Hi,
I'm using UART1 and DMA with uart.c and uart.h ChibiOS libraries.
I have a problem: the function rxend is executed only at the first reception of a frame.
I tried to enable the circular dma mode for rx but it didn't work.
Why? Could someone help me?
In attached there is an abstract of my code ...
