Also at uboot , its able to detect the 4 partitions.

Scanning mmc 0:1...

It looks like that image in not correctly installed on your SD card.

Is there problem for booting from this SD card on your board?

Use "flex-installer" for preparing SD card.

The following command also can be used for writing image file to SD card on your PC:

sudo dd if=firmware_ls1046ardb_uboot_sdboot.img of=/dev/sdb bs=512 seek=8

Booting with tiny linux with SD card is okay. But after that when i give the command fdisk -l to see the memory, am not able to see the mmcblk0.

Attached file shows message log for LSDK 2004 and the "fdisk -l" command.

It looks like that there is no similar problem for last version of LSDK.
