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 :
