Hi Geert

That looks like a race condition between timeout handling and actual completion
of the DMA?

Sorry, I don't know exactly what you mean.
We use the baudrate of 38400 for all. (ttySC0, ttySC1,ttyUSB0,ttyUSB1).

The transfer works normally for a while before the warning message isoutput.


Thanks and best regards
JINSO/Truong
