STM32WB55RGV6: No output after west flash #40825

Closed KevTango closed 2 years ago

KevTango commented 2 years ago

Describe the bug After executing west flash to a custom board with an STM32WB55RGV6 microcontroller, I can not observe any output. I have successfully flashed the P-NUCLEO-WB55 which contains the same SoC as the custom board and can observe an output.

To Reproduce Steps to reproduce the behaviour:

  1. Connect SWDIO, SWCLK, T_VDD, GND from the P-NUCLEO-WB55 board to the custom board
  2. west build -b nucleo_wb55rg -s zephyr/samples/hello_world --pristine
  3. west flash --runner openocd
  4. Open PuTTy to view the output

Expected behaviour Hello World! being outputted on terminal

Impact Showstopper

@KevTango Thanks for reaching us, but there is not much we can do, as you mention this is working on upstream board and we have no information or way to test your custom board. Hence, I'm closing the point.
