STM32G4 TIM2 Output Compare No Output internal output state reading

Hi to all, i'm using the TIM2 channel 1 configured as "Output Compare No Output" with mode "Compare on match" and i need to read on the fly its internal logic state as it was a normal output compare with GPIO output.As far as i understood the related...

i did purchased a demo board stm32h750b-dk Demo Board, and i use USART1 ,Tx -PB6， Rx- PB7. it works well. no issue at all. but i need use USART2, Tx-PD5, Rx -PD6 . it no function at all. all setting - baud rate and other same setting.No idea what wrong.
