Thanks, I made some progress. Now I'm stuck trying to specify the rootfs. I boot with the following arguments (full fork of your repository here [1]): console=ttyAMA0 mem=2048M devtmpfs.mount=1 earlyprintk rw init=/bin/sh root=/dev/vda I copied it from the command-line parameters that linux-system-foundation.axf uses [2]. And then boot with the raring image specified as the --block-device in Foundation_v8 like: $ ./Foundation_v8 --image linux-system.axf --block-device raring-arm64-rootfs I built my linux-system.axf from my kernel tree using your Makefile. Unfortunately, instead of the sh prompt, I get: VFS: Cannot open root device "vda" or unknown-block(0,0): error -6 Please append a correct "root=" boot option; here are the available partitions: Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) I'm not exactly sure what went wrong: I made sure to compile my kernel with virtio support. My confusion can be summarized as: when I specify a file as a --block-device to the Foundation_v8 emulator, under which device node is it available to the kernel? How do I specify a proper root device? I tried reading through foundation-v8.dts, but couldn't understand much. Also, I didn't understand the part of your Makefile that deals with the filesystem: what is filesystem.cpio.gz, and where is it going to be used? Thanks.
