Hi.
We are trying to personalise NTAG424 tags following the data from AN12196 document. Currently having difficulty with writing the NDEF file using the example data (Section 6.8.2) (but with card derived keys). The following APDU log shows that we are getting a 91BE SW on WRITE file:
--> 00A4040C07D276000085010100
<-- 9000
--> FFCA000000

--> 91BE
The session keys were derived as:
ENC_SESSION_KEY = 78EE9EA87E59F1210693EFC4A9AA0FBC
CMAC_SESSION_KEY = 42CB1798A4F3F7A540F7D057CE029EDC
The Status word indicates 'Attempt to write beyond the file boundary as set during
creation' (NXP-NT4H2421Gx.pdf)
Any help welcome,
Tomasz
