Open reimplementation of the Quan Sheng UV K5 v2.1.27 firmware
This currently works for me, but use at your own risk.
Compiler
arm-none-eabi GCC version 10.3.1 is recommended, which is the current version on Ubuntu 22.04.03 LTS.
Other versions may generate a flash file that is too big.
You can get a correct version from: https://developer.arm.com/downloads/-/gnu-rm
Building
To build the firmware, you need to fetch the submodules and then run make:
git submodule update --init --recursive --depth=1
make
