Secure Boot added time

Hello,

I'm currently working with a s32k312 MCU and will need to use the Secure boot functionality.

I have tried to find any indication in the documentation (HSE Reference manual etc.) of how much time this functionality would add to the boot-up time when enabled without luck. Where can I find information regarding this?

Thank you!

/Jonas

Hello Jonas,

In the S32K3xx DS, rev.7 you can find Section 6.5.3 Boot time, HSE firmware installed.

Table 8 provides the boot time of the S32K3 SBAF and Firmware initialization.

To obtain the total boot time, the corresponding user code verification time (Table 9) must be added.

 

Regards,

Daniel
