Hello, This is Jena.

 

Battery management studio encaountered an error.

Operation failed becase initial read of all data flash failed.

 

I was using it in the same way until last week, but not yesterday.

I checked the cable connection.

    I see the SEC1 and SEC0 are both set to 1 in your first screenshot, which means the device has been already sealed.
    You have to unseal the device before you get access to the data flash again.

    Hello Andy,

    Thank you for answer.

    Sorry, I did not understand.

    What are the meanings of sealing and  unsealing?

    The gauge is in secure mode. It will deny all requests to read dataflash.

    Please unseal first. The technical reference manual has a section of seal and unseal you can reference.

    Thanks!
