SubjectRe: Fwd: Mounting MMC card
Hi All,

This is referring to my problem - not able to mount MMC card. I
have some output from dmesg when I remove and put the card back (I
have changes the kernel config to include i.MX SPI and disabled the
generic SPI). DOes this give any clue as to why the MMC card is not
appaering in /proc/partions and /sysfs/block ?? Any help will of
great use. The output of dmesg is as follows. I have removed and
inserted the card twice.
