS SPL starts).
|
|
||||||
The u-boot image occupies four blocks, so to create the u-boot partition, pass
|
|
||||||
this command line to the kernel:
|
|
||||||
mtdparts=Msys_Diskonchip_G4:1536k(protected_part)ro,1024k(bootloader_part),-(filesys_part)
|
|
||||||
This will create three partitions:
|
|
||||||
protected_part: the first six blocks, which are read-only
|
|
||||||
bootloader_part: the next four blocks, for the u-boot image
|
|
||||||
filesys_part: the remainder of the device
|
|
||||||
The mtdchar kernel device driver will use device nodes /dev/mtd0, /dev/mtd1,
|
|
||||||
and /dev/mtd2 for these partitions, respectively. Ensure that your root file
|
|
||||||
system at least has /dev/mtd1 if you are not running udev or mdev.
|
|
||||||
|
|
||||||
Userspace Utilities:
|
|
||||||
|
|
||||||
In addition to everything necessary to provide a useful userspace environment
|
|
||||||
(busybox is indispensable, of course), you will need the mtd-utils package on
|
|
||||||
your root filesystem. I use version 1.5.0 of mtd-utils, and I suggest you use
|
|
||||||
this version as well, or at leat a version very close to this one, as
|
|
||||||
mtd-utils has tended to be fluid.
|
|
||||||
|
|
||||||
Note that busybox includes a version of mtd-utils. These are deficient and
|
|
||||||
should not be used. When you run one of these utilities (nanddump, etc),
|
|
||||||
ensure you are invoking the separate executable from mtd-utils, and not the
|
|
||||||
one built into busybox. I recommend that you configure busybox with its
|
|
||||||
mtd-utils disabled to avoid any possibility of confusion.
|
|
||||||
|
|
||||||
You will also need to cross-compile the userspace Linux utility in
|
|
||||||
tools/palmtreo680/flash_u-boot.c, which we will run on the Treo to perform the
|
|
||||||
actual write of the u-boot image to flash. This utility links against libmtd
|
|
||||||
from the mtd-utils package.
|
|
||||||
|
|
||||||
|
|
||||||
Desktop PC-side Software Prerequisites
|
|
||||||
======================================
|
|
||||||
|
|
||||||
Terminal emulator application:
|
|
||||||
minicom, kermit, etc.
|
|
||||||
|
|
||||||
Linux kernel:
|
|
||||||
Compiled with CONFIG_USB_SERIAL enabled. Build this as a module.
|
|
||||||
|
|
||||||
|
|
||||||
Recommended (Not directly related to u-boot)
|
|
||||||
============================================
|
|
||||||
|
|
||||||
Working directly on the Treo's tiny screen and keypad is difficult and
|
|
||||||
error-prone. I recommend that you log into the Linux kernel running on your
|
|
||||||
Treo from your desktop PC using ethernet over usb. The desktop's kernel must be
|
|
||||||
configured with CONFIG_USB_USBNET, CONFIG_USB_NET_CDCETHER, and
|
|
||||||
CONFIG_USB_NET_CDC_SUBSET. The Treo's kernel will need CONFIG_USB_ETH, and its
|
|
||||||
init script will need to start an ssh daemon like dropbear. Note that the usb0
|
|
||||||
network interface will not appear on the desktop PC until the Treo kernel's usb
|
|
||||||
ethernet gadget driver has initialized. You must wait for this to occur (watch
|
|
||||||
the PC's kernel log) before you can assign usb0 an ip address and log in to the
|
|
||||||
Treo. If you also build the Treo's kernel with CONFIG_IP_PNP enabled, you can
|
|
||||||
pass its ip address on the kernel command line, and obviate the need to
|
|
||||||
initialize the network interface in your init script.
|
|
||||||
|
|
||||||
Having the Palm usb cable connected to the host has the added benefit of keeping
|
|
||||||
power supplied to your Treo, reducing the drain on the battery. If something
|
|
||||||
goes wrong while you're programming u-boot to the flash, you will have lots of
|
|
||||||
time to correct it before the battery dies.
