NTAG Plus: Can read session reg, but not memory

Hi all

 

I'm trying to bring up my own board with a NT3H2111 NTAG Plus.


I can read the session registers, but nothing else.

I have attached two logic analyser snap shots. One is showing the session register access that is working and the other a read from block 0x04 from the memory. As you can see, the second slave address is not acknowledged and then the communication stops.

I have not written to any of the registers. But using the "Connected Tags Explorer" demo, I can read the memory and registers. I cannot find anything wrong anywhere.

Is there a simple thing I'm missing?

Kind regards, Claus
