2008-01-24 06:13:08 MMC/SD broken?
Miquel Soler i Mir (SPAIN)
Message: 50082 Hello,
My name is Miquel Soler, I'm working with CM-BF537E and eval-board from bluetechnix.
The kernel is: Linux version 2.6.19-3-ADI-2007R1.1-SVN
I'm working with MMC and SD cards to store the program and test it. I don't like to lose all the data in reset.
The MMC and SD are working properly, I test diferents types and makers (SanDisk, Kingston, Transcend).
The problem is that 2 cards were broken after 60 day of working.
The wroked cards were:
1) MMC + plus of 1GB from Kingston
2) SD of 1GB from SanDisk
With these cards I can work with fdisk without problem, but when I check the file system or mount the cards, the system tell me this:
end_request: I/O error, dev spi_mmc,sector 304872
end_request: I/O error, dev spi_mmc,sector 304880
end_request: I/O error, dev spi_mmc,sector 304888
end_request: I/O error, dev spi_mmc,sector 304896
or
spi_mmc: end_request: I/O error, dev spi_mmc, sector 0
buffer I/O error on device spi_mmc, logic block 0
I test these cards in USB card reader and they were working fine; then, I clean and fill up the card without problem.
Can somebody help me with this problem?
Thanks
Miquel Soler i Mir

Message: 50108 It may be better to try to understand why the card was broken on Linux - it is pretty hard to understand after it has been fixed somewhere else.
Did you try fsck.msdos or fsck.vfat?

Message: 50109 I'm sorry for the incomplete information
I'm using EXT3 as a file system in all cards.
to create the file system:
mke2fs -j -c -L SD#1 /dev/mmc1
to check the file system:
e2fsck -p /dev/mmc1
to mount the card:
mount -t ext3 -o async /dev/mmc1 /mnt/mmc1
I don't understand why the cards are not working with uClinux and work with the Host?
Thanks.

Message: 50236 Hello,
I have the same problem, when I use the MMC card and spi_adc.
if I don't use spi_adc everything works. I don't know why...
