Restore the MIFARE DESFire EV2

[ekain_cuesta]

Hello,

I am using the OM27462CDKP developing board and now I am trying to run the extended examples and I run the PN7462AU_ex_phExMfCryptoEC but now I can't return MIFARE DESFire EV2 card to default. How can delete the things that example create on the card and restore to fabric version?

Thanks

Hi Ekain Cuesta,

Hope you are doing great, as you may know the information about DESFire EV2 is secured under NDA ( Non disclosure Agreement) this means that all the information, tools and supports should be delivered using secured communication channels and only with customers with NDA. despite you having an NDA this community is not the place to share that kind of information,  so I am going to give guidelines and reference to the full datasheet.

in order to format the card, you can use the FORMAT command, this command is explained in section 6.4.4.2 in the data sheet or the command structure in 7.3.2. you will need to be authenticated with master key to app 00.

Have a great day !
