[U-Boot-Users] Unable to boot linux on ARM based board: gunzip hangs

Hi, I am trying to make Linux work on omap 850 based board which has an ARM926EJS. I have u-boot ported and installed on it and minimal linux support for the board is also there. The kernel image is in format expected by u-boot and I have followed all the needed steps like using mkimage etc. While uncompressing the linux image the system hangs, in gunzip function which is defined in inflate.c. No error is returned, it just hangs. I have checked whether the image overwrites itself after uncompression, but it does not since the addresses etc are given appropriately. I am thinking may be the DDR SDRAM might not be initialized properly (like refresh rate etc), but then how come u-boot is running properly?

Any pointers?
