Dear STMicroelectronics Support Team,
I am working on the STM32F407G-DISC1 (STM32F4 Discovery) board and I am unable to watch printf() statement in SWV ITM Console output in STM32CubeIDE.
To enable the SWO trace output, I referred to the user manual and identified that SB12 (SWO) was in OFF state by default. Following the recommendation, I removed the 0-ohm resistor between the SB12 pads on the backside of the board and directly shorted the pads using solder to connect the SWO signal to PB3.
I also attached an image of the soldered SB12 pads for your reference.
Here are the board details:
- **MCU Model**: STM32F407VGT6
- **Board**: STM32F4 Discovery
Could you please advise if any additional configuration or hardware action is needed for the SWO functionality to work properly?
Request you to send me a reference video link for any modifications mentioned by you.
Thank you for your support.
Best regards,
Vakati Hemanth ,
