We upgraded from kernel v4.9 from the TI source tree to v5.10 (the SDK v8.02.04) and are seeing increased errors on on the UART between the AM33 and another micro. Either lost or corrupted bytes on data received. We are using 115200 baud without flow control lines.
Software, DTS and hardware have otherwise not changed. Our hardware design closely matches the EVM and we only have a couple peripherals enabled (2 UARTs, 1 CPSW port and a few GPIOs for LEDs and HW button.)
I have not yet compared on a logic analyzer vs received data in SW.
Are there any hints as to why serial error rate would increase with a kernel change?