|
|
||||||
|
|
||||||
I have encountered a situation where the kernel is sometimes unable to mount a
|
|
||||||
root filesystem on the mmc card due to the mmc controller not initializing in
|
|
||||||
time, (and CONFIG_MMC_UNSAFE_RESUME doesn't seem to help) so I recommend that
|
|
||||||
you build a minimal root filesystem into the kernel using the kernel's initramfs
|
|
||||||
feature (CONFIG_BLK_DEV_INITRD). If you want your root filesystem on the mmc
|
|
||||||
card, your init script can mount and switch_root to the mmc card after a short
|
|
||||||
sleep. But keep in mind that in this case you won't be able to use an mmc card
|
|
||||||
to transfer files between your desktop and the Treo once Linux is running.
|
|
||||||
Another option for transfering files is to mount an nfs filesystem exported by
|
|
||||||
the desktop PC. For greatest convenience, you can export the root filesystem
|
|
||||||
itself from your desktop PC and switch_root to it in your init script. This
|
|
||||||
will work if your initramfs init script contains a loop that waits for you to
|
|
||||||
initialize the usb0 network interface on the desktop PC; e.g., loop while a ping
|
|
||||||
to the desktop PC returns an error. After the loop exits, do the nfs mount and
|
|
||||||
call switch_root. (You can not use the kernel nfsroot feature because the
|
|
||||||
network will not be up when the kernel expects it to be; i.e., not until you
|
|
||||||
configure the usb0 interface on the desktop.) Use the nfs 'nolock' option when
|
|
||||||
mounting to avoid the need to run a portmapper like rpcbind.
|
|
||||||
|
|
||||||
|
|
||||||
Preliminaries
|
|
||||||
=============
|
|
||||||
|
|
||||||
Once Linux is running on your Treo, you may want to perform a few sanity checks
|
|
||||||
before programming u-boot. These checks will verify my assumptions regarding
|
|
||||||
all the Treo 680s out there, and also ensure that the flash and mtd-utils are
|
|
||||||
working correctly. If you are impatient and reckless, you may skip this
|
|
||||||
section, but see disclaimer at the top of this file!
|
|
||||||
|
|
||||||
Load the docg4 driver:
|
|
||||||
|
|
||||||
$ modprobe docg4 ignore_badblocks=1 reliable_mode=1
|
|
||||||
|
|
||||||
We tell the driver to use the docg4's "reliable mode" when writing because this
|
|
||||||
is the format required by the IPL, which runs from power-up and loads the first
|
|
||||||
portion of u-boot. We must ignore bad blocks because linux mtd uses out-of-band
|
|
||||||
(oob) bytes to mark bad blocks, which will cause the blocks written by PalmOS to
|
|
||||||
be misidentified as "bad" by libmtd.
|
|
||||||
|
|
||||||
Check the kernel log to ensure that all's well:
|
|
||||||
|
|
||||||
$ dmesg | tail
|
|
||||||
<... snip ...>
|
|
||||||
docg4 docg4: NAND device: 128MiB Diskonchip G4 detected

|
||||||

||||||

Ensure that the partition boundaries are as shown. (If no partitions are shown,
|
|
||||||
did you remember to pass them to the kernel on the command line?) We will write
|
|
||||||
u-boot to bootloader_part, which starts at offset 0x180000 (block 6) and spans 4
|
|
||||||
256k blocks. This partition is accessed through the device node /dev/mtd1.
|
|
||||||
|
|
||||||
The docg4 contains a read-only table that identifies blocks that were marked as
|
|
||||||
bad at the factory. This table is in the page at offset 0x2000, which is within
|
|
||||||
the partition protected_part (/dev/mtd0). There is a slight chance that one or
|
|
||||||
more of the four blocks that we will use for u-boot is listed in the table, so
|
|
||||||
use nanddump to inspect the table to see if this is the case:
|
|
||||||
|
|
||||||
$ nanddump -p -l 512 -s 0x2000 -o /dev/mtd0
|
|
||||||
ECC failed: 0
|
|
||||||
ECC corrected: 0
|
|
||||||
Number of bad blocks: 0
|
|
||||||
Number of bbt blocks: 0
|
|
||||||
Block size 262144, page size 512, OOB size 16
|
|
||||||
Dumping data starting at 0x00002000 and ending at 0x00002200...
