Which FreeRTOS library do you use? PlatformIO Registry
You can run in Terminal pio run -v, it will show dependency graph.
The errors above mean that you didn’t build C/C++ files where these symbols are declared.
Thanks for your reply.
When I generated code, I used FREERTOS MiddleWares at “STM32CubeMX”.
I don’t know what to do… please help me.
$ pio run -v
