Serial communication with Raspberry PI

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I am looking for help getting serial communication to work via the UART on either a Raspberry PI 3 B or a 3 B + that is running Fedora 29.  The kernel recognizes the UART as /dev/ttyS1 on these systems.  Data flows, but it is corrupted at random intervals.  This happens at any baud rate.  With these same two computers, everything works fine if I run Debian, which I really don't like.  So it is not a hardware issue.  I am thinking it is more of a device tree problem.

I also have UART to USB adapters that the kernel recognizes ad /dev/ttyUSB0.  When using these under Fedora there is no corrupted data.

I would mention that I also have Fedora running nicely on a Quad Core i.MX6 based Hummingboard2.  On that UART, there is no corrupted data issue.

For my project, I really would like to use Fedora and have good communication via the Raspberry PI UART.  Is anyone here successfully using the UART on the Raspberry PI 3 B or 3 B +?

One final thing to mention, I do not have the console enabled on /dev/ttyS1.  If I do enable it, I get the corrupted data when trying to log in or look at console output via a serial connection.

Any help would be greatly appreciated even if it just to tell me what to go read.

Thanks,
Will
