I have boards with stm32f429 and rs485 driver, all running on freertos. When 4 boards are connected by rs485 somtimes one board is not communicate, other 99% time all is working great.
When I switch power off and on of this board problem is still exists. After some time board works again.

Whether it is possible that errors during data reception uart persist after power is removed?

Sorry for my English.
