STM32Cube Bug? Nucleo-F746ZG doesn't work when HSE is enabled as PLL source, How to fix?

I'm testing STM32F746GZ for our new project now. I use STM32CubeMx V4.20.0 with FW_F7 V1.6.1 generated a empty project for Nucleo- F746ZG board as MDK-ARM V5 project. There was no any problem if I use HSI as system clock PLL source(default).


However, after I enabled and switched system PLL clock source to HSE in byPASS mode(default 8MHz MCO on Nucleo-F746ZG), it stopped working inside "SystemClock_Config()".


My case is very easy to be duplicated if you have a Nucleo-F746ZG board.

I believe STM32Cube has a bug for running HSE on F7 processor. It would be very appreciated if any body over there can help fixing this issue.


Thank you in advance.
