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.
|

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
|
