Thank you for all the suggestions. I don’t know why I just received notification about the activity on this thread.
In any case, I will try the suggestions as soon as I can and report back. I suspect the maple version would work, since I think that’s the version of stm32 Ardiomp that I’m using in the Arduino IDI. I didn’t know it was available in PlatformIO.
I would prefer to use the default version in PlatformIO, which I believe is the newer version, so I’ll try the patch to see if that fixes it.
