If u able to make these things up, then its addition of pheripherals.

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?

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/ On Thu, Jun 7, 2012 at 2:36 PM, Sertac TULLUK <sertac@merihvideo.com.tr> wrote: 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?