|
|
||||||
0x00002000: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff
|
|
||||||
<... snip ...>
|
|
||||||
|
|
||||||
The format of the table is simple: one bit per block, with block numbers
|
|
||||||
increasing from left to right, starting with block 0 as the most significant bit
|
|
||||||
of the first byte. A bit will be clear if the corresponding block is bad. We
|
|
||||||
want to use blocks 6 throgh 9, so both of the two least significant bits of the
|
|
||||||
first byte must be set, as must the two most significant bits of the second
|
|
||||||
byte. If this is not true in your case (you are very unlucky), you should use
|
|
||||||
the first contiguous set of four good blocks after block 6, and adjust the
|
|
||||||
partition boundaries accordingly. You will also have to change the value of
|
|
||||||
CONFIG_SYS_NAND_U_BOOT_OFFS in include/configs/palmtreo680.h and recompile
|
|
||||||
u-boot. Because the two blocks loaded by the IPL do not have to be contiguous,
|
|
||||||
but our SPL expects them to be, you will need to erase any good blocks that are
|
|
||||||
at an offset prior to CONFIG_SYS_NAND_U_BOOT_OFFS, so that the IPL does not find
|
|
||||||
the magic number in oob and load it. Once you have done all this, the
|
|
||||||
instructions in this file still apply, except that the instructions below for
|
|
||||||
restoring the original PalmOS block contents may need to be modified.
|
|
||||||
|
|
||||||
Next, use nanddump to verify that the PalmOS SPL is where we expect it to be.
|
|
||||||
The SPL can be identified by a magic number in the oob bytes of the first page
|
|
||||||
of each of the two blocks containing the SPL image. Pages are 512 bytes in
|
|
||||||
size, so to dump the first page, plus the oob:
|
|
||||||
|
|
||||||
$ nanddump -p -l 512 -s 0 -o /dev/mtd1
|
|
||||||
ECC failed: 0
|
|
||||||

|
|

|
|
||||||
|
|
||||||
Verify that the first seven bytes of oob data match those in the above line.
|
|
||||||
(This is ASCII "BIPO000".)
|
|
||||||
|
|
||||||
Do the same for the next block:
|
|
||||||
$ nanddump -p -l 512 -s 0x40000 -o /dev/mtd1
|
|
||||||
|
|
||||||
The first seven oob bytes in last line should read:
|
|
||||||
|
|
||||||
OOB Data: 42 49 50 4f 30 30 31 81 db 8e 8f 46 07 9b 59 ff
|
|
||||||
|
|
||||||
(This is ASCII "BIPO001".)
|
|
||||||
|
|
||||||
For additional assurance, verify that the next block does *not* contain SPL
|
|
||||||
data.
|
|
||||||
|
|
||||||
$ nanddump -p -l 512 -s 0x80000 -o /dev/mtd1
|
|
||||||
|
|
||||||
It doesn't matter what the oob contains, as long as the first four bytes are
|
|
||||||
*not* ASCII "BIPO". PalmOS should only be using two blocks for the SPL
|
|
||||||
(although we will need four for u-boot).
|
|
||||||
|
|
||||||
If you want, you can back up the contents of bootloader_part to a file. You may
|
|
||||||
be able to restore it later, if desired (see "Restoring PalmOS" below).
|
|
||||||
|
|
||||||
$ nanddump -l 0x100000 -s 0 -o -f bootloader_part.orig /dev/mtd1
|
|
||||||
|
|
||||||
nanddump will spew voluminous warnings about uncorrectable ecc errors. This is
|
|
||||||
a consequence of reading pages that were written in reliable mode, and is
|
|
||||||
expected (these should all occur on pages in odd-numbered 2k regions; i.e.,
|
|
||||||
0x800, 0xa00, 0xc00, 0xe00, 0x1800, 0x1a00, ...). The size of the file
|
|
||||||
bootloader_part.orig should be 1081344, which is 2048 pages, each of size 512
|
|
||||||
plus 16 oob bytes. If you are using initramfs for the root filesystem, don't
|
|
||||||
forget to copy the file to permanent storage, such as an mmc card.
|
|
||||||
|
|
||||||
If all of the above went well, you can now program u-boot.
