Blanco stm32h757 programming first time.

[MVops]

Hey,
I have an STM32H757 that I’m trying to program for the first time.

When I try to program it using STM32CubeIDE or CubeProgrammer, I lose the ST-Link connection after programming one of the cores.
Changing the programming order doesn’t solve the issue.

The code has been tested on an evaluation board, where it runs correctly and behaves as expected.

Is there a recommended procedure or step-by-step guide for programming a blank MCU for the first time?

Best regards,
Matthias

Hello @MVops 

I think that this video together with the AN5286 and the AN5361 should help you.

Best Regards.

Ensure your power settings in the code are consistent with the board hardware. LDO vs SMPS.

Hey,

Thanks for the information.

I have already followed the documents and the video, but unfortunately without success.

However, there are some differences between the video and the documentation, as well as discrepancies between the documentation and what can actually be seen in the software.

The development board can be programmed without any issues.
I also used it to test the overall concept and flow of the code itself.

However, when I try to program a blank STM32H757 using the same settings, things go wrong.
The MCU does not get programmed, and afterward, it’s no longer accessible via ST-Link.
Following either the video or the documentation leads to the same result.

Attached are some screenshots showing my current configuration.

Best regards,
Matthias
