Cant print on SWV ITM Data Console

[asim khan]

I am trying to Debug with SWO and SWV in STM32CubeIDE. But i am not getting any thing on SWV ITM Data console and Timline Graph. As you can see in live expression window count is incrementing as expected. My clock is running on 24Mhz.

Is your CoreClock indeed 24 MHz? This is not the oscillator frequency,

The value must be equal to global var SystemCoreClock after return from SystemClock_Config() in main(), in MHz.

For example if SystemCoreClock is 64000000 specify 64.0

Also you must click on the ITM console start button, not earlier than when the debugger stops on the first breakpoint (usually at main). Otherwise it won't start.

Clock are same and I first clicked the console start button before hitting resume for debugging.

Which STM32?

STM32F303-->STM32Discovery board

The following helped me. On my STM32F3DISCOVERY board, the SB10 jumper was not soldered. Soldered SB10 and SWV data appeared. This is because the SWV data is transmitted on the SWO PB3 pin on the STM32F303VCTx.

On my STM32F429I Discovery-DISC1 I had to solder SB9 then it worked.

Two things to check... 1. Your SWO clock freq... must be the same as main clock, in my case 180 Mhz. 2. Solder the bridge for you board, in my case SB9..... for SWO

How did you manage to get it work?
