Hi,
Did you use "nand write.i" to write the kernel and "nand read.i" to read the kernel? the ".i" tells u-boot to skip bad blocks...
No I use "nand read $load_addr AppKernel" cause I didn't know we can use "nand read.i" - "help nand" doesn't display this information. I tried "nand read.i" and now it works fine but I still can't boot the kernel cause its crc is wrong I will flash the kernel again with "nand write.i" and check if it works.
Assuming you load the kernel to ram with tftp (and that "AppKernel" is an mtdparts partition in NAND), then you could do:
nand erase.part AppKernel tftp $load_addr uImage crc32 $load_addr $filesize nand write.i $load_addr AppKernel $filesize nand read.i $load_addr AppKernel $filesize crc32 $load_addr $filesize
To verify the CRCs match between what you load off tftp and what you read back from NAND.
