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.

http://lists.denx.de/pipermail/u-boot/2014-June/181423.html

 

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

closed).

 

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,
