Ramdisk Image

A ramdisk image is required to boot. A single ramdisk image is included as part of the SDx environment IDE installation. If you need to modify it, or create a new ramdisk, follow the instructions at wiki.xilinx.com.

If PetaLinux is used to create Linux boot files, the ramdisk is included in the unified boot image file, image.ub, rather than as a separate file.

Whether you provide an image.ub file, or separate Linux boot files (device tree, kernel, ramdisk), you will need to define the sdx:imageData attribute of the <sdx:image> element to specify the platform folder that contains these files.

Sample xml description:

sdx:imageData="image"
