padavan

This project is based on original rt-n56u with latest mtk 4.4.198 kernel, which is fetch from D-LINK GPL code.

Enhancements in this repo

• commits has beed rewritten on top of hanwckf/rt-n56u repo for better history tracking
• Optimized Makefiles and build scripts, added a toplevel Makefile
• Added ccache support, may save up to 50%+ build time
• Upgraded the toolchain and libc:
  • gcc 10.3.0
  • uClibc-ng 1.0.47
• Enabled kernel cgroups support
• Fixed K2P led label names
• Replaced udpxy with msd_lite
• Replaced Web Console with ttyd
• Upgraded libs and user packages
• And a lot of package related fixes
• ...

Compilation steps

• Install dependencies

  # Debian/Ubuntu
  sudo apt install unzip libtool-bin ccache curl cmake gperf gawk flex bison nano xxd \
      fakeroot kmod cpio git python3-docutils gettext automake autopoint \
      texinfo build-essential help2man pkg-config zlib1g-dev libgmp3-dev \
      libmpc-dev libmpfr-dev libncurses5-dev libltdl-dev wget libc-dev-bin

  Optional: install golang (and add it to PATH), if you are going to build go programs
• Clone source code

  git clone https://github.com/vb1980/padavan-4.4.git

• Modify template file and start compiling

  # (Optional) Modify template file
  # vi trunk/configs/templates/K2P.config
  
  # Start compiling with: make PRODUCT_NAME
  make K2P
  
  # To build firmware for other devices, clean the tree after previous build
  make clean

Package Development

• Makefile examples
  • Makefile project
  • CMake project
• Compiling a single package (cd to trunk first)
  • build: make libs/libpcre_only
  • clean: make libs/libpcre_clean
