I reduced the kernel image to 90MB and the initramfs to 80MB. In the non root cell config file, i declared a memory region with size 0x5fff000 (~1.45GB) (send in attachment), and even when i issue "jailhouse cell linux ultra96-linux-demo.cell Image -d inmate-zynqmp-zcu102-2.dtb -i rootfs.cpio -c "console=ttyS0, 115200" -k 4", it still gives me the error of no space found to load all images.
