This sounds like same problem I am having:
Has anyone booted the kernel from SDHC card?
I have 2.6.28 kernel built for Freescale MPC8536E
and booting
from NFS.
I would like to copy the kernel & file system
over to SD
card to eliminate NFS from my Ethernet traffic timing tests.
I have tried 2-4GB SDHC cars and they are
pre-formatted with W95
FAT16 partitions.
I can mount the partition:
mount /dev/mmcblk0p1 /mnt/tmp/
But I can’t write to it.
I tried using fdisk to delete the partition and
make a new linux
partition; tried changing the FAT16 partition to linux
partition.
But I can’t save the changes.
I was able to mount the drive:
mount /dev/mmcblk0 /mnt/tmp/
But I have less than 256MB to write to.
Thanks

No, removing BURST_DMA didn't fix it, it's
something related
to that R4 patch,
not sure what's wrong with it.
Kevin, do you know who's the author of the lpc313x_mmc.c host
driver in R4
patch?

Not sure if my comments will fix it,
I'm facing the exact same problem after switching to the MMC
driver included in
the R4 patch
for the LPC313x kernel from NXP.
I will make some tests to discover what's wrong, if I fix it I
will tell you.
Greetings!

hi Stuart,
its Casper/Kasper whichever... Nolan is my colleague, he
forgot to put my name instead..
Anyway, i do have enough (free) space, i have 1GB SD card
and the Root Filesystem only taken up 250MB. I also mount the
card on an Ubuntu
laptop with SD card reader and i think its OK (i guess!),
since i dont see any
warning and i could mount, umount, copy, delete,etc... But im
not really sure,
because this is not a brand new card, i once use this card for
my old camera.
Is there any tool i can use to fully test my SD cards
integrity or something?
as i am not familiar with any tools for SD card.
I may try Miguel's idea first and if i got the same
problem
then i may purchase a new SD card for further testing...
Thanks.
regards,
Casper

Hi Casper (Nolan?),
You need to worry about these messages. Make sure you have
free space
on the device. Also mount it in another machine (with a
card reader)
and check to see that there is nothing wrong with the device
itself.
