Some notes on the FiiO M3K Mini HiFi. As of July 2021, the M3k is available from amazon.com . A build of rockbox for the device exists, and works just great!
This is the native port, recommended nowadays.
This was the first “port”, rockbox more running in userspace as alternative to the native firmware. On each start, one has to select “rockbox”. The native port is recommended nowadays.
# Fedora34 sudo dnf install gmp-devel git git clone git://git.rockbox.org/rockbox cd rockbox/tools # This should now build the crosscompiler for us vi rockboxdev.sh ### I customized the path, to not build into /usr/local ./rockboxdev.sh # At this point I needed to customize the PATH to point at the compiler: export PATH="/home/chris/Downloads/rockbox/rockboxbin/bin:$PATH" # Do a build mkdir build cd build ../tools/configure make -j make zip # This should leave a zipfile which we can deploy as .rockbox # to the sdcard and start the M3K! cd .. # Do a build of the simulator mkdir buildsim cd buildsim ../tools/configure make -j make fullinstall ./rockboxui
