Dong Yang

Dear expert

Our customer would like to know how much time will be added during boot if we use J6 secure boot with HS device. Does TI have any data or estimation?

Hi Dong,

As per TI estimate the boot time impact should be around 100 ms for secure boot.

What are you talking when you say 100ms? u-boot and kernel?

Dong,

This estimate is for TI's SBL which is used by Vision SDK, not on the linux side. The break up is given below:

                                 Time(ms)
Efuse driver/BCH 5
Hashing     22
ECC Verify               64
Misc.                         4
Delta                         95

Rishabh
