28This board has the following its specific command:
29
30 - write_mac
31
32
331. write_mac
34
35You can write MAC address to SPI ROM.
36
37 Usage 1) Write MAC address
38
39 write_mac [GETHERC ch0] [GETHERC ch1]
40
41 For example)
42 => write_mac 74:90:50:00:33:9e 74:90:50:00:33:9f
43 *) We have to input the command as a single line
44 (without carriage return)

49 write_mac
50
51 For example)
52 => write_mac
53 GETHERC ch0 = 74:90:50:00:33:9e
54 GETHERC ch1 = 74:90:50:00:33:9f
