How to download FPGA program through JTAG?
 
Question
How to download FPGA program through JTAG?
Answer

FPGA program of ZYNQ is conserved on RAM, you should redownload it when you electrify the board each time. We could utilize platform cable USB DLC9 to download it, vivado version is 2014.4. JTAG interface of Z-turn board could be used to download and debug program of ARM and FPGA, ARM and FPGA are linked to the same JTAG interface, and it could be distinguished by ID number. JTAG interfaces of Z-turn board are as follow:


You could just use one string to link GND, no need to link NTRST.


When you link the downloader to computer, Xilinx USB Cable will show on device manager of the computer:


When the board is not electrified, the status led of downloader is red, it turns green when the board is electrified.


1. Utilize vivado 2014.0 to open mys-xc7z010-trd project, click Program and Debug ->Open Hardware Manager -> Open Target->OpenNew Target under the left Flow Navigator.




2. Constantly click “next” on the popup window--Open New Hardware Target, till it appears the “Select Hardware Target” dialog.



Choose xc7z010_1 under Hardware Device, click Next->Finish.



3. "Hardware Manager" window will be automatically opened, click program device->xc7z010_1 on the up window, directly click program to download the program on the popup window--Program Device dialog.




4. Download progress window will appear then:


When you download it successfully, the board’s D25 led will get light, dial U20’s switch 4 to L. Switch 1,2,3 can control the light’s on and off of the three -color led D34.

Directly link the JTAG interface to CPU, there are no elements on connection during the progress. If it couldn’t be downloaded, please check:

1. Whether the linked cable between downloader and board are correct?

2. Whether the downloader could be identified on PC?

3. Whether the status led of the downloader is green when the board gets electrified?

4. Re plug USB cable of the downloader, electrify the board once again.
