Problem Creating Std File (Mifare Desfire EV2)

[Gabriel Augustin]

Hi,

i am successfully creating Files on Desfire EV1 cards. with the command CD and a length of 7 bytes.
When i try the same command on EV2 cards i get 7E length error.

Should the command length be different with EV2 Cards or is there another problem?

Thanks in advance!

It's possible that the command length needs to be adjusted for EV2 cards or there could be another problem causing the error. To troubleshoot the issue, you might want to check the documentation or specifications for EV2 cards to see if there are any specific requirements or differences in command length compared to EV1 cards. Additionally, reaching out to the card manufacturer or their support team could provide valuable insights and assistance in resolving the issue.
