regarding part number i can't give answer...

Tools: cc1310, clrc633, code composer studio and card desfire ev1

Can this problem be due to the part number?

Hello All,

I have the identical problem.

Cards are overseas sourced and using MF3ICD41 ( so they say, but as per NXPs Tag info app. ).

A few also came from a source at Amazon.com. Card are only good for CSN once this occurs.

Any native card command results in PCB 0xF2 followed by RC 0x01 ( 0xF2 0x01 )

Cards operate mostly okay other than this, as long as you don't run 0xFC of course.

btw: system is a TI micro driving a 663 frontend.
