Hello,

It's recommended to use the latest version of STM32CubeProgrammer tool.
Please refer to the application note AN4938 "Getting started with STM32H74xI/G and STM32H75xI/G hardware development" for HW recommendations / power supply (section 2 Power supplies) as well as debug connections (section 6 Debug management).

hi

sofLit,

i check every thing, but its not the power or the connection. i solved it by connecting the ST-Link VCC to the board VCC. when i connect the external power then i am having the problem.
