STM32MP157 Tx Stops When Using Serial With Python

[potato_2]

Custom board using MYC-YA157C, with Ubuntu 18 on it

I'm using RS485 serial communication using python, it communicates well at first, but after a few hours tx stops

Uart7 is in use and TX is stopped at tx:2875680

I checked that the Python file is still running

Can I see where the problem is?

Hello @potato_2,

 

Did you have a look into the following wiki article : Trace and debug scenario - UART issue ?

I would focus on chapter 3.

BR,

Christophe
