Hi guys

I am using the atsha204a for first time and I want to read the data what I have written in slot 0 so this is the step which I have used

1] Config Write – writing 0x80 0x80 0x80 0xA1
2]Locking Config Zone
3]Writing your 32bytes private key in slot 0
4]Locking Data Zone
and how to unlock the locked config or data zone

 

Regards

Pretty sure there was a recent thread asking the same question, and the answer was no - once it's locked, it's locked.

 

Which makes sense for a security product!
