Hi Kim

Did the image you created installed OK?
I used your Crcimage.sh and obtained the same result as before. I was 
already using pilgrim to create the crc files. One think that I forgot 
to report is when I use the crcimage(pilgrim) command it's returning a 
message

%crcimage nand.img
Input file size is not a multiple of 0x20000 - residue 0x1e000


Is that normal?
Thanks
