Hi freescale team,

            Thanks for your support.Now i am not getting any hab events

when i run hab_status command in u-boot.Here i applied patches from

following links.



In those links there is command called hab_auth_img .Curretnly it was

giving *hab fuse not enabled *(since i didn't made SEC_CONFIG fuse as



For testing purpose i made return value of the function which checks

SEC_CONFIG *(this function checks SEC_CONFIG fuse and returns TRUE if it is

closed otherwise FALS function:is_hab_enabled)* fuse status as TRUE (made

return 1) .That time *hab_auth_img *command is dumping IVT,CSF ....and they

are looks fine and it is entering to *authenticate_image *function in ROM

and strucking at that point.


Is this function checks SEC_CONFIG fuse internally?

This failure is because of not making SEC_CONFIG as closed?

Can blow the fuses now?


Thank You


With Warm Regards,
