You can always switch between mmc_test and mmc_block by unbinding / binding e.g. # ls -al /sys/bus/mmc/drivers/mmcblk drwxr-xr-x 2 root 0 0 Jan 1 00:00 . drwxr-xr-x 4 root 0 0 Jan 1 00:00 .. --w------- 1 root 0 4096 Jan 1 00:01 bind lrwxrwxrwx 1 root 0 0 Jan 1 00:01 mmc0:0001 -> ../../../../devices/platform/mmci-omap-hs.1/mmc_host/mmc0/mmc0:0001 --w------- 1 root 0 4096 Jan 1 00:01 uevent --w------- 1 root 0 4096 Jan 1 00:01 unbind # echo mmc0:0001 > /sys/bus/mmc/drivers/mmcblk/unbind # echo mmc0:0001 > /sys/bus/mmc/drivers/mmc_test/bind [ 128.221313] mmc_test mmc0:0001: Card claimed for testing. > > I digged further and found that, > 1. mmc_test_probe is invoked only in case of SDIO and not for other hosts. > 2. this is because of from mmc_bus_probe( ), only for SDIO host - > mmc_test_probe () invoked and for other hosts - mmc_blk_probe () invoked. > > > - What can be reason for this? > - Am I missing some patches? > > Also, please let me know, where can I post such mmc related queries.
