ARM Linux Kernel Update

ARM Linux Kernel Update

[Satay Epic]

Hello,

I've an ARM SL3516  board with Linux 2.6.15 and I've tool-chain setup.
I could able to compile the GPL source.  This board has red-boot.

I would like to update the kernel to 3.8.24.  My first attempt so not
sure about anything I should know, gotchas  etc.

Any advice about the compilation , config will be appreciated.

Redboot has option  to upgrade kernel.  So I guess I can use it once I
get the kernel image compiled.

I tried using the  existing  ".config" but not sure some SL3512
specific options would work?

Looking at the distribution,  I don't see the  "mach-sl2312" listed.
Can you just copy it from the old distribution and does it work this
way?

There is this "mach-gemini" but it seems only for some W boards.

Thanks in advance

3.8.24 is also really old already, try going to 4.1 or 4.3 right away,
and submit any patches that you might need for integration into
mainline Linux once you are done.

See http://git.openwrt.org/?p=openwrt.git;a=tree;f=target/linux/gemini;h=b74c3d8f0100e2ac8a4d71c4d23c082db2993e63;hb=HEAD

for a tree that has some of the missing parts for gemini, including a
config and some drivers that might be helpful. This is based on 4.1
and should be easy enough to forward-port to 4.3 if you want.

Start with the config-4.1 file from openwrt.

mach-gemini is what you want.

I have recently started to migrate the Gemini family to device tree.
If you're still working on this board you might be interested.
See:
https://dflund.se/~triad/krad/gemini/

If you have vendor kernel source under GPL for the SL3516 I'd
be interested to see it, please mail me privately if you have so I can
get a copy somehow.

Yours,
