wiimx28 uart buffer size to small ?

0 votes

I think that some bytes are lost by the uart driver on Rx.

If i poll continuously : no problem.
If i stop and come back some millisecondes later : some byte are lost.

Using DMA or not doesn't seem to change.

Any idea is wellcom

You need to use software or hardware flow control. This will notify other side when it is ok to send and when it's not
