Hi Ulf,
Thanks for the reply. I applied your patches but I still can't get it to read the SD card
Without the SD card: U-Boot> mmc init 0 mmc: command 55 failed (status: 0x0c100025) mmc: command 1 failed (status: 0x0c100025) No MMC card found
With the SD card: U-Boot> mmc init 0 mmc: command 1 failed (status: 0x0c100025) No MMC card found
I'm not sure what's going on. On Tue, Apr 6, 2010 at 5:57 AM, Ulf Samuelsson ulf.samuelsson@atmel.comwrote:

Hi,
I've been trying to get an SD card working with an at91sam9g45ek-es
board. I
read a couple of threads in the archive and ended up doing this:
I have booted the AT91SAM9G45EKES (Actually the AT91SAM9M10EKES, but it is almost the same) from SD-Card for the last month. The patchset for 2009.11 is available for testing in my private git branch on www.openembedded.org: origin/ulf/linux-2.6.30-20100317
I came to the conclusion that the atmel MCI driver (written for the big endian AVR32) has significant byte sex problems.
BR Ulf Samuelsson.
I applied these patches:
http://lists.denx.de/pipermail/u-boot/2009-August/059595.html http://lists.denx.de/pipermail/u-boot/2009-September/060053.html http://lists.denx.de/pipermail/u-boot/2009-September/060243.html
Added these #define's to include/configs/at91sam9m10g45ek.h:
#define CONFIG_CMD_EXT2 1 #define CONFIG_CMD_FAT 1 #define CONFIG_CMD_MMC 1 #define CONFIG_MMC 1 #define CONFIG_ATMEL_MCI 1
Finally, I added this to the board init function:
#ifdef CONFIG_ATMEL_MCI at91_mci0_hw_init(0, 4); #endif
When I try it out this is what I get: U-Boot> mmc init 0 mmc: clock 150000 too low; setting CLKDIV to 255 mmc: command 1 failed (status: 0x0c100025) No MMC card found
Am I doing something wrong? Any help is appreciated,
Henry
