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.

Test Command

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.

root@localhost:/home/ubuntu# echo 419 > /sys/class/gpio/export
root@localhost:/home/ubuntu# echo out > /sys/class/gpio/PN.01/direction
root@localhost:/home/ubuntu# echo 1 > /sys/class/gpio/PN.01/value
