Thus disabling. Hmm it might be worth checking that the MMC data lines are muxed correctly. Maybe make sure CONFIG_OMAP_MUX_DEBUG is set in your .config and CONFIG_DEBUG_FS too. Then boot and and mount debugfs with mount -tdebugfs debugfs /sys/kernel/debug. Then you can do: # grep -i mmc1 /sys/kernel/debug/omap_mux/* | grep dat And check the settings. Changing the values could cause data corruption, so use a temporary root file system!
