PN7160 I2C EVK no NFC tag detected

jjins — Fri, 01 Dec 2023 05:43:18 GMT

I ran pn7160_nfcDemoApp_poll.
tag is not detected

When I checked with spy, the PCD doesn't seem to respond at all and the RF field doesn't seem to be turned on. What should I do?

Hello @jjins

In principle, using the 7160 EVK board based on AN13287 porting should work. And I did a test on Raspberrypi+PN7160 EVK, everything works fine. Therefore, it is recommended that you check your system by referring to chapter 5 of AN13287. Or do you have the same error as below?

Error was resolved with a patch. Please look at the log I posted.

I followed an13287 and it didn't work, so im asking.

Hello @jjins

Could you share how to generate such log "pn7160_nfcDemoApp_poll.txt"? That is to say, what command did you execute that produced such a file? I'll export the same log and compare it with yours, maybe find where is the problem.

The following values were set in libnfc-nci.conf
APPL_TRACE_LEVEL, PROTOCOL_TRACE_LEVEL

There is also a printf I added in pn7160_nfcDemoApp_poll.txt

Hello @jjins

Comparing the logs of running nfcDemoApp_poll, there are two variables in your log that are not enabled, NXP_T4T_NFCEE_ENABLE and MIFARE_READER_ENABLE. Is this causing your device to not work? Please check.
