Connecting using ST-Link for STM32H745 Discovery Kit is not working.

Hi ,

Additional to this I will need some Technical Support on the Board Bring-up . Please forward me the Technical Support Person Email ID .

I have a Project using STM32H745XI Micro Controller , I have followed previous known steps to Generate Source code using STM32CubeMX for STM32H745XI.

I have sucessfully built the files using the STM32CubeIDE for STM32H745XI Discovery Kit , I am not able to Debug the souce code connecting with using ST-Link on the Discovery Kit . Is there any special settings that needs to be taken care other than the following .

 I have installed the ST-Link Driver from the following link

Open On-Chip Debugger 0.10.0+dev-g30d1303 (2020-06-18-09:13)

The interface firmware FAILED to reset/halt the target MCU

Hi @kalvacherla.chandrashekhar​ ,

From STM32CubeProgrammer interface, try to perform a Firmware upgrade. Is that possible?

Does it resolve your issue?

Seems more likely that the H7 is bricked with user software, and the ST-LINK here isn't switching to DFU/Update mode. Don't think this board provides jumpers to disconnect SWDIO/SWCLK from the target.

Direct engineering support for STM32 products is typically rendered through the local sales office responsible for your account, and the FAE's stationed there.

Hi ,

Yes the STM32H7 was Bricked , I am able to now recover the board 10K resistance De-Soldered from R143 and Soldered on to R144 .( There should have been an Jumper provided or ,,, the ST-LINK should have had GPIO method to recovered the board )

After Going through the user manual it is mentioned in an Caution: :sad_but_relieved_face:
