To clarify, most data doesn't arrive correctly. None of the data arrives correctly (unless by coincidence).

They're going thru a transceiver on the Device1 side: the TI ISO7721-F. On the Device2 side, it's just level shifters and I'm 100% confident that the Device2 hardware is correct since it's been used for a while with comms with a different device. Device1 and Device2 are less than a meter...

I have tried slower speeds, and it doesn't seem to change the behavior. Here is a link to the reference manual for the MSPM0. Thanks!

Hi all, I'm working on getting UART communication running between two devices: Device1: MSPM0 microcontroller Device2: Teensy 4.0 Both devices are configured for 115200 baud, 8 data bits, no parity, 1 stop bit (8N1). However, I’m encountering some strange behavior: If bytes from Device2...
