Hello,
I am trying to boot the kernel image from SD-CARD (mmc0) in the CM-510
SoM(provided by Compulab) using the u-boot image provided by Compulab:
http://www.compulab.co.il/products/computer-on-modules/cm-a510/#devres
By default, it seems SD-Card is not enabled, so I think I have to
configure right the MPP option.
I have searched over and over in the code sources, I have change some
arrays defined in some files that are related to the MPP (pinmux) but
nothing happens:
./board/marvell/mv_dove/dove_family/boardEnv/mvBoardEnvSpec.h:
* DB-88F6781-BP B0 */
#define DB_88AP510BP_B_MPP0_7 0x00000000
#define DB_88AP510BP_B_MPP8_15 0x00442000
#define DB_88AP510BP_B_MPP16_23 0x32334043 <---
#define DB_88AP510BP_B_MPP24_31 0x11111111
#define DB_88AP510BP_B_MPP32_39 0x11111111

(~((BIT1)|(BIT2)|(BIT5)|(BIT7)|(BIT8)|(BIT10)|(BIT11)|(BIT14)|(BIT15)|(BIT16)|(BIT18)|(BIT19)))
#define DB_88AP510BP_B_OE_HIGH 0x0FFFFFFF
#define DB_88AP510BP_B_OE_VAL_LOW
((BIT1)|(BIT2)|(BIT5)|(BIT7)|(BIT8)|(BIT10)|(BIT11)|(BIT16)|(BIT18)|(BIT19))
#define DB_88AP510BP_B_OE_VAL_HIGH 0x0
./board/marvell/mv_dove/dove_family/boardEnv/mvBoardEnvSpec.c:
MV_BOARD_MPP_INFO db88f6781bpbInfoBoardMppConfigValue[] =
{{{{
DB_88AP510BP_B_MPP0_7,
DB_88AP510BP_B_MPP8_15,
DB_88AP510BP_B_MPP16_23,
DB_88AP510BP_B_MPP40_47 <-------
}}}};
Anyone has faced this problem before? I really appreciate some kind of help.
Best regards,
Gabriel
