LS1028a reset fuses to '0' in development mode?

[mbourhis]

Hi,

I am currently working on the SecureBoot for my board.

During the step of 'development' or 'testing',

is there a way to reset or set to '0' the SRKH fuses, after they have been blown

by the command 'mw 0x01e80020 0x2' (write '0x2' in the SFP_INGR register).

Or maybe, is there a way to 'test' the SecureBoot without blow the SRHK fuses?

Thank you for your help.

Best regards,

Mikael Bourhis

There is no such way.
