Hi Jeremy, I understand most of what you've got here, thanks, but I'm confused on the SRC_URI="<your kernel git path>…". Where should I look for the kernel git directory? I'm running Yocto with a mirror directory and that contains git directories for all of the major pieces, but I don't see one for the kernel. The kernel source is in tmp/work-shared/raspberrypi3/lernel-source, but that is not a git directory.
Any pointers would be appreciated. Greg Wilson-Lindberg Principal Firmware Engineer | Sakura Finetek USA, Inc. 1750 W 214th Street | Torrance, CA 90501 | U.S.A.

So your tree should look something like: <your layer>/recipes-kernel/linux/ linux-raspberrypi_4.4.bbappend files/ <your patch> Instead of "files", it might be named "linux-raspberrypi". Hope this helps, Jeremy On Fri, Apr 13, 2018 at 2:41 PM Greg Wilson-Lindberg <[email protected]<mailto:[email protected]>> wrote: I'm working on a raspberry pi3 Yocto build from Qt's boot2qt project, it's running Yocto version 2.2.3, and Linux kernel 4.4.50. I need to back port some changes to a file in drivers/net/can/spi. I confused about where and how I set up the patch file. I have a linux-raspberrypi_4.4.bbappend file. Do I put the patch file in that, and If so, how do I indicate the path to the file?
