BQ27Z561-R2: Issue with the authentication function

Maurizio Risicato

Part Number: BQ27Z561-R2

I would like to know if the TMR is correct or contains an error. I can't load the "authentication key", does the BQ27Z561-R2 device support this feature?

Hello Maurizio,

I believe this is a duplicate question as the one linked, we will let you know as soon as we have feedback on the original thread.

Sincerely,

Hi Wyatt Keller,
Shirish replied on the following link:
BQ27Z561-R2: Device Security - Authentication function with secure key.
I responded with further requests to seek an alternative solution.
I'm not familiar with the forum, but I think I don't have to repeat the questions that should be visible in the link.

Thanks for your time

Hello Maurizio,

I believe the questions are the same for both threads, or Shirish has just answered both threads.

Usually we try to keep one thread per issue so it is easier for others to search for, if multiple threads for the same issue are created it takes more of the team's time to filter duplicates so we can't answer questions as quickly.

Sincerely,

Wyatt Keller

Hi Wyatt Keller,

the questions are related to the same topic, but since until yesterday we had not reached a conclusion, so I connected to this threads by pressing the "ask a releated question" button in the link

https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/943522/bq27z561-r2-do-you-know-the-default-sha-256-key-of-bq27z561-r2?tisearch=e2e-sitesearch&keymatch=BQ27Z561-R1%20authentication#

to see if someone had come up with a solution 1 year ago (because even there the discussion had not ended).
Maybe I was wrong to proceed, however I think that now it can be closed or canceled, how should I proceed?

Should I press the "This resolve my issue" button?

Hello Maurizio,

That is okay, the questions just seemed like the same ones that Shirish was attempting to help you with so I thought they were duplicates.

Yes if your question is resolved for both threads you can use the "This resolved my issue" button to help us
