Dear list, this is more of a request for help, as I am not sure if my current analysis is correct. The problem I am having is that the kernel current master does not boot and fails with: Error: unrecognized/unsupported machine ID (r1 = 0x00001030). My setup is: phyBOARD-WEGA-AM335x kernel: master with multiv7/omap2plus defconfig barebox: master with phycore-am335x image Git bisecting lead to the DEBUG_RODATA change, which is now turned on for arm and arm64. Google brought up this thread: http://www.spinics.net/lists/arm-kernel/msg511355.html Which brought me to the bootm.c in barebox to check if there is enough space for decompression. I found the assumption of a compression factor of 4 also in the barebox. What puzzles me is that this assumption still holds true even for DEBUG_RODATA, at least for my case, though. With DEBUG_RODATA turned on, the compression ratio went up from 2.9 to 3.5. So my guess is that the kernel is relocating and barebox does not account for this case. Additionally I found some recommendations in git/kernel/Documentation/arm/Booting which I think should be taken into consideration for barebox. With the attached patch, everything works fine (tested on one single board 256MiB RAM only). So, if anyone has more information, I am happy to learn.
