I am downloading the image to SDRAM and then writing this image to dataflash using uboot copy (cp) command like this, u-boot# cp 21000000 14a000 192000 Once I boot the system, jffs2 is mounted as rootfs but then I continuously get the "Node header CRC failed" messages and then finally kernel panic with no init found. I'm using mkfs.jffs2 to create an image like, mkfs.jffs2 -p -l -e 0x2100 -s 0x210 -n -d /home/me/rootdir -o jffs2.img I am totally lost and cannot figure out the reason for the errors. I'd appericiate if anybody help to find out the reason.
