STM32MP135 Bare Metal Project Debug Issues

[robbie-galfrin]

Hi, 
Purchased the STM32MP135F-DK.
Opened in STM32CubeIDE a Bare-Metal Project for this specific DK, with default IOC configurations, and only added a simple UART message in main to test.

Project Build went fine, But unable to debug.

The hardware setup:

Power USB-C cable connected.

ST Micro USB cable connected, and ST-LINK debugger is detected.

Boot Toggle Switches configured to Forced USB boot for programming (All 0s)

No SD card inserted.

ST-LINK debugger updated to latest version using the upgrade utility.

Things I tired:
1. 

In debug configuration, tried selecting Debug Probe ST-LINK GDB Server
Those are the debug configurations:

I get the following message:
"Failed to start GDB server. Error in initializing ST-LINK device. Reason: (4) No device found on target."

Tried in ST-LINK GDB Server mode to change the Reset Behaviour, modify the frequency, didnt help.

Tried Debug Probe ST-LINK(OpenOCD) with the following configuration:

I get the following text:

Also tried using STM32CubeProgrammer and attempted connecting to the DK, with various configurations, I only get "Error: Cannot identify the device"

I tried all the above on two different Dev Boards, identical results.

How can I run a bare- metal project on this development kit? 
Please help me with this.

Hi, I havent before but have now.

I have switched to engineering mode boot pin configuration on the board. 
Besides this I have performed all steps in the Getting Started page. 

I still get the following error:

I would very much appreciate any assistance.

Best Regards,

Hello @robbie-galfrin ,
You tell me in your first message that all boot pins are at 0. But it should not. It should be in engineering mode, with boot pin number 3 toggled. It is precised in the first chapter of the article I mentioned in my message. Can you test again the steps of the article with using this boot mode ? 

Kind regards,
Erwan.
