Any help is appreciated, Maybe you're not. The at91sam9m10g45 has 2 MMC ports, and the atmel_mci driver only uses one, defined using MMCI_BASE. Now if you look at the end of the third patch: diff --git a/include/asm-arm/arch-at91/memory-map.h b/include/asm-arm/arch-at91/memory-map.h index f605f37..de0aba7 100644 --- a/include/asm-arm/arch-at91/memory-map.h +++ b/include/asm-arm/arch-at91/memory-map.h @@ -32,4 +32,10 @@ #define USART3_BASE (AT91_BASE_SYS + AT91_DBGU) #define SPI0_BASE AT91_BASE_SPI +#ifndef CONFIG_AT91_MCI1 +#define MMCI_BASE AT91_BASE_MCI0 +#else +#define MMCI_BASE AT91_BASE_MCI1 +#endif + So maybe the issue is that it's trying to read on the wrong port. Could you try to add #define CONFIG_AT91_MCI1 in your board config, recompile and see if that works better?
