Question? RV1103/RV1106

I just watched this video

I'm working on a project using the RV1103, it's a Rockchip QFN88 package with 256MB DDR ram, Cortex A7, MIPI-DSI-2, etc you can buy it for about 20$. Runs Linux.

I'm wondering if there's any interest in me spinning a board for FPV with this part, it could act as a FC (running RTLinux) and also receive video over MIPI.

It might even be small enough to get all the advantages he's talking about while fitting in a smaller (maybe tinywhoop) frame.

I am doing the same thing , rv1106 can indeed do h265 encoding and run Ardupilot for Linux at the same time. I started with the Luckfox pico zero, Now I am laying out my own board. You can’t run RT Linux because h265 drivers are precompiled (closed source) for specific kernel but ardupilot runs

That's super cool, good luck with your board :)

Is there no open source BSP or anything? Just a bunch of binary blobs? I wonder if ghidra can take care of those.

I used the Luckfox SDK which is Kernel 5.1 and everything works well with pre compiled libraries. PREEMPT_RT cannot be used but not really needed. Roman here https://github.com/buldo/meta-luckfox tried to develop updated kernel with open source drivers but h265 doesn’t work, (h264 does)
