I am not able to distinguish between the images as they are in binary form, I noticed that the smaller size image can boot in Qemu. I normally put the image into an SD card of the real hardware to boot. so it is quite difficult for me now to distinguish. >From the debug info from gdb you provided, the file clearly > is not a raw binary file -- the initial bytes seem to be > largely ASCII text.

Does Qemu provide such a tool or do you know any? br!
