How to Interface the NXP PN7160 NFC Module With the i.MX8M Plus EVK?

[Niranjan123]

Hi,

I am working with an i.MX8M Plus EVK and planning to integrate the NXP PN7160 NFC controller (using the PN7160 Raspberry Pi HAT: OM29110RPI-B).

regards,
Niranjan

HI, @Niranjan123 

If you are using Android, please refer to below link  ,  it is about porting PN7160 with i.MX8M nano,

Hi,

Thank you for the link, but I am not using Android.

My setup is:

• Board: i.MX8M Plus EVK

• OS: Linux (Yocto-based Linux BSP from NXP, not Android)

• NFC Module: PN7160 Raspberry Pi HAT (OM29110RPI-B)

• Connection: I2C interface from the EVK expansion header to PN7160 HAT pins

My goal is to bring up the PN7160 in a Linux environment, using the NXP PN7160 Linux driver.

Could you please clarify the following for Linux (Yocto) on i.MX8MP EVK:

1. Does NXP provide a Linux driver (kernel or user-space) for PN7160 that can be used on i.MX applications processors?

2. If yes, where can I find the recommended

   • device-tree binding

   • required GPIOs (VEN / IRQ)

   • Linux kernel config options

   • sample DTS node for PN7160?

3. Which I2C bus on the i.MX8MP EVK expansion connector is recommended for connecting external modules like PN7160?
   (There is no Raspberry Pi 40-pin header on this board, so I want to confirm the correct I2C bus.)

4. Are there any known reference implementations of PN7160 running on an i.MX8M Plus EVK (under Linux)?

Current status on my side:

• Verified I2C buses available: /dev/i2c-0, /dev/i2c-1, /dev/i2c-2, /dev/i2c-6

• Expansion header signals checked in schematic

• Planning to use I2C2 or I2C1 depending on recommended wiring

• Before wiring PN7160 HAT, I want NXP confirmation on:
  ✔ Correct I2C bus
  ✔ Required voltage levels
  ✔ Required IRQ and VEN GPIO pins

Any guidance for Linux + PN7160 + i.MX8MP would be very helpful.

Thanks!
