I have a new Phytec MPC5200 board and I'm trying to figure out how to get Linux booting on it. I have the kernel all built and I want to use a NFS root file system. When I use u-boot to tftp load the kernel, it errors out loading the RAMDisk.
Who is requesting the RAMDisk be loaded, is this coming from the kernel or u-boot? Since I am booting from a NFS root I don't need a RAMdisk so I want to turn this off. I'm using OSELAS MPC5200-tiny-5 to build but I'll switch to another environment if needed to work around this.
