[Maratyszcza]

You should build for at least -march=armv6k

[Shivankit99]

Didnt quite understand you, could you please elaborate it a bit ?

[Maratyszcza]

You should specify at least -march=armv6k target architecture in compiler flags. E.g. by passing -DCMAKE_C_FLAGS=-march=armv6k when configuring the project.
