[ driver/komodo.ko -ot guestimg/guestdisk.img ] || guestimg/cptoext2.sh driver/komodo.ko guestimg/guestdisk.img /lib/modules/komodo.ko[ -f guestimg/guestdisk.img ] || cp raspbian.img guestimg/guestdisk.img
[ -z "piimage/piimage.img piimage/config.txt" ] || guestimg/cptofat.sh piimage/piimage.img piimage/config.txt guestimg/guestdisk.img /
Usage: guestimg/cptofat.sh file image dest
guestimg/subdir.mk:14: recipe for target 'guestimg/guestdisk.img' failed

It's hard to be completely sure without knowing what files you have on your filesystem, but it looks to me like this might be a bug in guestimg/subdir.mk:15. Both piimage/config.txt and piimage/piimage.img are out of date, so it is trying to copy both of them into guestdisk.img using cptofar.sh, but the script only supports copying a single file at a time.

These scripts are quite flaky -- they are written in a very roundabout way using pure-userland utilities like e2cp and mcopy in order to work on WSL, but if you're on Linux it would be much faster just to make a loopback mount of the partition and copy the files in directly. The end-goal is to take a Raspbian image, copy komodo.ko into the ext2 filesystem from where you can later insmod it, and copy the modified config.txt and piimage.img in the FAT boot partition so that the monitor runs in secure world at startup prior to booting Linux.

Also: this isn't a real-time support forum -- this is a GitHub bug tracker for a research prototype, so you shouldn't expect fast turnaround.
