ZYBO LED demo not working


Question

I am new to FPGA design . I have bought Zybo Z7-10 board and tried the LED demo given in this link" https://reference.digilentinc.com/learn/programmable-logic/tutorials/zybo-led-demo/start"

but i have the following questions about the demo . 

1. The board has only 4 LED and i have one PMOD with 8 LED . How to map the IP to this two different LEDS ?

2. Also the T20 pin given in the example serves for HDMI port in the xdc file , then how we can map the same in LED pins?

3. In 2019.2 version i am not able to find launch the SDK option then how to execute the same example.

Hi @mainak,

I would instead use the Pmod GPIO IP, https://github.com/Digilent/vivado-library/tree/master/ip/Pmods/PmodGPIO_v1_0, since the tutorial you linked is for WS2812 styled LEDs, not the on-board LEDs or the Pmod 8LD. The on-board LEDs you can control through the block design as explained in this tutorial here (or through HDL).

The tutorial you linked is also for the original Zybo and not the Zybo Z7-10 which are different boards and will have different pinouts.

The reason you do not find launch SDK is because Xilinx got rid of SDK in favor of Vitis starting in 2019.2. The second tutorial I linked walks you through how to use Vitis instead.

Let me know if you have any questions.

Thanks,
JColvin
