To use your custom board with our full Zynq hardware/software codesign workflow, you will need to complete the following tasks:
1) Build a custom Linux image from the MathWorks Buildroot GitHub repository, as explained in the following MATLAB Answers post: https://www.mathworks.com/matlabcentral/answers/880703-how-can-i-create-a-custom-linux-image-for-my-custom-board-to-use-the-zynq-workflow-with-matlab-simul
2) Obtain the board files from the vendor to register your board part in Xilinx Vivado tool.
3) Create a custom reference design in Xilinx Vivado tool, and export this block design to a TCL script.
4) Create all necessary plugin and definition files to register your board & reference design files with HDL Workflow Advisor in MATLAB.
NOTE: The above tasks are outside the scope of MathWorks Technical Support. What HDL Coder provides is the capability to allow you to import the custom Vivado design into HDL Coder workflow, and define a custom Reference Design, so HDL Coder can generate an IP core and insert it into the custom Reference Design for faster design iteration.
MathWorks Consulting Services may be able to assist with these tasks: https://www.mathworks.com/services/consulting.html
Refer to the following simplified example which sets up a Zybo board for our Zynq workflow (using a prebuilt Linux image, vendor-provided board files, and the existing Zynq processing system preset TCL file to create the reference design in Vivado):
