[U-Boot] GUNZIP: uncompress, out-of-mem or overwrite error

[Unnamalai Kanchi Bashyam]

Hello,

I have problem uncompressing the Kernel image by u-boot. It throws the message "GUNZIP: uncompress, out-of-mem or overwrite error - must RESET board to recover
resetting ...".

I have compressed and created u-boot image of the linux kernel by the below commands:

arm-marvell-linux-gnueabi-objcopy -O binary vmlinux vmlinux.bin

gzip --best --force vmlinux.bin

u-boot/tools/mkimage -n 'Compressed kernel for Littleton' -A arm -O linux -T kernel -C gzip -a 0x80200000 -e 0x80208000 -d vmlinux.bin.gz vmlinux.ub

The file sizes were
vmlinux - 5.7M
vmlinux.bin - 3.1G
vmlinux.bin.gz - 5.1M
vmlinux.ub - 5.1M

After loading u-boot, from u-boot prompt I issued following commands to boot kernel

I have enabled verbose debug messages in u-boot/lib/zlib.c

Why BUF_ERROR is (ie. inflate() returned -5) thrown by the zlib? Please let me know what could be wrong.

I am working on Littleton board with PXA310 processor and 64MB DDR SDRAM.
