$ cd LAN_I226_AIR-021/I226_Flash_Tool
$ sudo su
# ./EepromAccessTool
# lspci
# setpci -s 0009:01:00.0 COMMAND=0007
# ./EepromAccessTool -nic=1 -f=FXVL_125B_LM_2MB_2.23.bin -mac=XXXXXXXXXXXX

Power off and restart

Cold reboot the device.

Bootloader Version

Check device boot up in debugport log

Tools

Test Command

JP6.2

HDMI

Set on debug port

$ export DISPLAY=:0
$ xrandr

Image resolution : Full HD 1920 x 1080 pixels

$ xrandr -d :0 --output HDMI-0 --mode 1920x1080 -r 60.00

Image resolution : 4K 3840 x 2160 pixels

$ xrandr -d :0 --output HDMI-0 --mode 3840x2160 -r 60.00

TPM

Pre-install TPM-tools

$ sudo apt install --yes tpm2-tools

(1)產生randon code

$ sudo su

root@linux:/home/ubuntu# tpm2_getrandom --hex 20

(2) 對指定檔案 msg.dat 加密

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

(3) 將資料儲存至 tpm 內存

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

(4) 確認已經寫入儲存區域　

root@linux:/home/ubuntu# tpm2_nvreadpublic > nv.out
root@linux:/home/ubuntu# 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@linux:/home/ubuntu# tpm2_nvundefine 0x1500031