|
|
||||||
|
|
||||||
|
|
||||||
Programming u-boot
|
|
||||||
==================
|
|
||||||
|
|
||||||
Our u-boot includes a small SPL that must be prepended to u-boot proper. From
|
|
||||||
the base u-boot source directory on your desktop PC:
|
|
||||||
|
|
||||||
$ cat spl/u-boot-spl.bin u-boot.bin > u-boot-concat.bin
|
|
||||||
|
|
||||||
cd to the tools/palmtreo680/ directory, and cross-compile flash_u-boot.c for the
|
|
||||||
Treo:
|
|
||||||
|
|
||||||
$(CC) -o flash_u-boot $(CFLAGS) $(INCLUDEPATH) $(LIBPATH) flash_u-boot.c -lmtd
|
|
||||||
|
|
||||||
Substitute variable values from your cross-compilation environment as
|
|
||||||
appropriate. Note that it links to libmtd from mtd-utils, and this must be
|
|
||||||
included in $(LIBPATH) and $(INCLUDEPATH).
|
|
||||||
|
|
||||||
Transfer u-boot-concat.bin and the compiled flash_u-boot utility to the Treo's
|
|
||||||
root filesystem. On the Treo, cd to the directory where these files were
|
|
||||||
placed.
|
|
||||||
|
|
||||||
Load the docg4 driver if you have not already done so.
|
|
||||||
|
|
||||||
$ modprobe docg4 ignore_badblocks=1 reliable_mode=1
|
|
||||||
|
|
||||||
Erase the blocks to which we will write u-boot:
|
|
||||||
|
|
||||||
$ flash_erase /dev/mtd1 0x00 4
|
|
||||||
|
|
||||||
If no errors are reported, write u-boot to the flash:
|
|
||||||
|
|
||||||
$ ./flash_u-boot u-boot-concat.bin /dev/mtd1
|
|
||||||
|
|
||||||
You can use nanddump (see above) to verify that the data was written. This
|
|
||||||
time, "BIPO" should be seen in the first four oob bytes of the first page of all
|
|
||||||
four blocks in /dev/mtd1; i.e., at offsets 0x00000, 0x40000, 0x80000, 0xc0000.
|
|
||||||
|
|
||||||
Shutdown linux, remove and re-insert the battery, hold your breath...
|
|
||||||
|
|
||||||
|
|
||||||
Enjoying u-boot
|
|
||||||
===============
|
|
||||||
|
|
||||||
After you insert the battery, the u-boot splash screen should appear on the lcd
|
|
||||||
after a few seconds. With the usb cable connecting the Treo to your PC, in the
|
|
||||||
kernel log of your PC you should see
|
|
||||||
|
|
||||||
<6>usb 3-1: New USB device found, idVendor=0525, idProduct=a4a6
|
|
||||||
<6>usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
|
|
||||||
<6>usb 3-1: Product: U-Boot 2013.01-00167-gd62ef56-dirty
|
|
||||||
<6>usb 3-1: Manufacturer: Das U-Boot
|
|
||||||
|
|
||||||
Load the usbserial module on your desktop PC:
|
|
||||||
|
|
||||||
$ modprobe usbserial vendor=0x0525 product=0xa4a6
|
|
||||||
|
|
||||||
and run your favorite terminal emulation utility (minicom, kermit, etc) with the
|
|
||||||
serial device set to /dev/ttyUSB0 (assuming this is your only usb serial
|
|
||||||
device). You should be at the u-boot console (type 'help').
|
|
||||||
|
|
||||||
There is not much that is unique about using u-boot on the palm treo 680.
|
|
||||||
Kernels can be loaded from mmc, flash, and from the desktop PC via kermit. You
|
|
||||||
can expand the size of the second partition on the flash to contain a kernel, or
|
|
||||||
else put the kernel(s) in their own partition.
|
|
||||||
|
|
||||||
Nand commands work as expected, with the excepton that blocks not written by the
|
|
||||||
linux mtd subsystem may be misidentified by the u-boot docg4 driver as "bad" if
|
|
||||||
they contain data in the oob bytes. This will be the case for the blocks
|
|
||||||
containing the u-boot image, for example. To work around this, use 'nand scrub'
|
|
||||||
instead of 'nand erase' to erase these blocks, and 'nand read.raw' to read them
|
|
||||||
to memory. (It would be useful if u-boot's nand commands provided a way to
|
|
||||||
explicitly ignore "bad" blocks, because read.raw does not perform ecc.) The
|
|
||||||
'nand dump' command will read these "bad" blocks, however.
