Possible endian issue #144

Open CyberLeo opened 4 years ago

I have discovered an issue with endianness in the generated image file.

I've built version 0.3.12 on PPC64 (big-endian) and I noticed that the checksums and header information in the generated image file appears to be byte-swapped compared to that from an Intel system. The stored images are thus not portable from one arch to another. Within a given arch, however, the software functions perfectly.

Invalid header checksum [0x9FB6F40D != 0x0DF4B69F]

I can provide example images upon request.

sorry, currently only little-endian is supported. Actually, I have no idea abot add little-endian and it's not easy for us to add support in the feature.
