I tried the Secure Boot of I.MX 8mm. When looking at the information, I saw "config_secure_boot" and "config_imx_hab", and there were Guide documents under U-Boot/DOC: doc/imx/ahab/  doc/imx/habv4/

 

What is the difference between HABv4 and aHAB?

Is there a more detailed explanation document?

Hi @callme_friend,

I hope you are doing well.

CONFIG_SECURE_BOOT option is replaced with CONFIG_IMX_HAB in the newer BSP using the below commit.

 
HABv4 and AHAB are both different secure-boot concept.
 
AHAB is new secure-boot concept used in i.MX 8/8x/8ULP/9x family of applications processors
&
HABv4 is available in i.MX 50, i.MX 53, i.MX 6, i.MX 7 series and i.MX 8M family of applications processors
 
Please refer to the documents.
