Getting 6E00 while using DESFire AES authentication with SAM AV2

dev-support — Mon, 06 Apr 2020 14:35:01 GMT

I'm using SAM AV2 for DESFire EV1 personalization. When I'm sending SAM_AuthenticatePICC sequence, I'm getting 6E00 (Class not supported) error from DESFire EV1.
I'm following "AN1826 – MIFARE SAM AV2 – For MIFARE DESFire EV1" and "P5DF081 – MIFARE Secure Access Module SAM AV2".

Logs:

Hi Tithi Patel,

Hope you are doing great, as you may know the information regarding Mifare SAM and DESFire, is secured under NDA ( Non Disclosure Agreement) which means that all the information, tools and support should be delivered using secured communication channels and only to customers with active NDA. this is a public forums where we cannot discuss secured information, my only recommendations here, is that you check that the SAM is in the Mode you are sending the commands, AV1 or AV2 mode, that the DESFire MK is the type you are using, and the correct values for the Keys in the SAM and the Keys in the DESFire.

if you keep having issues please let me know if you have any distributor that can help you in a secure communication channel.

Have a great day !

Jonathan
