STM32H733VGT6 doesnt boot into program

[dpoettler]

Describe the bug
After uploading my blinking LED programm to my chip it doesnt blink. Uploading works without issues with the STLink V3 Minie, but the Chip doesnt seem to boot into the programm afterwards

To Reproduce
Write a simple blinking LED programm. (In my case on PIN PE8). Set pinmode and let the pin "blink" every half second in the loop. Upload the code and wait for nothing to happen.

The reason i think its not booting into the program at all was because i made a for loop that activates every pin because i thought the pin definitions might be wrong.

Expected behavior
Chip gets power and the LED on Pin PE8 starts flashing.

Desktop:

• OS: Windows 11
• Arduino IDE version: 2.3.7
• STM32 core version: 2.12.0
• Upload method: SWD via STLink V3 Minie

Board (please complete the following information):

• Name: STM32H733VGTx Generic
• Extra hardware used if any: STLink V3 MINIE

Additional context
Since I added the Generic Boards for this chip I am pretty stumped that it doesnt work. It doesnt seems like a hardware problem. I tested it with BOOTSEL on all possible Logic levels

Hi @dpoettler
I convert your issue as a discussion as I don't think it relies on a core issue.

The reason i think its not booting into the program at all was because i made a for loop that activates every pin because i thought the pin definitions might be wrong.

First remove this code. The pin definitons is automatically generated so I doubt any issue there.

It seems you used a custom board? Are you able to do something with your hardware before?
Did you try to debug to see where it stuck?

Ok you add it here #2830

Anyway since that an other contributor add a specific board in the same variant folder and it works:
#2851

So my guess is the clock config is not correct.
Please try to debug.
