Hello,
I made a very similar board to the Portenta H7M4 board. I used a slight variation chip, however I can't get it to take code. I am able to program it with STCubeIDE successfully and I can get an LED to blink.
However using the Portenta H7M4 as a basis for my board I can't get it to blink. It appears to be programming but can't get the code to blink using the STLink Programmer.
I tried programming manually with the st-flash utility and trying to change the default memory address from the STCubeIDe default (00) to the one use in Portenta. I have no luck with this.
Anyone can point me to something I might be missing I would appreciate it very much.
Help using a custom board with STM32H757XIH6 in PlatformIo or Arduino
If you made your own board, post here, unless you built a Maple or Maple mini clone etc
