IVOR 1 while initializing HSM in MPC5748G

tejo2one — Thu, 06 Apr 2023 17:18:27 GMT

I have a working code where I want to integrate HSM.

After calling HSM_DRV_Init, during SetInterrupt mcu is entering IVOR1 error ?

What could be causing this? and how to resolve it?

Hello,

and do you have NXP HSM FW programmed in device or custom one?

If yes, which version?

Best regards,

Peter

Hello Peter,

I'm working using Devkit of MPC5748G. Is there a separate process to get HSM firmware ?

please provide more information, thank you.

Best regards,

Tejo

Hello,

To get HSM FW the part must come from NXP factory with already preprogramed HSM FW.

Such part is not commonly available and need to be asked via sales / distributor.

So in order to use HSM you either has NXP or third party FW or you are going to develop it yourself, which will require access to very sensitive documentation.

Parts with HSM FW starts with KC6676x instead of SPC57xx.

Peter
