Hello, Ajish,

Sorry, that documentation is for Gaisler's RTEMS version that is not
yet merged to RTEMS and has the driver manager.

You can find the older documentation here:

You will need to register the apbuart driver using:
"apbuart_register(&amba_conf)" as described in the above document.
Using the apbuart driver concurrently with the regular console
(printf...) may lead to problems....

Alternatively, you can edit the console code so it stops appending the
'\r'. I think you can do so by editing the following file:
and changing the line 146 from "apbuart_outbyte_polled(dbg_uart, c, 1,
1);" to "apbuart_outbyte_polled(dbg_uart, c, 0, 1);"
