I have an STM32H747I-DISCO board that I am trying to bring up with the Tutti Frutti Demo. I have followed the instructions in UM3008 to program this as it appeared to be blank upon arrival from Digikey.
External loader was set to: MT25TL01G_STM32H747I-DISCO
Programming of CM4 with intflash.hex and CM7 with target.hex completed successfully.
After programming, the board does not display anything and LD10 just flashes red a couple of times and then pauses on green then repeats.
Power LED is good (green).
I am not familiar with these development tools so it is likely I'm missing something but whatever it is is not clear to me.
I have tried resetting both through STM32CubeProgrammer (V2.21.0) as well as hard reset on the board.
Power cycling the board does not help. LD10 just solid red until I connect up STM32CubeProgrammer at which point it cycles between green and red as described above. I have seen this is a common issue with this board but I have not found an actual solution to this yet. If this solution exists, can someone point me to it?
Fun note: I did try to have AI help me with a solution on this. While entertaining after the fact, not recommended for those easily frustrated as it sent me down dozens of paths while giving incorrect info on quite a bit. :)
