ping... Hi everybody, I found maybe a "bug": kernel 5.17 on at91sam9g25 running at 400MHz usart configured in devtree to "linux,rs485-enabled-at-boot-time" is RX disabled during TX. This would be OK, but when TX is done, enabling RX takes too long (sometimes up to 500us or even more), this results in not capturing data answered from remote. RTS signal switching direction works as expected just after last stop bit.
