Hi,

Based on my knowledge, when adding a new component affect the HPS (such as adding the extra EMACS), you will need to recompile everything, Platform Designer, Quartus etc.

Have you tried running the reference design for the first time to see if it is running successfully?

      Yes, the project works fine before I add the extra EMACs. Are there any changes to uboot/Linux that need to be made? Do the Device Tree Blobs (DTB) need to be modified?

      Hi,

      Yes, since the changes are affecting the HPS, the preloader, uboot , dtb need to be recompile to take affect of the changes made.

      May I know are the project files that you use already prebuild?
