STM32F429 HAL_UART_Receive_DMA problems

Hello,
I have an issue to which I cant find a solution.
I'm working with different UARTs, and I find a problem. If I use them using HAL_UART_Receive_IT, everything works ok, HAL_UART_RxCpltCallback is called, etc etc.
But when using HAL_UART_Receive_DMA, some UARTs work (ie UART5), but some others dont work, and I cant figure out why (ie: UART6, UART7).

Does anyone know something about this issue?
Thank you very much.
Fernando
