How to get the security firmware for the HSM

[Othmane1]

Hi,

I have used the DCF records to enable the HSM in my MPC5748G board but when i tried to run the "security_pal_mpc5748g" example from NXP i came to realize that there is no 'security firmware' in the HSM, so i wounder how to get it and how to flash it there?

Hello,

Security FW for MPC57xx devices is burn to device directly in the NXP factory. There is no possibility to do it afterwards.

Such chip has special markings and is produced only on request.

Unfortunately what you are trying to achieve will only work if you use your own HSM FW or some third party if there are ones available.

Best regards,

Peter
