UART stops working after a while receiving

Hello, we use UARTB with a baud rate of 460800 bps. The remote device sends data packets of 20 characters (200 bits) with a frequency of 150 Hz. The VF61 does not send anything during this time. After a time of several hours the UART stops working, no more data is received and sent.
What could we do to fix this behaviour?

Hi @pulso ,

This could have many reasons. Can you elaborate a bit more on what is happening exactly. Does the Write and Read Call fail? or just do nothing? Does it help to Close the Serial port and re-open? Are other serial ports still working. Your baud rate is unusually high and we did not do internal tests with it (only up to 115200), so it could be that there is a HW issue with that…
