linux SC16IS752 driver,Receive Line Status error
Last edited by paulenuta on Fri Nov 11, If I try without the intercept of the CTS state but with zc16is752. After this, every character written in the serial terminal will appear in the serial terminal as you were writing in the command prompt.
Tue Nov 08, If you enable any auto-flow-control feature, it will only send data from its FIFO to the wire if the flow-control logic tells it to. The second parameter in the read or write function is the internal register address, these are defined in the SC16IS I haven’t tested it, so I don’t sc16is75 if this change actually changes what I think it does.
Transmission and the reception done with interrupt technique 5. Select all uname -sr.

Context switch surely takes some time, but 25ms looks way too sc166is752 for that only; maybe a higher priority process -es is running. Mon Nov 14, But queued work is performed within 25ms after interrupt occurs. I’ve tried to play with the priorities and scheldule policies, but it also did not give the desired results.
It’s hard to tell where these 25ms come from exactly without doing profiling on your system. I 2 C data write and read operations 3.
In the testing script I read CTS state to avoid blocking, Thu Nov 10, 9: Sign up using Email and Linjx. As for the chip itself and it’s driver: But after this time, FIFO is overflowed and data lost bytes transmits in 26ms. Tue Nov 08, 8: Because at my setup auto-cts works just fine.
