How to use PN532 module to iMX8M Plus EVK via UART3?

[NealZhang]

Hi all,

I am trying to testing a PN532 module. This module support to connect to core board with I2C, SPI, HSU. I connect this module with UART3 on iMX8M Plus EVK board(EXP_CN PIN 8/10). But I cannot get any info with stty or minicom. BTW, I get nothing when i shot pin-8 and pin-10

I did not update image in the EMMC

Someone could have some advice?

You need align the software for the UART3

[NealZhang]

You mean I need to modify the DTS file, and recompile the image to enable UART3?

[Rita_Wang]

Yes, you are right.

Sry Sir,

I check the dts file of imx8mp-evk, and the uart is set as below

However, I cannot get anything with connecting the pin of UART3_TX and UART3_RX

Is there any other problems?

Thank u very much.

Hi, Rita Wang,

Could you please let me know if the PN7160 can be used with the libnfc-nci library? I read AN11697, which is a guide for using libnfc-nci with PN7120 and PN7150. However, I couldn't find any information indicating that this library supports the PN7160.

In addition, if the kernel driver nxp-pn5xx also supports PN7160 or not?

By the way, I'm going to integrate a NFC module into a linux board based on I.MX 8MPLUS, and we plan to use PN7160 for the advice from NXP official website
