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/p
Hi All,
I have an MMC driver for my kit (i.MX21 based cogent board
CSB535FS), which is supplied by Cogent (Kernel version 2.6.16).
The original driver (linux/drivers/mmc/mmc_block.c) uses
mmc_register_driver() method to register the driver but the one
supplied by Cogent uses platform_driver_r
Then something is seriously broken with your kernel. I can only assume that this
is because of some vendor modifications. So I would suggest contacting them or
trying to get a vanilla kernel running.
Hmm. I will try getting the vanilla kernel and putting the
required patches. Or rather see wh
Not likely. It's probably a no-op when you don't have devfs.
CONFIG_MMC_DEBUG is already enabled. This is not printing any debug
statements as such.

Hi,

Then you cannot mount them. What output did you see in dmesg when you inserted
the card?
The dmesg contains only the following when I remove and insert the card.
<6>imx-mmc imx-mmc.0: card removed
<6>imx-mmc imx-mmc.0: card inserted
Also I was
This all looks correct. How about /proc/partitions? And what's in /sys/block?
Both of them show no sign of MMC.

Hi All,
Let's try something a lot less complex than mounting. Try running:
dd if=/dev/mmcblk0 of=/dev/null count=100
Here goes the output(error).
/ # dd if=/dev/mmcblk0 of=/dev/null count=100
dd: can't open '/dev/mmcblk0': No such device or address
The /dev is has the following
Hi,
I was talking about the file system on the card. Usually, you've
got vfat on such a card. How about that?
BTW, You mounted proc on /proc and sysfs on /sys, I hope?
Yes I do have the support for vfat and msdos file system. I have
formatted the card on a Windows system with "FAT" file s
Hi All,
# mount /dev/mmcblk0p0 /mnt/mmc
mount: mounting /dev/mmcblk0p0 on /mnt/mmc failed
I have tried with /dev/mmcblk0p0, mmcblk0p1,etc. But of no use. How
Try to mount mmcblk0 and/or try fdisk and look at the partition
table. dmesg output would also be helpful (after the failed mount).

Hi All,
I am new to linux kernel stuff. I am using Cogent CSB535FS board. I
have configured the kernel to include support for MMC card and also
i.MX MMC driver. When I insert the card, it says :
# imx-mmc imx-mmc.0: card inserted
So, the kernel has identified that MMC has been inserted. I h
