Attention

In device used "sudo" or "sudo su" . Password required. 

ubuntu

Flash Mac Address

First, you need to add a patch to the device tree{ Commit da11ea0d: [LAN] Enable Ethernet Controller I225-LM/I225-V support }

Download I226 tool to Device

I226 Flash Tool

Extract file

$ sudo tar zxvf LAN_I226_DS-015.tar.gz

Flash

The MAC address can only be burned in once

Please make sure mac address and set in : -mac=<XXXXXXXXXXXX> 

$ cd LAN_I226_DS-015/I226_Flash_Tool
$ sudo su
# ./EepromAccessTool
# lspci
# setpci -s 0007:01:00.0 COMMAND=0007
# ./EepromAccessTool -nic=1 -f=FXVL_125C_V_2MB_2.27.bin -mac=XXXXXXXXXXXX

Reboot

Cold reboot the device.

<Receive> In terminal, run below command 

$ sudo su
# modprobe can
# modprobe can-dev
# modprobe mttcan
# ip link set can0 type can bitrate 500000
# ip link set can0 up
# candump can0

<Transmit> In other device terminal, run below command 

$ sudo su
# modprobe can
# modprobe can-dev
# modprobe mttcan
# ip link set can0 type can bitrate 500000
# ip link set can0 up
# cansend can0 123#abcdabcd

WatchDog

$ sudo su
# sync; sleep 2; sync; echo c > /proc/sysrq-trigger

Audio

Line-Out 

$ aplay -D hw:1,0 <WAV file>


TPM

Pre-install TPM-tools 

$ sudo apt install --yes tpm2-tools

(1)產生randon code 

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

RTC

DUT AC on:
1. Power on DUT and boot into OS.
2. Connect a LAN cable from the DUT to DHCP server.
3. Get a dynamic IP from DHCP server.
4. Type cmd to disable ntp service in DUT. 

# sudo timedatectl set-ntp false

5. Synchronize system time and RTC time with NTP server. 

# ntpdate tock.stdtime.gov.tw <===安裝ntpdate方式: $sudo apt-get install ntpdate <enter> 
# hwclock -w

6. Keep the DUT on for 24 hours.
7. Synchronize system time and RTC time with NTP server again and check inaccuracies. 

# ntpdate tock.stdtime.gov.tw && hwclock -s &&ntpdate -u tock.stdtime.gov.tw
