Yocto questions: Custom Cyclone V Board with HPS
« on: March 03, 2022, 02:58:40 pm »
Hi all,

I've been looking into Yocto for the last few weeks, that's the extent of my knowledge. I've been reading about bitbake and recipes and device tree sources. I managed to set up a CROPS system (WSL2) where I was able to compile through the core-minimal project. I also cloned the meta-intel-fpga repository with recipes for some of their boards.

The thing is this, I have a custom made board on which for the time being I'd like to just interface the UART and the SD interfaces. I know the board works correctly, as the developer provided us with a buildroot image. Unfortunately our previous project was based on Yocto and the colleague managing that left.

I'm stuck as to where to go from here. I can generate a new .dts file, using some of the other boards as a base, editing out what I don't need. I just don't know how to tell bitbake that this is a new DTS to create a new DTB.

Other question, once the image is generated, how does the system know which hardware is the correct one, if when the Cyclone-V image is generated the config file has a bunch of DTS's which are all different?

Any pointers in the right direction are welcome. Happy to clarify things if I'm a bit vague.
