Posted on December 18, 2017 at 20:19Ok, 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:
Mon Dec 18, 2017 21:11:11: Connected to ST-Link/V2-1 [SWD mode 1800 kHz] [Access port: 0] Firmware V2.J28.S18 (Probe no: 57175540)

Mon Dec 18, 2017 21:11:21:
Mon Dec 18, 2017 21:11:21: Exception occured at: 0x20000280
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 )
Many thanks
