...and are you (Alshine) loading your application in a valid location? I see 0x00002000 and following. I suspect those locations are used by your version of u-boot. You probably want to link your test app at 0x400000 or somewhere up high like that. >> => bootelf 400000 >> Loading .init @ 0x00002000 (972 bytes) [snip] >> ## Starting application at 0x00002044 ... gvb ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ U-Boot-Users mailing list U-Boot-Users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/u-boot-users
