@Jing_Guo @spikerguy @stuartiannaylor To build Radxa mraa on Manjaro, you need to apply the following patch before building: curl https://github.com/eclipse/mraa/commit/aaa0a5cd4e401bde4fb3691dd4e6c70a5c61e031.patch | git apply
That repo is maintained by @Stephen and @ken so I’m not touching it for now. I’ll make sure Zero 2’s mraa is merged upstream though (just realized I need to write this piece as well 
).
