I don't understand a little what to do... zImage size is correct (0xc00fca18-0xbfdc6000=0x336a18=3369496) __request_region: 0xbfdc6000:0xc00fca17 outside parent resource 0xc0000000:0xc3ffffff ERROR: bootm/zImage: failed to request memory at 0xbfdc6000 to 0xc00fca18 (3369496). Reverting "ARM: bootm: make sure we place the kernel in free memory" fix this problem. --- _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
