Hi,

We are planning to work for a secure Boot on iMX8MQ.

For secure boot, we need to program the fuses on i.MX8MQ(processor) and as per our understanding this is a one-time programmable process.

So in the development phase, we would require process steps where
1) A method by which we can reverse the false written fuses? As per our understanding this is not possible. Kindly confirm.
2) An EVK which contains the socket-based processor, whose processor chipset can be replaced. Request to provide the reference where such EVK with processor socket for our development.

Thanks,

Nilesh Patel

Hi Nilesh

 

>Is there any method, to avoid processor damage?

I am afraid no, as blown fuses can not be reverted back.

 

Best regards
