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.
