NRF9160 Full modem firmware update when can CONFIG_FMFU_FDEV_SKIP_PREVALIDATION be turned off?

[JVantol]

It looks like even with the latest SDK 1.6.0, the full modem firmware pre-validation is turned off.

It looks like this is a modem firmware feature, so it would seem that the check should be a run-time check and should depend on the current firmware version, rather than being statically defined.

Is there a version of modem firmware that does support pre-validation? Could the SDK be updated to do the pre-validation if it's supported and skip if not? I would like to ship firmware soon, and I would like pre-validation to work once it's available.

Hello Joshua,

I’m honestly not quite sure if pre-validation is implemented to the modem firmware yet. But you could of course try it with the latest modem firmware 1.3.0.

If pre-validation is not supported, the function nrf_modem_full_dfu_verify will return with an error.

Regards,

Markus
