Hello All,
We have a custom board based on DM8148, and used eMMC 'MTFC4GMVEA' from micron ( permanently mounted)
It's connected on mmc1 pins on the same lines as SD-card connected on ti8148 evm, with card-detect pin and write protect pin pulled-up high.
It seems, u-boot is able to communicate with this eMMC memory, as u-boot command gives correct info,
#mmcinfo 0
Manufacturer ID: fe
OEM: 14e
Name: MMC04
Tran Speed: 25000000
Rd Block Len: 512
MMC version 4.0
High Capacity: Yes
Capacity: 2199023255552
Bus Width: 4-bit
which is correct, beside the capacity, which i have already figured out in the u-boot code why!
But after starting our customized kernel-2.6.37 ( with modified config based on our board, but all options same in driver-> mmc), we don't see the device node in dev as /dev/mmcblk0. Just an info, we are nfs mounting the root file system provided with the ezsdk, with few files removed from /etc/init.d (like load-hd-firmware, pvr-init, etc)..but udev is there!
I have already checked the mux settings using 'devmem2' utility, they seem OK.
Can somebody point out, what could be wrong and further direction i can look into?
