Hello venkatesan,

you can port PN7120 to your android system, but you need to pay attention to the version of android, see here:

PN7120|NXP

-- Android patches for support of NCI based NXP NFC Controllers in KitKat (REV 1.0)

It contains the patch adding support for PN7150/PN7120 to the Android Open Source Project, version KitKat 4.4.4.

Best Regards,

Weidong

could not able to figure out issue in which layer,

HAL, libnfc-nci, JNI and Framework.

Hope the linux driver is fine.

Hello Venkatsan,

Please verify your i2c address in driver against the NFC controller i2c driver, both should be same.

or you can use i2cdetect utility for address verification.
