pn548 (npc300) porting Android 7.0 problem

[imx5x]

Hello NXP Community,

These days, I am porting PN548 in Intel Android 7.0 BSP. There is a cannot read tag problem.

Problem:

After NPC300 is powered on and init, NPC300 can read and show tag information. 

However, if the NPC300 is nothing to do about 10 sec, NPC300 cannot read tag.

I need to go to Android Setting to turn off NFC and then turn on NFC to restart NPC300 and it will restart not read tag problem. 

when this problem is occurred, there is an error in debug log as below:

I guess NPC300 is in Standby mode suddenly without notice Android 7.0 HAL and Service causes Time out error.

I also add NXP_CORE_STANDBY={2F, 00, 01, 00} to libncf-nxp.conf file to Disable Core Standby, but the problem is not fixed .

How Can I disable NPC300 Module Standby or idle mode?

My environment:

OS: Intel Android 7.0 64bit
