Run generate-zbm with the debug flag so that you can see what's actually happening and where the failure is.

Thank you!
Why this information not show at generate-zbm page, it should directly at generate-zbm page.
now i can generate ZBM file, i see there is 3 files, vmlinuz.EFI, initramfs, vmlinuz-..
why 3 files? what purpose of each file? what should i use?
