ECC608 with USB kit is not detected #139

Closed vgottardi2 closed 2 years ago

vgottardi2 commented 4 years ago

The device is not found because the code checks dev_type (ECC108) read from the board against device_match (ECC508) set in configuration https://github.com/MicrochipTech/cryptoauthlib/blob/102d7fcfa2cc1671fddb814bf8079756f70f7109/lib/hal/kit_protocol.c#L166

I believe this is a problem with older firmware in the kit that is improperly identifying the 608 as a 108 combined with an update to the protocol driver in cryptoauthlib that is attempting to pick exactly the device that is specified. There should be an update to the firmware in the kit that will properly identify the target.

Which kit are you using?

vgottardi2 commented 4 years ago

It's an AT88 REV-2.0

@KalyanCManukonda Can you provide the AT88CK101 update instructions and updated firmware url?

AT88Microbase to be precise - http://ww1.microchip.com/downloads/en/devicedoc/doc8723.pdf Quite old
