Zynq 7000 Emio control tricolor lamp debugging project
no vote
<span style="color:#676A6C;font-family:"font- size:15px;font-weight :600;background-color:#FFFFFF;"> Describes how to lead out GPIO through Emio and control three color light d34. This project is different from the previous example. The previous program runs in the internal RAM. Before power on, the internal RAM can be used. No additional program is needed to initialize, but the external DDR can only be used initially. This program is fsbl (first stage boot loader), fsbl It is not only responsible for initializing external DDR, loading app (application) into DDR to run, but also responsible for downloading bitstream to pl. Fsbl doesn't need to be written by ourselves. There are fsbl projects in SDK. Fsbl projects can be generated directly with SDK.

The first project of zynq7000, HelloWorld complete program project
no vote
This example realizes printing "Hello world" from the serial port, which does not involve the development of FPGA, but zynq's arm and FPGA development are very close, and you can be familiar with the FPGA development environment through HelloWorld. This example will explain how to build a project in detail. The later examples only explain the important parts. If you are not familiar with the operation when reading other examples, you can refer to this chapter.

Zynq7000 controls led on and off through GPIO
no vote
Zynq's GPIO can be led out to PS pin through Mio, and can also be led out to pl pin through Emio. The PS terminal can lead out 54 gpios, and the PL terminal can lead out hundreds of gpios (depending on the specific model). The GPIO of this example is led out through Mio to control LED D29
