Some questions about NFC Reader Library NDA-for-CLRC663

Hello everyone,

I am using the OM26630FDK develop kit to learn how to use NFC-Reader Library-v071300-NDA-for-CLRC663, and now I am encountering an issue where in the example 10 "MIFAREDESFire_CVx", only EV2 and EV3 cards are supported, and EV1's card reading fails.The relevant documents also show that only EV2 and EV3 are supported.

I used this example 10 to run and tested it with a blank card of EV1, and found that the masterkey could be successfully verified. Then, I could read "App creation DONE!", "App selection DONE!", and "Creating standard data file Success!", but there was an error while reading the data.

Due to historical reasons, we still need to continue developing EV1 related products. Can your support team provide examples for a series of operations on EV1 cards?

Or, based on the example 10 that only supports EV2/EV3, how can we make modifications to support EV1 and provide some constructive suggestions?
