### Copy PFE firmware
Please make sure that you copy the PFE firmware with the right version meta-netmodule-bsp/recipes-kernel/pfe/pfe_<version> to meta-netmodule-bsp/recipes-kernel/pfe/pfe/. You need to copy the class and util firmware files. This is necessary because the firmware is currently only available under NDA.
## Selecting hardware target
The hardware target can be selected by sourcing the machine_select script:
```
source machine_select
9 # Selecting ProCV2.2
9 # Selecting VCU3
```
## Building an image
@ -54,79 +51,3 @@ It can be build with the following commands:
source env.image-ostree
bitbake netmodule-linux-image-dev
```
## Usage
### 1000BaseT1
The PFE driver comes up automatically. However, it does by default rely on autoneg. This doesn't seem to work with the Göpel Media Converter EasyCON. Therefore, a reset is required. Currently pfe0 shares the reset signal with eth0. That's why the following works:
```
brginup.sh enable-pfe
ifconfig eth0 down
ifconfig eth0 up
```
Now the 1000BaseT1 PHY works in default mode.
### Modem
The modem is disabled by default. However, it is possible to enable it with the following command:
```
bringup.sh enable-modem
```
To use adb you have to do the following:
```
echo 0x2c7c >> ~/.android/adb_usb.ini
adb shell
```
### Wifi
Enable the Wifi module (make sure you enable the modem first):
```
bringup.sh enable-wifi
```
### ADCs
Read out the SPI ADCs:
```
bringup.sh read-adc
```
### IMU
To enable the IMU you can call enable-imu.sh:
```
bringup.sh enable-imu.sh
```
To communicate with the imu you can use test-imu.sh:
```
# Read/Write
bringup.sh read-write-imu /dev/spidev1.0 1 2020
# Read
bringup.sh read-write-imu /dev/spidev1.0 1
```
### Secure Element
To enable the secure elelment call enable-secure-element:
```
bringup.sh enable-secure-element
```
There is no helper for the secure element available yet. You can use spidev_test to communicate with it:
```
spidev_test --help
```
### V2X
Enable the V2X and load a firmware (make sure you enable the modem first):
```
bringup.sh enable-v2x <path to fw>
```
### GPIOS
Set gpio:
```
bringup.sh set-gpio <gpio> <value>
```
Get gpio:
```
bringup.sh get-gpio <gpio>
```
