3, lychee sugar HAX development board use:

3.1 Routine application

Method 1: Write the BIN binary file to the SD card. Power on loading;

Method 2: The Vivado project compiles the generated .out file and downloads it via JTAG;

Achieve the effect:

The LED light is constantly flashing. The other one is controlled by the button.

The process is as follows:

1) New project under ISE:

2) Instantiation

3) Launch SDK
