Clone source code

git clone https://github.com/meisreallyba/padavan-4.4.git

Prepare toolchain

cd padavan-4.4/toolchain-mipsel

# (Recommend) Download prebuilt toolchain for x86_64 or aarch64 host
./dl_toolchain.sh

# or build toolchain with crosstool-ng
# ./build_toolchain

Modify template file and start compiling

cd padavan-4.4/trunk

# (Optional) Modify template file
# nano configs/templates/K2P.config

# Start compiling
fakeroot ./build_firmware_modify K2P

# To build firmware for other devices, clean the tree after previous build
./clear_tree
