 | |
| Burn U-Boot images to NAND
 | |
| --------------------------
 | |
| 
 | |
| Write the following to the NAND device:
 | |
| 
 | |
|  - spl/u-boot-spl.bin at the offset address 0x00000000
 | |
|  - u-boot.bin         at the offset address 0x00010000
 | |
| 
 | |
| or
 | |
| 
 | |
|  - u-boot-with-spl.bin at the offset address 0x00000000
 | |
| 
 | |
| If a TFTP server is available, the images can be easily updated.
 | |
| Just copy the u-boot-spl.bin and u-boot.bin to the TFTP public directory,
 | |
| and then run the following command at the U-Boot command line:
 | |
| 
 | |
|   => run nandupdate
 | |
| 
 | |
| 
 | |
| Burn U-Boot images to eMMC
 | |
| --------------------------
 | |
| 
 | |
| Write the following to the Boot partition 1 of the eMMC device:
 | |
| 
 | |
|  - spl/u-boot-spl.bin at the offset address 0x00000000
 | |
|  - u-boot.bin         at the offset address 0x00010000
 | |
| 
 | |
| or
 | |
| 
 | |
|  - u-boot-with-spl.bin at the offset address 0x00000000
 | |
| 
 | |
| If a TFTP server is available, the images can be easily updated.
 | |
| Just copy the u-boot-spl.bin and u-boot.bin to the TFTP public directory,
 | |
| and then run the following command at the U-Boot command line:
 | |
| 
 | |
|   => run emmcupdate
 | |
| 
 | |
| 
 | |
| UniPhier specific commands

 | |
| 
 | |
|  - pinmon (enabled by CONFIG_CMD_PINMON)
 | |
|      shows the boot mode pins that has been latched at the power-on reset
 | |
| 
 | |
|  - ddrphy (enabled by CONFIG_CMD_DDRPHY_DUMP)
 | |
|      shows the DDR PHY parameters set by the PHY training
 | |
| 
 | |
|  - ddrmphy (enabled by CONFIG_CMD_DDRMPHY_DUMP)
 | |
|      shows the DDR Multi PHY parameters set by the PHY training
 | |
| 
 | |
| 
 | |

 | |
| 
 | |
| 
 | |
| Micro Support Card
 | |
| ------------------
 | |
| 
 | |
| The recommended bit switch settings are as follows:
 | |
| 
 | |
|  SW2    OFF(1)/ON(0)   Description
 | |
|  ------------------------------------------
 | |
|  bit 1   <----         BKSZ[0]
 | |
|  bit 2   ---->         BKSZ[1]
 | |
|  bit 3   <----         SoC Bus Width 16/32
 | |
|  bit 4   <----         SERIAL_SEL[0]
 | |
|  bit 5   ---->         SERIAL_SEL[1]
 | |
|  bit 6   ---->         BOOTSWAP_EN
 | |
|  bit 7   <----         CS1/CS5
 | |
|  bit 8   <----         SOC_SERIAL_DISABLE
 | |
| 
 | |
|  SW8    OFF(1)/ON(0)   Description
 | |
|  ------------------------------------------
 | |
|  bit 1    <----        CS1_SPLIT
 | |
|  bit 2    <----        CASE9_ON
 | |
|  bit 3    <----        CASE10_ON
 | |
|  bit 4  Don't Care     Reserve
 | |
|  bit 5  Don't Care     Reserve
 | |
|  bit 6  Don't Care     Reserve
 | |
|  bit 7    ---->        BURST_EN
 | |
|  bit 8    ---->        FLASHBUS32_16
 | |
| 
 | |
| The BKSZ[1:0] specifies the address range of memory slot and peripherals
 | |
| as follows:
 | |
| 
 | |
|  BKSZ    Description              RAM slot            Peripherals
 | |
|  --------------------------------------------------------------------
 | |
|  0b00   15MB RAM / 1MB Peri    00000000-00efffff    00f00000-00ffffff
 | |
|  0b01   31MB RAM / 1MB Peri    00000000-01efffff    01f00000-01ffffff
 | |
|  0b10   64MB RAM / 1MB Peri    00000000-03efffff    03f00000-03ffffff
 | |
|  0b11  127MB RAM / 1MB Peri    00000000-07efffff    07f00000-07ffffff
 | |
| 
 | |
| Set BSKZ[1:0] to 0b01 for U-Boot.
 | |
| This mode is the most handy because EA[24] is always supported by the save pin
 | |
| mode of the system bus.  On the other hand, EA[25] is not supported for some
 | |
| newer SoCs.  Even if it is, EA[25] is not connected on most of the boards.
