Ok, I having more than a bad week regarding ST products.
I hit very new problem with Nucleo-H743ZI. Generated projects, example projects hang when flashing code to MCU.
with STLink utility, i can program it with hex file, but for some reason, IAR ARM does not want to flash it. It gives error after freezing loading code like this:

I try to different boards, reinstal newest version of IAR ARM, it gives same results.
Now i know for fact, i was working with H7 with older version, and did not had any problems, i guess this is newest version bug. But how to fix it ? Who to write to ?
Can any one dublicate this problem ? ( just any example from STM32Cube\Repository\STM32Cube_FW_H7_V1.1.0\Projects\STM32H743ZI-Nucleo\Examples\ dirctory )
