OM5577 kit with Beaglebone black and Android

[venkatesansubbu]

Hi,

We have system Beaglebone black with Kitkat OS running. I like to integrate OM5577 ie PN7120 NFC kit with beaglebone black and integrate with Android kitkat . The application note mention the same.

refer http://www.nxp.com/documents/application_note/AN11646.pdf

Do anyone build such a system?

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

Thank you for your reply.

we used the beaglebone black linux, it is working fine in polling mode.

wit the same configuration we ported to android lollipop 5.1.0 with release nfc.nci 3.5.0-LOLLIPOP libraries.

getting error in i2c wirite. attached the screenshot of logcat and dmesgs

could not able to figure out issue in which layer,

HAL, libnfc-nci, JNI and Framework.

Hope the linux driver is fine.

help me to resolve the issue

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.
