STM32L053R8 (NUCLEO) Debugging using Atollic TrueStudio v9 - SWD, SWO, SWV

[Mario Simunic]

Hi,

I have NUCLEO-L053R8 board. I'm started to use Atollic TrueStudio 9.0.

So, I would like to monitor the value of a variable, but it seems like it can't be done using on board ST-Link/v2 debugger. I've tried to figure out why... So far, I've got no reliable info.

Other thing that is very interesting in TrueStudio is Serial Wire Viewer (SWV). Also, it seems like MCU STM32L053R8 is lacking SWO so there is no ability to get working SWV.

What about JTAG connection on STM32L053R8?

If I use ie. Segger J-Link, shall SWV work then?

The CM0 parts lack SWV and JTAG, they just use the simpler two wire method.

Keil provides a similar debug output using a method whose name escapes me right now.

Could you find a USART TX pin you could use at a high baud rate?​

I could use one of two UARTs.
