NUCLEO-H743ZI2 and NUCLEO-F722ZE does't debug in Mbed Studio

Hi, I am trying do start debug Nucleo boards in Mbed Studio 1.4.4.
NUCLEO-F722ZE uses Stlink v2.1 built in and NUCLEO-H743ZI2 Stlink v3.
I have started with mbed-os-example-blinky. It compiles without any errors but gives “Timeout waiting for gdb server to start.”
Any advice what to check?

I have updated pyOCD to version 0.33.0 and now after press Debug program i get:
Could not complete debug: Request reset failed with message: PyOCD failed to reset the target, please check the logs for more information

Run program is working (automaticly but it uses mass storage).

I did simple project in ST Cube , compile and debug it in CubeIDE and debug works like it should.

It looks like PyOCD does not support those ST microcontrollers? I have checked it using list --targets command. Results (deleted other types then ST):

stm32f051 STMicroelectronics STM32F051 builtin
stm32f103rc STMicroelectronics STM32F103RC builtin
stm32f412xe STMicroelectronics STM32F412xE builtin
stm32f412xg STMicroelectronics STM32F412xG builtin
stm32f429xg STMicroelectronics STM32F429xG builtin
stm32f429xi STMicroelectronics STM32F429xI builtin
stm32f439xg STMicroelectronics STM32F439xG builtin
stm32f439xi STMicroelectronics STM32F439xI builtin
stm32f767zi STMicroelectronics STM32F767xx builtin
stm32l031x6 STMicroelectronics STM32L031x6 builtin
stm32l432kc STMicroelectronics STM32L432xC builtin
stm32l475xc STMicroelectronics STM32L475xC builtin
stm32l475xe STMicroelectronics STM32L475xE builtin
stm32l475xg STMicroelectronics STM32L475xG builtin

As I can see many micros are missing. Does it mean we can not debug many of Mbed ready boards?


of course you can debug only targets what you have a tool for. Mbed Studio does not do it itself and needs a tool for that. In this case the pyocd but if pyocd does not support your target…
You can check issues of pyocd repo - Search · stm32H7 · GitHub
