Booting-IMX8MM-Mini-board-using-V2024-04-version-Yocto-Scarth

Hello NXP,

I'm trying to boot the IMX8MM Mini Board using V2024.04 U-boot Version.

I'm facing issue while signing and authentication.

Currently I'm upgrading to the Yocto Zeus ( u-boot v2020.04 version and Linux kernel 5.4.70) to (Uboot-imx v2024.04 and kernel 6.6.26) Scarthgap.

before this I upgraded to Krikstone u-boot v2022.04 and linux kernel 5.15.70.

I booted the U-boot v2022.04 successfully. while booting kernel i faced below issues

Issue: CSF Header Authentication failed. and some time IVT not found.

In Ubootv2022.04 source code Kernel load address was changed from 0x40480000 to 0x40400000.

Later I changed the Kernel load address to 0x40480000 in u-boot. Later its booted the kernel.

Now i'm trying to boot the u-boot v2024.04 version.

I'm using cst-3.3.1.tgz version for signing the image.

spl hab block block correct size how to find it ?

sld hab block: address was modified 0x401fcdc0 to 0x401fadc0.

im not able to boot the v2024.04 what is the correct csf offset to use to sign and authentication.
