[Solved] Hello World program fails with "Illegal Instruction" in built-in file on RPi Zero W


I am getting this compiler error in one of the built-in files (variant.cpp) when building a trivial Hello World program. I am only getting it for the SAM/Due platform and not for the AVR/Uno platform.

Does anyone know if there is some simple work-around I could use here, or do I need to wait for an upstream bugfix?

This issue looks very similar to this one: Illegal Instruction [.pio/build/teensy40/src/main.cpp.o] Error 132 - #17 by maxgerhardt

Here is the console output (I am using the CLI):

Yep it should be the same issue as when compiling for a Teensy: The toolchain-gccarmnoneeabi package is not actually executable on the Rasperry Pi Zero W, due to some binary incompatibility.

Please do the following (actually pretty much the same as in the topic you’ve linked)

  1. download the toolchain-gccarmnoneeabi-linux_armv6l-1.90301.201121.tar.gz file the bintray on the Pi to some path, e.g. using wget https://bintray.com/maxgerhardt/pio-tools/download_file?file_path=toolchain-gccarmnoneeabi-linux_armv6l-1.90301.201121.tar.gz
  2. Use that downloaded file in the platformio.ini by adding
platform_packages =

Where the /home/pi/toolchain-gccarmnoneeabi-linux_armv6l-1.90301.201121.tar.gz must be adapted to match the actual downloaded path.

Then retry compilation.

Wonderful. That saved my day :smiley:
