MIFARE DESFire EV2 fails some unit tests #120

Open darconeous opened 4 years ago

darconeous commented 4 years ago

The MIFARE DESFire EV2 is supposed to be largely backward-compatible with the MIFARE DESFire EV1, however it is failing some of the existing integration tests:

This issue is tracking investigating why this might be the case and if it makes sense to address it.

Any news on this? Without this issue being resolved, there is no way to actually program the EV2 chips without the intrusive licensing process by NXP.
