My board is imx6q, now I want to sign the rootfs(in ext4 format), How can I sign the rootfs?
Can anyone give me some suggestion, or recommend me some reference? Thanks a lot.
what is “sign rootfs"? could you explain this more?
calculate the sha256 of the rootfs.
Could you please describe it more ? Like calculate the hash and store it in kernel image ? I have the same problem, but i can not find a solution.
Yes, kernel calculate the hash of rootfs, and the hash result should be stored in secure storage.
