hi hippo,

i noticed that the zimage files are compressed in a gz format, is that possible to do so with a bz2 format since the last seems more size efficient.

Those are elf, and to be used directly to nios2-download.

The uncompress loader uses gz format internally, because there is a build-in gunzip inside the kernel library. It is possible to use bz2, but that would require adding the bunzip2 to the loader.

I noticed in the compressed directory the files vmlinux.bin and vmlinux.gz, so I concluded that you compress the bin with gz before transforming to a zImage, so my question wasis that possible to do so but with bz2 format, and how.
