Hi all :
Has anyone brought up Hafnium on Raspberry Pi 4 board ? I tried but failed by the following steps:
1.Make the Hafnium RAM disk with aarch64 build Pi4 kernel , RAM disk for Linux , manifest.dtb.
The manifest.dtb buildt by :
/dts-v1/;
/ {
│ hypervisor {
│ │ compatible = "hafnium,hafnium";
│ │ vm1 {
│ │ │ debug_name = "Linux VM";
│ │ │ kernel_filename = "vmlinuz";
│ │ │ ramdisk_filename = "initrd.img";
│ │ };
│ };
};
2.Copy bl31.bin hafnium.bin initrd.img to fat32 boot direction and configure config.txt . Power up my unit and got the uart error log :

Is there anyone can help me with this issue or share me the way to bring up Hafnium on pi4 ? Thanks very much !
