The flow chart in the previous figure shows the basic application behavior. The
detail of the application varies depending on the configuration specified for the
SD-FEC IP core and example design. By
default the application has the NO_IO macro defined which disables interactive
functionality. The macro should be removed to enable the stdin and stdout functionality.
The Vitis software platform workspace is
configured to use the
MicroBlaze™
™ Debug Module or
CoreSight™
Debug for stdin and stdout as the hardware design
does not include a separate UART device or enable the PS UART.
When the interactive functionality is enabled all the design parameters, defined in the example design parameters table, can be updated using the UART terminal. A basic menu system is implemented where the parameters can be updated and repeated tests run.
