Hi Uday, from the second log you send me (with Rudy's UBL) it looks like everything is fine except that the (hardwired) third level Boot Loader (U-boot) is not found. As I sayed before my program is only an (internal) test tool and far away from a real program. Check the source for filenames / pathes used.
