Hey Jason,
thanks for your reply!
Indeed, my first attempts were building the example with latest available gcc-arm-none-eabi-7-2017-q4-major. But I already read in this topic that version 6 is recommended. So I also tried to downgrade the toolchain, hoping that this step would solve my problems. I’ve tried all three version 6 toolchains but unfortunately the problem persists.
I’ve uploaded the project and the image binaries to GitHub. Maybe this will help someone to help me
Thanks again and best regards
Rafael
