21You can select the configuration as follows:
22
23 - make sh7785lcr_config

26This board specific command:
27============================
28
29This board has the following its specific command:
30
31 - sh_g200
32 - write_mac
33
34
351. sh_g200
36
37If we run this command, SH4 can control the G200.
38The default setting is that SH4 cannot control the G200.
39
40
412. write_mac
42
43You can write MAC address to SPI ROM.
44
45 Usage 1) Write MAC address
46
47 write_mac [ETHERC ch0] [ETHERC ch1] [GETHERC ch0] [GETHERC ch1]
48
49 For example)
50 => write_mac 00:00:87:6c:21:80 00:00:87:6c:21:81 00:00:87:6c:21:82 00:00:87:6c:21:83
51 *) We have to input the command as a single line
52 (without carriage return)
53 *) We have to reset after input the command.
54
55 Usage 2) Show current data
56
57 write_mac
58
59 For example)
60 => write_mac
61 ETHERC ch0 = 00:00:87:6c:21:80
62 ETHERC ch1 = 00:00:87:6c:21:81
63 GETHERC ch0 = 00:00:87:6c:21:82
64 GETHERC ch1 = 00:00:87:6c:21:83

67Update SPI ROM:
68============================
69
701. Copy u-boot image to RAM area.
Wolfgang Denk6b62b9a2011-12-19 12:03:40 +0100712. Probe SPI device.
72 => sf probe 0
Nobuhiro Iwamatsuc67ce952011-11-08 15:40:08 +090073 8192 KiB M25P64 at 0:0 is now current device
743. Erase SPI ROM.
Wolfgang Denk6b62b9a2011-12-19 12:03:40 +010075 => sf erase 0 80000
Nobuhiro Iwamatsuc67ce952011-11-08 15:40:08 +0900764. Write u-boot image to SPI ROM.
77 => sf write 0x89000000 0 80000
