Hi,
I have plugged Transcend 4GB Class-6 SDHC card to L138 EVM. Card is detected properly. I am getting errors when I tried to create partitions on SD card using fdisk utility. I am using Linux version 2.6.33-rc4.
Please find complete error log below:

root@da850-omapl138-evm:~# fdisk /dev/mmcblk0
The number of cylinders for this disk is set to 123168.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
