Hi,
thanks for your replay,
yes, i know the MVL 2.6.10 kernel support sd mmc card. when i insert the
card, i can find /dev/mmcblk0 and /dev/mmcblk0p0.
i want to know, when i insert card.
why kernel print "devfs_mk_dir: invalid argument."
i think there is something wrong under "devfs_mk_dir("mmc")".
but i don't know why?
