How can I know chip version and rf configuration?

[jiafangguo]

Hi

We use PN7120A0EV/C10801Y, XTAL : XRCGB27M120F3G00R0. According to AN11690, we port android version software to our qcom 410 board.

I can enable NFC and android beam. But can not transfer any data or detect any TAG. I suspect PN7120 doesn't detect devices. RF configuration maybe has a problem. I got all configuration file from AN11690. And have no idea how to configure NXP_RF_CONF_BLK_x? 

Can you guys help me? The attachments are my configuration files.

Thanks,
