Thanks Sascha! Before applying the recommended change the trace showed: uncompress.c: memory at 0xc000000000, size 0x00300000 uncompress.c: uncompressing barebox binary at 0x000000c000002b60 (size 0x00030def) to 0xc000100000 (uncompressed size: 0x0005a9a0) uncompress.c: jumping to uncompressed image at 0x000000c000100000 After applying this configuration, the .img file was increased (as expected) and the trace shows: uncompress.c: memory at 0xc000000000, size 0x00300000 uncompress.c: uncompressing barebox binary at 0x000000c000002480 (size 0x0005a9a4) to 0xc000100000 (uncompressed size: 0x0005a9a0) uncompress.c: jumping to uncompressed image at 0x000000c000100000 Indeed is seems link an uncompressed image because the sizes of the "compressed" match to the uncompress (well except 4 bytes which probably indicate the image size or the compression type (just a guess)). I assume that the decompress function detects the header and know that it is an uncompressed image and then just copy it to another location (in my case 0xc000100000). Can we avoid this step? Since the image was loaded into SRAM we wish to run locally without the extra relocation (which also takes simulation time).
