A lot of boards load the image at 0x00400000. I would move this down and see if it helps. Your DTB is loaded way away from your image. I would load it 32K below (lower address) your uImage. It probably is only around 8K, 32K will give you plenty of room to grow (famous last words ;-). Try 0x003F8000. Combining the lower addresses should give bigger available chunks of RAM on startup. > When I use release.im, no problems. But when I use debug.im: > > Verifying Checksum ...
