Dear all,

I'm using CLRC663  with STM32 for my project.I want to detect all types of tags i.e Type A,B,F and V.The example i followed is NfcrdlibEx4_MifareClassic.I have enabled all the necessary macros for all types of tag.But i dint get type B,F and V other than Type A.I have changed only the driver file so as to work with stm32. 

Also I tried the same NfcrdlibEx4_MifareClassic example in the CLEV6630B v2.0 development board and i got it working for all tag types.But in my project ,it dint work except type A. The difference between my project and development board is only the MCU but the reader IC is same.

Whenever type B,F and V tags  are shown in the field,CLRC always return "No Tech Detected". It only detects type A tag.

when i debugged the firmware, i found out that only "TX-IRQ" sets for type B,F&V and "RX-IRQ" does not set. Whereas for Type A both "TX-IRQ" and "RX-IRq" set.

Could anyone please help me out in this .
