PB3-SWO for STM32C071RBT6

AndrewFFFF · ‎2025-03-31

Hello to everyone.

I'm using the board NUCLEO-C071RB, and now i want project my board.

I have a question about the pin PB3:

From the schematic it seems PB3 = SWO but if i try to configure the pin with STM32CubeIde i don't find that option.

The STM32C071RB doesn't have SWO.

Presumably, the schematic is a general one for any Nucleo-64 board - covering the case where the Target STM32 does have SWO.

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
