STM32L071RB RX Halt Issues

Itamar Eliakim · ‎2022-04-29

Hi,

We have been experiencing severe issues with RX UART on STM32L071.

The RX bus stops receiving data while running, and the only way we could recover from it was to initiate the UART back again which probably clears the registers.

Is anyone familiar with the issue?

We could not find anything in Errata.

Thanks.

Do you handle overrun error?

Thanks @Community member !

That was the issue.

I've disabled the overrun in CubeMX and everything works as expected.