|
|
||||||
|
|
||||||
Currently u-boot itself can only be programmed to flash from Linux; there is no
|
|
||||||
support for reliable mode in u-boot's docg4 flash driver. This should be
|
|
||||||
corrected soon.
|
|
||||||
|
|
||||||
|
|
||||||
Customizing
|
|
||||||
===========
|
|
||||||
|
|
||||||
If you change u-boot's configuration significantly (adding or removing
|
|
||||||
features), you may have to adjust the value of CONFIG_SYS_NAND_U_BOOT_SIZE.
|
|
||||||
This is the size of the concatenated spl + u-boot image, and tells the SPL how
|
|
||||||
many flash blocks it needs to load. It will be rounded up to the next 64k
|
|
||||||
boundary (the spl flash block capacity), so it does not have to be exact, but
|
|
||||||
you must ensure that it is not less than the actual image size. If it is larger
|
|
||||||
than the image, blocks may be needlessly loaded, but if too small, u-boot may
|
|
||||||
only be partially loaded, resulting in a boot failure (bricked phone), so better
|
|
||||||
to be too large. The flash_u-boot utility will work with any size image and
|
|
||||||
write the required number of blocks, provided that the partition is large
|
|
||||||
enough.
|
|
||||||
|
|
||||||
As the first writable block on the device, block 6 seems to make the most sense
|
|
||||||
as the flash offset for writing u-boot (and this is where PalmOS places its
|
|
||||||
SPL). But you can place it elsewhere if you like. If you do, you need to
|
|
||||||
adjust CONFIG_SYS_NAND_U_BOOT_OFFS accordingly, and you must ensure that blocks
|
|
||||||
preceeding the ones containing u-boot do *not* have the magic number in oob (the
|
|
||||||
IPL looks for this). In other words, make sure that any blocks that previously
|
|
||||||
contained the u-boot image or PalmOS SPL are erased (and optionally written with
|
|
||||||
something else) so that the IPL does not load it. Also make sure that the new
|
|
||||||
u-boot starting offset is at the start of a flash partition (check the kernel
|
|
||||||
log after loading the docg4 driver), and pass the corresponding mtd device file
|
|
||||||
to the flash_u-boot utility.
|
|
||||||
|
|
||||||
The u-boot built-in default environment is used because a writable environment
|
|
||||||
in flash did not seem worth the cost of a 256k flash block. But adding this
|
|
||||||
should be straightforward.
|
|
||||||
|
|
||||||
|
|
||||||
Restoring PalmOS
|
|
||||||
================
|
|
||||||
|
|
||||||
If you backed up the contents of bootloader_part flash partition earlier, you
|
|
||||||
should be able to restore it with the shell script shown below. The first two
|
|
||||||
blocks of data contain the PalmOS SPL and were written in reliable mode, whereas
|
|
||||||
the next two blocks were written in normal mode, so the script has to load and
|
|
||||||
unload the docg4 driver. Make sure that the mtd-utils nandwrite and flash_erase
|
|
||||||
are in your path (and are not those from busybox). Also double-check that the
|
|
||||||
backup image file bootloader_part.orig is exactly 1081344 bytes in length. If
|
|
||||||
not, it was not backed up correctly. Run the script as:
|
|
||||||
|
|
||||||
./restore_bootpart bootloader_part.orig /dev/mtd1
|
|
||||||
|
|
||||||
The script will take a minute or so to run. When it finishes, you may want to
|
|
||||||
verify with nanddump that the data looks correct before you cycle power, because
|
|
||||||
if the backup or restore failed, your phone will be bricked. Note that as a
|
|
||||||
consequence of reliable mode, the odd-numbered 2k regions in the first two
|
|
||||||
blocks will not exactly match the contents of the backup file, (so unfortunately
|
|
||||||
we can't simply dump the flash contents to a file and do a binary diff with the
|
|
||||||
original back-up image to verify that it was restored correctly). Also,
|
|
||||||
nanddump will report uncorrectable ecc errors when it reads those regions.
