nerves_system_rpi3 VS linux-xlnx

Once I understood this, I was able to finish step 2 above by learning how to use Buildroot and creating the kernel and dtb. Steps 3, 4, and 5, I use nerves_system_rpi3 as base and made modifications. This is a difficult part to describe what I did.

For the DMA I found several examples by xilinx and independent folks demonstrating several way in which it can be done in linux. I started with the xilinx_dma.c driver that is provided by xilinx along with a test driver that is found here. Long story short, it didn't work. The test failed and nothing came of it.

The Framebuffer Read IP has kernel driver and you can find the device tree bindings for it here.

Has anyone used custom configurations on the Xilinx KV260 AP1302 Image co-processor? I plan to look at the different camera options for Kria KV260. The documentation is not publicly available. This was the only code I could find: https://github.com/Xilinx/linux-xlnx/blob/master/drivers/media/i2c/ap1302.c

Thank you for your response. The remote repo I was pointing to was Xilinx/linux-xlnx, but I was pointing to a branch with an older commit, which was the default version for PetaLinux 2018.3: Xilinx/linux-xlnx/tree/xlnx_rebase_v4.14

https://github.com/Xilinx/linux-xlnx the petalinux repo has some history, I don't know how long it goes back though (I am with the phone)
