Remote Debugging (enigma2 c code) - SimonCapewell/enigma2 GitHub Wiki

On your Enigma2 box

• Install gdbserver opkg install gdbserver
• Install python symbols opkg install python-dbg
• Launch gdbserver
  • To attach to Enigma2 if already running gdbserver localhost:9999 --attach $(pidof -s enigma2$)
  • To launch a new Enigma2 instance gdbserver localhost:9999 /usr/bin/enigma2

On a Windows dev machine

• Install MSYS2
• Follow installation steps, in particular step III updating packages
• Install gdb-multiarch with Python support pacman -S mingw-w64-x86_64-gdb-multiarch
• In Visual Studio Code, create a launch.json

• Press F5 to run
• After a wait while debug symbols are pulled across from the box, you'll be able to set breakpoints, press pause, etc.

Some gotchas

• It can sometimes take a minute or two for debug symbols to be pulled down from the box before you see any signs of progess.
• sourceFileMap isn't completely correct yet, so some files are not located correctly when debugging.
