Flash Mac Address
GBE in eeprom
$ sudo ./eeprom $SOC $mac_address
Where SOC
186 : TX2-NX 194 : XavierNX 210 : Nano
Intel I210
$ sudo -s
$ BDF=`lspci | grep 210 | awk '{print $1}'`
$ setpci -s $BDF COMMAND=0007
Get NIC
$./EepromAccessTool
Flash I210 address with mac_address = D4E5F6123456 ( If mac address = D4:E5:F6:12:34:56 )
$ ./EepromAccessTool -nic=<NIC> -f=Dev_Start_I210_Copper_NOMNG_8Mb_A2_3.25_0.03.hex -mac=$mac_address
Cold reboot the device.

WatchDog
root@linux:/home/ubuntu$ sudo -s root@linux:/home/ubuntu# sync; sleep 2; sync; echo c > /proc/sysrq-trigger
TPM
(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

GPIO Expander
Test GPIO high/low
- GPIO0 (228) : gpio-419 (PN.01)
- GPIO1 (118) : gpio-440 (PQ.05)
- GPIO2 (127) : gpio-318 (PCC.01)
- GPIO3 (206) : gpio-443 (PR.00)
- GPIO4 (208) : gpio-437 (PQ.02)
- GPIO5 (211) : gpio-453 (PS.04)
- GPIO6 (212) : gpio-436 (PQ.01)
- GPIO7 (218) : gpio-321 (PCC.04)
1).Switch to root
ubuntu@localhost:~ sudo -s
2).Commnad : where <GPIO> : gpio number and <LEVEL> : high(1)/low(0)
For example, pull up GPIO0 to high.
