SFI Via HSM

[Surya S]

Hello Everyone,

With STM32HSM -V2AE - 25

-> Flashed the firmware version1.0  for 10 numbers and will the remaining 15 counts supports to flash the updated firmware version 2.0?

-> If the firmware upgrade happened in field how does HSM support in that case.

 

 

Thanks In Advance

Hello @Surya S

 

You can do this if you encrypt the second firmware with the same encryption key and nonce files (used to program the HSM).

 

I hope you find this helpful.
