Stm32cube framework, Not getting uart output on VCP on a Mac

I am having the same problem as this:

I’m using a nucleo-l432kc. I posted the .ioc and main.c to the ST community forum. A member compiled and ran the code on a PC using STM32CubeIDE. The PC com port received the “Hello World” message. My Mac compiling in Platformio and running screen as a terminal emulator gets nothing.

Has this been resolved? Is there a “monitor” setting in the platformio.ini I need to set? Something else?

BTW, I made a simple sketch and used the arduino framework. Serial.println(“Hello World”) works fine.

Changing the toolchain/IDE environment in STMCubeMX from EWARM ( the default ) to STMCubeIDE fixed the problem.
