Hello,
I'm trying to read NTAG213. The read is successful for pages below 16.
I'm reading 4 pages block with READ (0x30) command. If I read a block starting from page 15, page 15 is read correctly and then the rest of the data is from page 0, 1, 2.
If I try to start reading from page 16 and above, I don't get any reply from trf7970a, and reading timeouts.
The function that reads block sends the following sequence:
8F 91 3D 00 20 30 [BLOCK_ADDRESS]
8F 91 3D 00 20 30 0C ------------------> OK
8F 91 3D 00 20 30 10 ------------------> NOT OK
For pages bellow 16 I get write interrupt after ~0.53 ms, send command to reset FIFO, and then get read interrupt after ~1.5 ms
I don't get read interrupt if BLOCK_ADDRESS >= 16
I have two tags, and I can read the content of a tag with NFC TagInfo app, thus I think it means no pages are under password.
We are using custom board and tms320C28xx microcontroller.
