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.

JP5.1.0
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.
