Embedded Coder Support Package for Xilinx Zynq Platform cannot connect the laptop to the Zedboard.

Hi all,

I have a project that needs to run a Simulink model on my Xilinx Zedboard. I am using "Embedded Coder Support Package for Xilinx Zynq Platform" in MATLAB R2022a.

Issue: After following the package setup to write the firmware to my SD card and booting the Zedboard with SD card, I still couldn't connect my laptop to Zedboard using "zynq" command in MATLAB.

After booting the Zedboard with SD card, the IP address of the Zedboard changed to "169.254.0.2" and the IP address of my laptop Ethernet was "169.254.18.76". The subnet mask is "255.255.0.0". The strange thing is that I could ping "169.254.0.2" on my laptop but couldn't connect to this address using ssh on Putty.

Does anyone meet the similar issue and can give me some help? Thanks!

Hello Yuzong,

our documentation says that "The development computer network connection must be on the same subnet as the hardware board". A compatible IP address must be assigned to the development computer network connection (in your case 169.254.0.x)
