Thingy:91 - EEPROM version identification

[Achim Kraus]

According the changelog Nordic Thingy 91 - Download - Hardware files - 1.4.0  the EEPROM was added for version identification.

However, reading the EEPROM from version 1.4.0 or 1.5.0 doesn't show a difference.

Is the idea to store the version identification canceled?

Hello, 

I have forwarded your question to the Thingy:91 design team and will update you as soon as I have an answer. 

Kind regards,
Øyvind

A small update. The eeprom is intended for HW identification, however, I'm not sure what the status is. Will have an answer next week. 

Kind regards,
Øyvind

Though it's more curiosity then a real issue; no need to hurry.

I'm happy, that the EEPROM is there at all and the most of it can be used for an application.

I was still not lucky with getting a v1.6.0 to test and the main benefit of reading the hw version would be to detect the v1.6.0 in order to omit the suspend of the 3.3V.

Any update?

Is that date in the EEPROM used? Or is that idea withdrawn?

[Øyvind]

Hello, no I did not get a response and then it went under my radar. 

Will provide an answer by end of today or tomorrow.

Sorry for the inconvenience. 

[Øyvind]

Ok, so the EEPROM was not put into use before v1.6.0 according to our HW team. In v1.4.0 and v1.5.0 the FICR address is empty. 

Were you able to get your hands on a v1.6.0?

[Achim Kraus]

No, unfortunately, ordering a Thingy:91, it was more a lottery, which version you get.

Anyway,if It's used now fro newer Thingies, then the question is answered for me.
