| 18 | configuration for This board: |
| 19 | ============================= |
| 20 | |
| 21 | You can select the configuration as follows: |
| 22 | |
| 23 | - make sh7785lcr_config |
| 24 | |
| 25 | |
| 26 | This board specific command: |
| 27 | ============================ |
| 28 | |
| 29 | This board has the following its specific command: |
| 30 | |
| 31 | - sh_g200 |
| 32 | - write_mac |
| 33 | |
| 34 | |
| 35 | 1. sh_g200 |
| 36 | |
| 37 | If we run this command, SH4 can control the G200. |
| 38 | The default setting is that SH4 cannot control the G200. |
| 39 | |
| 40 | |
| 41 | 2. write_mac |
| 42 | |
| 43 | You 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 |
