Nucleo Board + IAR -> Can I get Data logging?

Hi everyone,

I have a STM32F072B Nucleo board (god knows why, should have listen to good advises -.-) and IAR Workbench with the 32Kb code limit version. V7.40.

In an attempt to get more familiar with IAR tools I was looking for ways to monitor data in a graphic and monitor code execution cycles.

So I tried to use the tools under ''ST-Link''.

First what it seemed easier. Data logging. I configured the SWO to know the target is at 48Mhz and the SWO clock to 2000Khz. Opened the data log window, added the variable I wanted and waited... for nothing. There is no data getting into the graph.

I am not sure if I did anything wrong, all my drivers are installed, I tried also using the SWO trace (after some messing arround with the config) and nothing happens.

Could this be because of the dam Nucleo board or am I doing something wrong?

Help is really appreciated as I tried for quite a while to search for info on this but it seems everything I am doing is correct (obviously there is something wrong with either my steps or the board)

Hello Afonso,

The Data logging that you want enable is the Power Log Setup window?

If not, could you sent a print screen of this window?

Hi Wittle,

Unfortunately it always gives me an error when I try to post with an image.

The window I am talking about is opened by going''ST-Link->Timeline''. Is this what you wanted to know?

Don't Cortex-M0 parts have very limited SWO functionality?
