Updating MCUBoot OTA

[David]

I have found that you cannot update MCUBoot unless you also have the NRF Immutable Secure Bootloader, If i have this then i cannot update the Immutable bootloader.

Is there a way so that i can basically update every component on the Chip. Bootloader and Application?

Hi!

 

Is there a way so that i can basically update every component on the Chip. Bootloader and Application?

This is technically possible, but it's not a configuration we support as this kind of setup removes the root of trust, so it's not secure.

Updating the immutable bootloader shouldn't be necessary though, as its only function in this context would be verifying that the image is signed and unchanged.

Best regards,
