Hello, 

I have some trouble to control uart communication with uart port not usart port of STM32F429,

I can communicate tx/rx with USART port, even in interrupt mode,

but when trying to communicate rx/tx with UART port(UART7), I can't see any progress in HAL_UART_RxCpltCallback & HAL_UART_TxCpltCallback function, why ?

please help to let me know the method with example, 

I need to use the interrupt service routine to control rx/tx data, 

thankful for your support in advance,

thanks.

Tightly configured examples will need more specific details on the board in question, the pins used, and clock sources.

Perhaps look at some of the available examples in the HAL trees for direction

STM32Cube_FW_F4_V1.21.0\Projects\STM324x9I_EVAL\Examples\UART\UART_Hyperterminal_IT

For interrupts check the plumbing from the IRQHandlers and NVIC, and into the HAL and out via the callbacks
