The Segger RTT viewer can be used to display log messages received from the target. The base
address for the RTT block placement is 0x1fff8000. It is recommended to use a search range of
0x1000 around that base address when using the RTT viewer.

## Fixed
- Fix `embedded_io` UART implementation to implement the documented contract properly.
The implementation will now block until at least one byte is available or can be written, unless
the send or receive buffer is empty.
