Hello Dear Everybody,
i have a new question about Zybo z7 20 with HDL Workflow Advisor. I use the Instruction for a Zybo:
https://se.mathworks.com/help/hdlcoder/examples/define-and-register-custom-board-and-reference-design-for-zynq-workflow.html
I have done the Step 1-9 of Set up the Zybo Board. But as i try with step 10 with the code h = zynq(), i get a error message from Matlab, and after switsching the Board on and off, the same problem comes. This rpoblem leads to unsuccessful execution of step 4.4 in HDL Workflow Advisor
"Cannot connect to "Zynq hardware". Details: Could not connect to the hardware over Serial Port. Check that USB cable is plugged into 'USB-to-UART' port of the hardware and the power switch is turned on. If this error persists, switch off the hardware, wait for 10 seconds, switch on the hardware and then repeat this step."
Does anybody have some solution for this problem? Is the Zybo z7 20 not supported from Matlab? i will be very appreciative. Regards Qian

Hello Li Qian,
I am not sure if the Linux Image that you downloaded in step 8 will work for this particular board; then again, this could just be a very basic connection problem between your PC and the board.
Please follow the troubeshooting steps here: Why can't I connect to my Xilinx Zynq or Intel SoC platform?
In particular, opening a serial connection using PUTTY would be helpful to see if the board boots Linux correctly.
