"Multiple definitions of hlptim1" when running FreeRTOS project #5

Closed ES0R closed 2 years ago

ES0R commented 2 years ago

I completed the LoraWAN end node tutorial for the LoRA E5 Dev board (https://wiki.seeedstudio.com/LoRa_E5_Dev_Board/#freertos-lorawan) and continued to the RTOS part. However, when running the code unaltered, it fails to compile. This is the case for both FreeRTOS and FreeRTOS_AT. I have been unable to locate the error. I have attached the console log for when it fails.

I just ran into this same issue when building the different FreeRTOS examples. There is a simple fix.

For each project, in Core/Inc/main.h, find the line:

LPTIM_HandleTypeDef hlptim1;

and change it to:

extern LPTIM_HandleTypeDef hlptim1;

and all three projects will build without any errors or warnings!
