I have managed to get talking to my maxq1065 chip. I have MXQ_Get_Challenge() and ECDSA_sign_secp256r1_sha256() working for the Admin keypair. But when I do the MXQ_AdminAuth I get back a 0x1000 (unspecified error).
Here's the exchange:

The KeyPairAdmin is copied right out of the examples. Is there any way to validate that the signature is valid? Any idea as to what errors can lead to an Unspecified Error?
