Hello,
I'm using STM32H735G-DK board and I can't read device memory using ST-LINK Utility.
I wrote simple example with led blinking and it's correctly uploaded to flash by STM32CubeIDE - led is blinking. STM32CubeProgrammer can connect with ST-LINK and I see memory map but I can't select start address to write new program to flash or external memory (Start address window is locked). When I want to start programming, code is automatically written to address: 0x00000000
Stlink Utility can't connect to the device.
I read previous posts about H7 processors:

I've also checked if the power configuration is set correctly:Neither of these solutions work. My code:

Development on the ST_LINK Utilities ceased before the H7 was released, don't expect to work.
You're probably not going to be able to set addresses for .HEX or .ELF files, these contain their own meta-data describing where they live, from how you linked them. Only relevant for .BIN files
Flash needs to be erased prior to being re-written.
Flash is mapped at zero typically, also where Cortex-Mx typically start, as SCB->VTOR == 0 at reset
>>Neither of these solutions work.
Yes, different problem, where no connectivity at all is possible, and it looks like you bricked the board.
Double check the build addresses in the linker script (.LD), and vector table / entries points in the .MAP file, or dumped from the .ELF file.
Up vote any posts that you find helpful, it shows what's working..

Thank you so much!! I was able to run an example with ExtMem_CodeExecution from Stm32CubeH7
