Hii Team ,

I go through with the below link document :

https://www.nxp.com/docs/en/application-note/AN11697.pdf 

 

But I am facing an issue with it , that pn5xx driver is compiled .ko and .o files are created but after implement the image in imx8mm board , there is no any message I am getting in the boot-up process .

 

Below are my changes in kernel :

Hi Pramod

 

there may be confusion as AN11697 is written for PN71xx family, for example

below PN5xx datasheet does not mention i2c interface but spi:

https://www.nxp.com/docs/en/data-sheet/PN5180A0XX-C1-C2.pdf 

May be relevant to consider below PN5xx patches an adapt them for i.MX8MM.

NfcRdLib for i.mx7dsabresd 

 

Best regards
igor
