Putty on linux not showing received data from stm32F407VG

Question

I am new in microcontroller and I was trying to send data from stm32F407VG to usb serial port connected to st-link using usart2 and HAL. I tried to print the data received on PuTTy . On PuTTyI set my port which is /dev/ttyACM0 and selected the baud rate as 9600 which is matching with the baud rate of my stm32F4 board.

But PuTTy is not showing anything, Note that I am using Linux Mint.

Can anyone help me out ?

Use an oscilloscope to verify that your SBC is actually sending data. — sawdust, Oct 27 '21 at 01:33

You cannot send data using HAL_UART via ST-Link. ST-Link provides only Serial Wire Debugging/Trace. You should select different UART/USART port to connect your PC's com port.
