zImage built for dev boards

Altera_Forum · ‎05-07-2006

I prepared some zImage for dev boards with buildroot tools.

They use minimal config ~/download/kernel.config .

To use, open the quartus II project, and download sof to your board.

for altera nios II dev boads, altera/kits/nios2/examples/verilog/

eg. niosII_stratix_1s10/standard/standard.sof

for DE2, DE2_System/DE2_demonstrations/DE2_NET/DE2_NET.sof

Then, open a sdk shell window, with Start-->Programs-->Altera-->Nios II 5.1-->Nios II SDK Shell

nios2-download -g zImage

nios2-terminal

or find them on Jhdar's site, (thanks a lot to his help)

for 2s60es and 1s10es, use 2s60 and 1s10es 's zImage.

Hope these will help.

PS. Please let me know if the updated link work or not?

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.
