Hello. I'm attempting to use the AT91 SD/MMC patches with my AT91SAM9G45-EK-ES devkit to boot a Linux kernel off of an SD card.
Starting with 2009.08, I've applied: http://lists.denx.de/pipermail/u-boot/2009-August/059456.html http://lists.denx.de/pipermail/u-boot/2009-September/060053.html http://lists.denx.de/pipermail/u-boot/2009-September/060243.html
Then I added: #ifdef CONFIG_ATMEL_MCI int cpu_mmc_init(bd_t *bis) { atmel_mci_init(bis); } #endif to the end of cpu/arm926ejs/at91/cpu.c per the patch at: http://lists.denx.de/pipermail/u-boot/2009-August/059457.html and things seem to be showing up on boot. "MMC: ATMEL MCI: 0"
In an effort to enable the SD card functionality I added the following to include/configs/at91sam9m10g45ek.h: /* SD Card */ #define CONFIG_CMD_EXT2 1 #define CONFIG_CMD_MMC 1 #define CONFIG_MMC 1 #define CONFIG_GENERIC_MMC 1 #define CONFIG_ATMEL_MCI 1
However, once I 'mmc init' and try 'ext2ls mmc 0' all I get is: ** Bad partition - mmc 0:1 **
After adding some debugging information it seemed as though get_partition_info was failing, and print_part failed with: ## Unknown partition table
Per a suggestion from the IRC channel, I verified that I have an MBR on the SD card, instead of just a VBR.
Thanks, Dan
