I may have found the correct procedure. It appears that in 2018.3 the process of selecting the "platform" is simplified and there may no longer be "platform repositories". Instead of the multi-step process outlined in SDSoC_Platform_v2018p2rev3p2.pdf (you Avnet guys should really update your docs), one proceeds as follows:
start from "New Project" GUI and select "New..." under "Hardware Platform"
Now under "Target Hardware Specification" select "Browse..." and navigate to the desired .dsa file. The hardware project name will be filled in automatically. Continue to create an empty project w/o the other hardware selection steps specified in SDSoC_Platform_v2018p2rev3p2.pdf.
As far as I can tell, the desired board support package is now loaded:
I am working on the reference design above and find that the latest xilinx SDK 2018.3 has interface and setup somewhat different from that shown in the associated pdf. Is there anyone that would be willing to help this newbie get this project set up or will I have to uninstall the latest xilinx sftwr and try and find the earlier release?
For example, instead of these two interfaces (from zedboard's pdf)
the new SDK provides a single interface
From here it the steps required to get the MiniZed board support are no longer obvious. There is no option at this stage to select "Manage Platform..." (1st image below from the zedboard pdf). Opening the repository gui in the 2018.3 SDK and adding a path to the zedboard provided "Platform" directory (2nd image below) does not seem to help either... the sdk still does not have the "mz_avnet" option (3rd image below from the zedboard pdf) appearing anywhere that I've been able to locate.
Can anyone help out?
This is not available in the 2018.3 new project dialog and the
