STM32H747IX SystemClock_Config problem

I have configured the M7 clock to 480 MHz and the M4 clock to 240 MHz using the HSI as input. In SystemClock_Config routine the statement

__HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE1);

is crashing the STLINK-V3 with the error message

Error in executing 'step' command ...
Target is not responding, retrying...

I had a breakpoint at that line and activated it with the Step Into (F5).

First set speed lower....and see ds, whats max.:

Maybe: set at 200M + 100M , then go on. CubeMX should show you allowed speed vs scale and wait states.
