Boot from OTP

Hi Dialog,

Is there ANY way to get the BootROM to execute an application that is stored in the OTP?

I have seen notes that the mirrored mode is not supported.

What about the cached mode?

Are there plans to support these in the future?

Device:
DA1468x

Hi DLWAY77,

Hi DLWAY77,

Can you please indicate which device that you are using? Is it DA14680/681 or DA14682/683? In case of DA14682/683, there is a tutorial available in the product webpage for how to implement secure boot. This feature ensures the firmware image running on the DA14682/683 can be trusted and is free from tampering. This is performed by the Secondary Boot Loader (SBL) stored in the OTP. Please check it outDA14682 / DA14683安全引导教程. Additionally, may ask if you have product based on DA1468x product family?

Thanks, PM_Dialog

We are evaluating DA14681.

The WLCSP package is best for our needs.
