All,

I would like to flash the kernel only. Is there a way to do this?

Will it destroy any of the in place configuration?

How are kernel size differences handled?

Thanks,
Dan

Dan,

If you place only the zImage file on the CF card, nothing else will be affected when you flash. The filesystem is contained in the initrd.bin. Flashing zImage only will not affect any of your installed files. I flashed r21 on my 5500, had problems with it and flashed back to the original 3.5.3 kernel without loss.

Obviously if you have anything other than a 5500/5000D (collie), you'll want to check the naming of zImage(.bin) and also place the updater.sh file on the CF card.

As long as you don't have an initrd.bin on the CF card, it won't flash the filesystem,

P.S. Do check that the kernel versions are the same (`uname -r`) otherwise, although the kernel will flash, it won't have any modules available (unless you install them before flashing).

P.P.S. Afaiu the kernel is contained in a seperate part of the flash.

For me on a poodle after flashing the kernel only, the device does not boot anymore.
I have to flash the filesystem too for making it working again.

Thast's odd - did the version change? `uname -r`

Did you rename the kernel zimage.bin and include the updater.sh when you flashed, as lardman explained in the previous post?
