check also directory starting with plat-

like, plat-omap, etc.

So, I should copy whole "mach-orion" folder to new kernel source tree, am I correct? An then what to do?

Sertac,

Starting point will be, arch/arm.
make platform base CPU SoC code and serial up.
If u able to make these things up, then its addition of pheripherals.

Harishkumar,
 
I already know my SoC name, it is Celestial CSM1203, and it is not available in any official kernel source tree ( the last one I checked it 3.4.1 10 minutes ago).
 
Since it is not available in the original kernel source, we had to make those thousands of changes one-by-one, and it would take years, right?
 
Am I correct?

Sertac,

Also, if u know ur chip SoC name, u can find whether open source linux kernel may have already support inbuilt in it. u can google around it, before deciding to port.

Sertac,

From your present source, u can find the Celestial SoC change.
check for arch/arm folder.

then in corresponding drivers, like usb,serial,video etc.

Dear Harishkumar;
 
Thank you very much for your quick answer.
 
Where can I find related Celestial SoC & driver patch file?
 
Best Regards

Sertac,

Basically u need to have Celestial SoC & drivers related patch.
Then, u can download desired kernel or latest 3.3.x.

Apply and do the forward porting. It won't be straight forward, u need to re-write a bit.
U can always refer any other celectial SoC family in latest kernel source or other ARM9 family.

see -> arch/arm/

Dear All;
 
I have a digital satellite receiver (named Chipbox), which uses linux kernel 2.6.12.5.
 
Main chipset name is Celestial CSM1203 ( It is ARM926EJ-S core).
 
The original kernel source (and all other sources) can be downloaded here: http://www.merihvideo.com.tr/chipbox-source.php
 
I would like to add some functionality (Such as CIFS, USB WIFI...) to my STB. In order to do that, I need to cross compile new kernel.
 
However, the chipset provider ( Celestial) does not provide a new kernel to do this. They just compiled 2.6.12.5 for about 5-6 years ago, and they didn't do a new kernel from that time.
 
So, I need your helps:
 
1) Celestial has done a lot of modifications on the original 2.6.12.5 source ( drivers, headers, definitions...) All these changes can be seen by using MELD tool.
 
2) In order to have a new kernel ( Such as 2.6.35.13) which can be running on my chipbox, what are the steps should be done one by one?
 
Can you please explain for a newbie please?
 
Best Regards
 
Sertac
