Here's the command I'm using and the output. I put a debugging statement in sd_init_card() after the for loop (HJS:).
U-Boot> mmc init 0 mmc: clock 150000 too low; setting CLKDIV to 255 HJS: sd_init_card() mmc_acmd for loop finished. ret = -19, resp[0] = 0x6B200020 No MMC card found
The same thing happens if I try mmc init 1.
Thanks,
Henry

Hi Albin,
First of all thanks for the quick reply.
You're welcome.
I tried out what you said about adding #define CONFIG_AT91_MCI1 to the
board
config file but although that did got rid of the mmc: command 1 failed (status: 0x0c100025) error
Great. At least know we know it's actually reading the card :)
it still doesn't see the SD card. After doing some debugging it seems like the statement:
if (aresp[0] & (R1_ILLEGAL_COMMAND | R1_APP_CMD)) != R1_APP_CMD) return -ENODEV;
in mmc_acmd() is being executed, which is causing my problem. Any suggestions?
Not on the top of my head - I have to admit I haven't played with the MMC support for quite some time. Would you mind providing me the exact command you typed and the ouput you got when trying with the "fixed" u-boot? That might help.
