huh, Debian sid build doesn't work. Build with docker and Ubuntu 22.04 works.

docker run --privileged -itd --name duodocker -v $(pwd):/home/work milkvtech/milkv-duo:latest /bin/bash

docker exec -it duodocker /bin/bash -c "cd /home/work && cat /etc/issue && ./build.sh milkv-duos-musl-riscv64-sd"

But changing settings in home assistant bricked device. Fix it by shorting button pins on board.
