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
========================================================================= $ bdinfo arch_number = 0x0000056C env_t = 0x00000000 boot_params = 0x80000100 DRAM bank = 0x00000000 -> start = 0x80000000 -> size = 0x04000000 ethaddr = 00:50:43:09:01:1C ip_addr = 10.100.144.42 baudrate = 115200 bps

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.
