In case an image is updated after initial signing, use "ReSignBl" to re-generate aes hash and pkc pss signatures if PkcKey is present.For example: Define re-sign.cfg as below: PkcKey = rsa_priv.pem, --save; ReSignBl; Run command below to re-sign image: $ cbootimage -s tegra210 --update re-sign.cfg image image-re-signed
Is this to support the case where someone just dd's a new bootloader into an existing flash image? Why not just rebuild the flash image from scratch using existing features?
