Hello, all!

I'm testing ATECC508A using AT88CK590, and I'm trying to write my own private key.

I set slot 0 as follows:

slot_0_config

 

Now, I locked the configuration zone, and now am trying to write to this slot before locking the data zone.

write command doesn';t work, apparently because it's defined as holding ECC key. 

So I tried writing with privWrite:, and it still doesn't work.

the command I used was: 

46 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

 

)the key is just 0000....(

This still does not wortk and retrurns 0x0f.

Anybody have any idea why this might not work?

Thanks!
