Regarding error applying patch to kernel 3.12.9


I was trying to get the linux kernel ready for the BBB.

Download the 3.12.9 kernel and apply the patch existing in the sysplay repo(bbb-master/Images/ELPImages/epid_dts.patch). I tried this patch but getting errors(could not apply the patch and asking what files to be patched), i am not getting exactly which patch do i need to apply and for what files into the 3.12.9 kernel this patch is required.

Best Regards,
Vinay Chikkadi

It took a little bit to find this repo:

You might want to contact the author..

Why 3.12.x? are you following some book/text?


Hi Robert,

sorry for not mentioning the URL.

Basically was trying to prepare the 3.12.9 kernel for BBB.
i am actually following some author here.

As i had few driver codes for 3.12.9 kernel, which i wanted to experiment for understanding driver frameworks.


Seems to apply cleanly:
