[U-Boot] Problems with ext2ls & SD

[DVM]

Hi

I am working on a port of 1.3.4 to the LPC313x and I am having some trouble
with the ext2fs. U-Boot reads blocks 0x00, 0x02, 0x08, 0x200. I modified the
code to dump the block data as it is read & verified that the data is
correct. 

The ext2ls command returns nothing, I guess thats because block 0x200 is
full of zeros bt that Linux box is quite happy to read the SD card. Can
anyone help?
