Any updates?

I'd like to add that it's listed as available on https://docs.nordicsemi.com/bundle/nwp_057/page/WP/nwp_057/prod_sec_features/dev_features_54L.html

You said hardware support is there, software support not yet. Why don't you flag it in the list, just like

Authenticated Debug

HW supported¹

¹ Currently not supported in nRF Connect SDK.

It gives the impression, that the feature is ready to use. We are currently waiting for the device attestation feature as we dont want to ship without it as adding it later might be a risk.

No, In practice it refers to PSA Attestation. The hardware support is there in the nRF54 series, but software support is not yet ready (though as mentioned it is planned and will come).

Hi,

lists

Yes

is that something different then PSA Attestation?

Hi,

PSA Attestation is not yet supported on nRF54L, and this is also why the TF-M: PSA template sample does not yet list nRF54L as supported. Support is planned, but I cannot say when it will be ready.
