How to redirect Printf to SWV Console in TrueStudio?

[karthik.arunachalam]

I have followed step-by-step set up as explained in http://blog.atollic.com/cortex-m-debugging-real-time-variable-watch-using-swv/swo but it didnt work for me. I get sometimes some random characters printed on the SWV console.

My setup:

IDE: TrueStudio

Hardware: NUCLEO-F410RB

Programmer: On-board ST-Link

Let me know if you need further details.

Please ignore my previous comment, the wasnt cleaned up so it was working with HSI not with HSE.

Is there such an article for STM32CubeIDE?

Now that I've migrated to STM32CubeIDE from Atollic TS, I can't get the SWV console to show printf messages.

The SWV ITM Data Console is working!

In Debug Mode - choose Window -> Show View -> SWV -> SWV ITM Data Console

When the SWV is opened, choose configure (wrench/screwdriver icon) and make sure that Hz rate is correct (can be set in Debug dialog when connecting with ST-Link or Segger-Link) - and check Port 0 (towards bottom of screen on far right - see attached.

of course syscalls must be included in the Src files of the project

So glad to finally get this working! Lots of small configurations to overlook.

To clarify for future readers, I believe "Core Clock" needs to match SYSCLK in the clock config tree.
