Thank you Cedric. I need to access the uio_pruss module in kernel v3.14. How do I apply this patch file in Robert C Nelson’s build environment?

Cedric – I get a « Patch format detection failed. » error when I try to apply your patch file. Any ideas?

Chris: to apply the patch, go into the KERNEL directory and type patch -p1 < patch-to-enable-pruss-into-kernel-ti-3.14.patch If you still have trouble, I'll try to patch a fresh kernel pull from github, Robert might have made some changes 🙂

Hi Cédric,
it’s been a long time since you came up with these fixes. Have it been included in some kernel image available somewhere? Or should I apply the patches and compile the kernel?
Thanks, Luca

Yes Robert has them included in V4.X branch of the kernel
