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.
