problem with programming the STM32H755iit

[Hans T]

I have a problem with programming the STM32H755iit

- Jtag gives an error

- DfuSe 3.0.6 Demo sees very few internal sectors, and hungs instantly

The SMPS is off, and I connected this like this: see picture

The CAP reads 1.0 volt

VDDLDO_1 = 3v3

VDDLDO_2 = 3v3

VDDLDO_3 = 3v3

PDR_ON pullup 3v3

It seems I cannot access the internal Flash memory

Anyone an idea why?

DfuSe demo is very old compared to the H7 design/release, arguably the development has been deprecated in favour of newer tools.

Try using the USB/DFU mode in STM32 Cube Programmer

Oke i wil try

I use the STLINK with this settings :

i use this STM32 ST-LINK utillity

The ST-LINK Utilities have also been deprecated in favour of STM32 Cube Programmer

I think this is a pity, but nevertheless it is the state of affairs.
