Hi to all again,

I would very much like to know how to downgrade an OS Kernel, namely, Kernel 2.6.24 to 2.6.23 in
the Angstrom OS - how would I do this ? what tools do I need ?

Here is my GUESS:

a) open 'System Info' Applet get GCC version there
cool.gif install GCC version listed in the Applet (how do I do that ?)
c) Install kernel source code of 2.6.23
d) make zImage
e) load zImage to Card, replacing zImage that came with initrd.bin originally.
f) re flash C1000

Where am I wrong ?

I really need to know exact steps ... Is there a guide somewhere ?

many thanks, Allelectrix

Rather easy...

- Get the appropriate kernel modules from the Angstrom akita feeds (ipkg files) and install them
- download the corresponding kernel image
- rename the downloaded kernel image to zImage.bin
- put the kernel image and the updater.sh script to a FAT formatted CF or SD card
- make sure there is no initrd.bin on the root directory (because that would reflash the entire device)
- reflash the device (again, make sure in advance there is only the zImage.bin and updater.sh on the card, no initrd.bin)

Hope that helps.
