Errata 164 and 191 on nRF52840 rev1

[Andrzej Kaczmarek]

Hi,

I checked erratas for nRF52840 rev1 and #164 is gone but #191 is still there. Can I have both #164 and #191 active in my code and it won't cause problems on either engineering or final chip revisions? Or better I should detect chip revision in runtime and apply erratas selectively?

Best regards,
Andrzej

Hi,

 

It is strongly recommended to develop on the latest revision now that nRF52840 is in production.

Erratum #164 was only present in nRF52840 engineering A (Fixed in engineering B and newer), while #191 is present in the from engineering B to the production ready variant of nRF52840.

If you're using the Softdevice, both of these will be handled there, based on which SoftDevice version you're using.

 

If you are developing/using a proprietary or 3rd party radio stack, I would recommend only implementing erratas/workaround for revision 1 (the production release of nRF52840).

 

Best regards,

Håkon
