NXP PN553 NFC Controller driver porting on android 7.1.0 with iMX6D

Dear Sir/Miss,

I have a problem about NXP PN553 NFC Controller driver porting on android 7.1.0 with iMX6D.

Currently I can able to read NFC tag information but NFC module keep sending 3 bytes 61 23 00 every 10 sec as below:

01-01 00:06:45.494 709-862/com.android.nfc D/NxpNciR: len = 3 > 612300

And I got this error as below:

00:06:45.494 709-842/com.android.nfc E/BrcmNfcNfa: unknown opcode:0x23

Could someone help me to understand why NFC module keep sending 3 bytes?

Please see the full log file in the attached.

Thank you

Danny Lu

Regarding "61 23 00" NCI notification, it indicates NFC POLL discovery cannot be performed because of missing TVDD supply.

For your information, PN553 is not a mass market product. Please contact local NXP CAS team or local distributor for better support.
