Hi Timg236
Actually want to understand in secure boot mode enabled, while booting it will always expect boot files packaged in boot.img? if it expects boot.img as file then i have to keep the boot.img and boot.sig in boot partition correct?
In my case the boot.img gets created in build but further while creating the full sd card image (i.e. core-raspberrypi.sdimg) with boot, rootfsA, rootfsB and other partition, it unpacks content of boot.img in boot partition.
Another approach tought of, I have to name the sd card image(i.e. core-raspberrypi.sdimg) to boot.img and create boot.sig of it and copy in sd card as files is this the right approach, but this approach confuses as the sd card image size is approx 1GB and it is mention in document that boot.img cannot be greater than 180MB.![Image]()
