1. you need to confirm that you make everything OK on MX, especially clock configuration and correct pin nodes for usart.

~ If you think everything you set is correct, you can reset your board after compiling and flashing the code. After that, you can see  information like

.

Be careful about the set of

After you configure the set of ai pack, HSE may change back to bypass clock source and clock configuration may change by mx itself, which will lead error for  SystemClock_Config.

2. reboot your board ***, and valid your network again.
