ATSHA204A is being using, not the ATECC508

[abilbaotm]

Hi.

I have the AT88CK590 Evaluation Kit connected via USB. But when running the tests the ATSHA204A crypto chip is being used. Is this normal? Can I always use the ECC chip?

Regards.

For example, When I run the ecc-test-main I get:

cd engine_atecc/
# ./ecc-test-main

When the tests are performed only the SHA chip light of the AT88CK590 is on.

Thank you for your time. Regards.

Seems that the crypto chip is actually well detected and correctly used. The crypto chip was not correctly configured.

It appears the root cause of the lights on the AT88CK590 kit being wrong is a relatively minor protocol oddity in kit_protocol.c where the "s:" prefix should be "e:" for the ECC508 device. However that string only drives the LEDs and not the addressing of the individual devices.

Yea @bryan-hunt I realized about that, the LED was wrong but the crypto addressing was good.
