how to do internal loopback test for uart in bf-561 ?? Please do help as soon as possible....
There are a couple of UART examples available in the VDSP directory. You can check out the same.
In the path, ...\Analog Devices\VisualDSP 5.0\Blackfin\Examples\ADSP-BF561 EZ-KIT Lite\UART RS-232 HyperTerminal (C), there is an ADSP-BF561 UART Example Project which illustrates autobaud detection and UART polling and interrupt operation.
In the path, ...\Analog Devices\VisualDSP 5.0\Blackfin\Examples\ADSP-BF561 EZ-KIT Lite\Drivers\UART, you can find a driver based code called UARTExample which demonstrates how to use the UART device driver in talkthrough or echo mode.
For internal loopback, you should set 'LOOP_ENA' bit of the UART_MCR register. Refer HRM for more details about this bit.
