Keep pressing recovery button and press power button.

Connect a linux OS host wired usb-otg with AIR-030.
In the Host PC, make sure the AIR-030 (NVidia Corp) has detectd.

[ubuntu@linux 11:55:43 ~]$ lsusb

Extract image

$ tar -zxvf air030_image_XXXXXX.tar.gz

$ cd bootloader
$ sudo -s
# source flashcmd.txt

Tools

Test Command

GPIO Expander

Test GPIO high/low
1).Switch to root

ubuntu@localhost:~ sudo -s

2).Commnad : where <GPIO> : GPIO0(GPIO300)~GPIO15(GPIO315) and <LEVEL> : high(1)/low(0) For example, pull up GPIO0 to high.

root@localhost:/home/ubuntu# echo 300 > /sys/class/gpio/export
root@localhost:/home/ubuntu# echo out > /sys/class/gpio/gpio300/direction
root@localhost:/home/ubuntu# echo 1 > /sys/class/gpio/gpio300/value

TPM

(1)產生randon code

root@imx8mprom5722a1:~# tpm2_getrandom --hex 20

(2) 對指定檔案 msg.dat 加密

root@imx8mprom5722a1:~# tpm2_createprimary -C p -c platform_primary.ctx
root@imx8mprom5722a1:~# tpm2_create -C platform_primary.ctx -G rsa2048 -u key.pub -r key.priv
root@imx8mprom5722a1:~# tpm2_load -C platform_primary.ctx -u key.pub -r key.priv -c key.ctx
root@imx8mprom5722a1:~# echo "my test" >msg.dat
root@imx8mprom5722a1:~# tpm2_rsaencrypt -c key.ctx -o msg.enc msg.dat
root@imx8mprom5722a1:~# cat msg.enc
root@imx8mprom5722a1:~# tpm2_rsadecrypt -c key.ctx -o msg.ptext msg.enc
root@imx8mprom5722a1:~# cat msg.ptext 
root@imx8mprom5722a1:~# cat msg.dat

(3) 將資料儲存至 tpm 內存

root@imx8mprom5722a1:~# tpm2_nvdefine -Q 0x1500031 -C o -s 32 -a "ownerread|policywrite|ownerwrite"
root@imx8mprom5722a1:~# echo "write_tpm_adv" >  adv.data
root@imx8mprom5722a1:~# tpm2_nvwrite -Q 0x1500031 -C o -i adv.data
root@imx8mprom5722a1:~# tpm2_nvread -Q 0x1500031 -C o -s 32 -o read.data
root@imx8mprom5722a1:~# cat read.data

(4) 確認已經寫入儲存區域　

root@imx8mprom5722a1:~# tpm2_nvreadpublic > nv.out
root@imx8mprom5722a1:~# cat nv.out

Error

ERROR: Esys_NV_DefineSpace(0x14C) - tpm:error(2.0): NV Index or persistent object already defined
ERROR: Failed to create NV index 0x1500031.

fixed

root@imx8mprom5722a1:~# tpm2_nvundefine 0x1500031

UART

RS232 (COMX_SW1 : OFF-OFF-X-X)

Audio

HDMI output

$ aplay -D hw:0,3 xxx.wav

Line-Out

$ aplay -D hw:1,0 xxx.wav

FAN

Change PWM value ${PWM} from 1 ~ 255.

ubuntu@localhost:~$ sudo -s
root@localhost:/home/ubuntu# echo ${PWM} > /sys/class/hwmon/hwmon3/pwm1

CAN

$ modprobe can
$ modprobe can-dev
$ modprobe mttcan
$ ip link set can0 type can bitrate 500000
$ ip link set can0 up
$ ip link set can1 type can bitrate 500000
$ ip link set can1 up

In other terminal, run below command

$ candump can1

then run

$ cansend can0 123#abcdabcd

Flash Mac

I225 Flash Tool
Copy and extract I225_Flash_Tool.zip in the device.

ubuntu@localhost:~$ unzip I225_Flash_Tool.zip

Chanage the tool execution permission.

<pre>ubuntu@localhost:~$ sudo chmod a+x ./EepromAccessTool

Check All Intel-226 Module in PCI bus, The BDF(bus number/device number/function number) value will be first column.

ubuntu@localhost:~$ lspci
0004:00:00.0 PCI bridge: NVIDIA Corporation Device 229c (rev a1)
0004:01:00.0 PCI bridge: ASMedia Technology Inc. Device 2806 (rev 01)
0004:02:00.0 PCI bridge: ASMedia Technology Inc. Device 2806 (rev 01)

0004:05:00.0 Ethernet controller: Intel Corporation Device 15f2 (rev 03)

Check NIC value with EepromAccessTool tool.

Flash Mac Address To get -nic value and BDF value please using above method.

$ sudo -s
# setpci -s 0004:04:00.0 COMMAND=0007
# ./EepromAccessTool -nic=1 -f=FXVL_15F2_LM_2MB_ARK_1.82_D.bin -mac=D4E5F6123456

The other Intel-I226

#setpci -s 0004:05:00.0 COMMAND=0007 
#./EepromAccessTool -nic=2 -f=FXVL_15F2_LM_2MB_ARK_1.82_D.bin -mac=D4E5F6123457 

Please do cold reboot after flash mac address.

How to check whether the flash proccess is success or not

• lspci command - If it is 0x125f value, it failed.
• ifconfig -a - Check the nerwork interface is available. ex: eth0, eth1 and so on.

Boot On Off

The boot count message will be printed before log-in.

Reset the boot count please remove bootCount.tt.

$ rm bootCount.tt
