STM32F4 with HAL drivers – Recive data doesn't work

Hello,

I am writing to ask about the possibility of an error.

I have STM32F429ZTI Discovery board and FreeFRTOS with HAL driversrunning on it. I would like to implement communication via serialport (UART5 in my case). The problem is that i can't read any data.

I can send data and everything is ok but when i want to recieve datanothing happen.

I find out that function „HAL_UART_RxCpltCallback�? in not called. Iknow that Hardware is OK, because i have other project on this boardwith standard liblary and I can send and recieve data.

At the bottom I include my code.

If anybody know what it could be I will be very happy for answer.

Thanks
