Developing an nrf51822 based embedded device with Qt Creator and Debian

I'm currently developing an nRF51822-based embedded device. Being one the Qt/Qt Creator maintainers in Debian I would of course try to use it for the development. Turns out it works pretty good... with some caveats.

There are already two quite interesting blog posts about using Qt Creator on MAC and on Windows, so I will not repeat the basics, as they are there. Both use qbs, but I managed to use CMake.

Instead I'll add some tips on the stuff that I needed to solve in order to make this happen on current Debian Sid.

• The required toolchain is already in Debian, just install binutils-arm-none-eabi, gcc-arm-none-eabi and gdb-arm-none-eabi.
• You will not find arm-none-eabi-gdb-py on the gdb-arm-none-eabi package. Fear not, the provided gdb binary is compiled against python so it will work.
• To enable proper debugging be sure to follow this flag setup. If you are using CMake like in this example be sure to modify CMake/toolchain_gcc.cmake as necessary.
• In Qt Creator you might find that, while try to run or debug your app, you are greated with a message box that says "Cannot debug: Local executable is not set." Just go to Projects →Run and change "Run configuration" until you get a valid path (ie, a path to the .elf or .out file) in the "Executable" field.

Cheers!
