Contribution description
The UART self-test using a TX-RX-loop fails on
master. Luckily it's not a bug in the UART driver, but just a timing issue betweenuart_writereturning and the HW triggering the RX callback. This PR fixes the test by adding a 1ms delay between TX and RX buffer check.While at it, I also improved the error handling and reporting in the test.
