You can change the MAC address in EEPROM by running:
$ /tools/update-mac_smsc75xx.sh
update-mac_smsc75xx.sh {Interface} {Mac Address}
Ex: update-mac_smsc75xx.sh ${ETH_IF} 06 05 04 03 02 01
3.1.9 RS‐232/485/422 Test
To configure the mode of RS232/422/485 transceiver, you have to export GPIO 99 & 100 first.
CRTL_MODE0
(GPOIO 99)
CRTL_MODE1
(GPOIO 100)
For example, you can set GPIO 99 as 1 and GPIO 100 as 0 to enable RS‐232 mode.
[RS‐232]
$ stty -F /dev/ttyMSM1 -echo -onlcr 115200 crtscts
$ cat /dev/ttyMSM1 &
$ echo "Serial Port Test" > /dev/ttyMSM1
[RS‐485/422]
