Hi
We are using cyclic dma in our uart driver (modified imx-uart.c) and ocassionally there seems to have data loss in receive side. Is it possible to use dma without RTS/CTS handshaking?
Common transfer characteristics are:
kernel version:3.14.28
Baud Rate: 1000000
Handshaking:None
Using Cyclic DMA
Best Regards
Ari
Hello,
To avoid data lost RTS / CTS handshaking must be used.
Have a great day,
Yuri
