[U-Boot] u-boot problem for M501 Board after u-boot-2009

Hi friends, we have bought an IPAC-5010 Board from Artila which is based on M501sk... We need to change the partition table for flash which requires MTDPARTS support inside u-boot and which is supported after version u-boot-2009.06... I have downloaded many u-boot versions and realized that there were no problems until version u-boot-2008.10 however I could not manage to boot the board with versions after u-boot-2009.01... After flashing the board and giving power to the board, all I see is two dots and everything stops afterwards... Has anyone already managed to run u-boot-2009.06 or higher versions (which includes MTDPARTS support) on board M501sk ???
