Blink Example setup/loop not working as part of larger project (for Teensy 3.1)

[chlirre]

Background

I am currently attempting to port the firmware for synth module Ornament & Crime to PlatformIO to be able to develop under later OS X versions.

In addition to being written for Teensy 3.1, the O & C project has some restrictions in terms of compiler.

gcc 4.8

Which is enforced by stating the toolchain-gccarmnoneeabi version.

I am specifically porting the alternative firmware Hemisphere.

I'm on OS X 10.13.2, running PlatformIO IDE (with PlatformIO Core, version 5.0.4).

I tried the suggestions found at https://github.com/platformio/platformio-core/issues/566, without success. I tried prepending As & Zs to the main file without luck.

I cannot tell if the issue lies within PlatformIO, this platform or elsewhere. All I know is https://github.com/Chysn/O_C-HemisphereSuite builds, uploads and runs fine with the Arduino IDE and that I've made as little changes as possible to that code.

The issue

The project is in a state where everything builds just fine (apart from some warnings). Uploading/programming (with both teensy-cli and teensy-gui) seems to work just fine.

But beyond that point, there is no indication of the firmware running. As in:

• no serial output.
• Nothing showing on the screen.
• the case of borrowing the "main/loop" file from the led blink example, the LED is not blinking.

Not working (not blinking)

Loop/setup

Hi @chlirre ! There might be plenty of reasons. First, you need to make sure that the package versions are identical (toolchain, framework, libs, etc). I also noticed you use -O2 optimization. Have you tried other levels?

BTW, this line [email protected] seems invalid to me, probably should be something like toolchain-gccarmnoneeabi@~1.40804.0

[chlirre]

@valeros I tried a few different optimizations, but the instructions for compiling the original project explicitly state 4) select Faster (= o2) in Tools > Optimize (teensyduino 1.34 and 1.35) (https://ornament-and-cri.me/firmware/) so I stuck with that.

Could you please try to compile your project in verbose mode and attach the log here?
