| |
| configuration for This board: |
| ============================= |
| |
| You can choose configuration as follows: |
| |
| - make sh7785lcr_config |
| - make sh7785lcr_32bit_config |
| |
| When you use "make sh7785lcr_config", there is build U-Boot for 29-bit |
| address mode. This mode can use 128MB DDR-SDRAM. |
| |
| When you use "make sh7785lcr_32bit_config", there is build U-Boot for 32-bit |
| extended address mode. This mode can use 384MB DDR-SDRAM. And if you run |
| "pmb" command, this mode can use 512MB DDR-SDRAM. |
| |
| * 32-bit extended address mode PMB mapping * |

| |
| |
| This board specific command: |
| ============================ |
| |
| This board has the following its specific command: |
| |
| - hwtest |
| - printmac |
| - setmac |
| - pmb (sh7785lcr_32bit_config only) |
| |
| |
| 1. hwtest |
| |
| This is self-check command. This command has the following options: |
| |
| - all : test all hardware |
| - pld : output PLD version |
| - led : turn on LEDs |
| - dipsw : test DIP switch |
| - sm107 : output SM107 version |
| - net : check RTL8110 ID |
| - sata : check SiI3512 ID |
| - net : output PCI slot device ID |
| |
| i.e) |
| => hwtest led |
| turn on LEDs 3, 5, 7, 9 |
| turn on LEDs 4, 6, 8, 10 |
| |
| => hwtest net |
| Ethernet OK |
| |
| |
| 2. printmac |
| |
| This command outputs MAC address of this board. |
| |
| i.e) |
| => printmac |
| MAC = 00:00:87:**:**:** |
| |
| |
| 3. setmac |
| |
| This command writes MAC address of this board. |
| |
| i.e) |
| => setmac 00:00:87:**:**:** |
| |
| |
| 4. pmb |
| |
| This command change PMB for DDR-SDRAM all mapping. However you cannot use |
| NOR Flash and USB Host on U-Boot when you run this command. |
| i.e) |
| => pmb |
