Forum Post: How to create uImage from zImage

Hi ,

Please let me know how to create uImage from zImage for AM3517evm.

I tried to convert the zImage to uImage using the following command

mkimage -A arm -O linux -T kernel -C gzip -a 80200000 -e 80200000 -n myuImage -d zImage uImage

But uboot is not loading this uImage file, Below is the errors from uboot promt 

Error:

Uncompressing Kernel Image ... Error: Bad gzipped data
GUNZIP: uncompress, out-of-mem or overwrite error - must RESET board to recover

Thanks,

P.Ashok
