Yoshihiro Shimodaada93182009-03-03 15:11:17 +090036configuration for This board:
37=============================
38
39You can choose configuration as follows:
40
41 - make sh7785lcr_config
42 - make sh7785lcr_32bit_config
43
44When you use "make sh7785lcr_config", there is build U-Boot for 29-bit
45address mode. This mode can use 128MB DDR-SDRAM.
46
47When you use "make sh7785lcr_32bit_config", there is build U-Boot for 32-bit
48extended address mode. This mode can use 384MB DDR-SDRAM. And if you run
49"pmb" command, this mode can use 512MB DDR-SDRAM.

791. hwtest
80
81This is self-check command. This command has the following options:
82
83 - all : test all hardware
84 - pld : output PLD version
85 - led : turn on LEDs
86 - dipsw : test DIP switch
87 - sm107 : output SM107 version
88 - net : check RTL8110 ID
89 - sata : check SiI3512 ID
90 - net : output PCI slot device ID
91
92i.e)
93=> hwtest led
94turn on LEDs 3, 5, 7, 9
95turn on LEDs 4, 6, 8, 10
96
97=> hwtest net
