SD/MMC on PB-ARM926EJ-S linux 2.6.12
Greetings!
This is regarding my post on SD/MMC on the
PB-ARM926EJ-S:
http://www.spinics.net/lists/arm-kernel/msg28535.html
I would like to know if anyone is using the SD/MMC on
this versatile PB-ARM926EJ-S board with linux 2.6.12.
I have enabled the options here in the kernel .config:
[*] MMC Support
[ ] MMC debugging
[*] MMC block device driver
[*] ARM AMBA Multimeda Card Interface support
[ ] Winbond W83L51xD SD/MMC Card Interface support
The mmc driver gets loaded as seen in the output
mentioned in the above link. The FPGAs that get mapped
are, fpga:5 and fpga:a, fpga:b. In /proc/devices I see
254 registered with mmc. There is /dev/mmc already in
base.cramfs filesystem provided by ARM, but, do we
need to mount it?
I have a Sandisk 256 MB CF which I place in the MMC
slot, but, I don't see any detection or relevant
output in dmesg. There is a mmc0, mmc1 displayed in
dmesg with address, irq details. Is this relevant?
Do the above mentioned drivers compiled in the kernel
sufficient to use the SD/MMC interface? Or do we have
to write our own drivers?
Any help in this regard is appreciated.
Thanks,
K Shakthi
