Part Number: PROCESSOR-SDK-AM62X
Tool/software:
Hii,
I am working on the AM62x processor and I am trying to toggle the GPIO pins. However, after making changes in the k3-am62x-sk-common.dtsi file, I am unable to achieve this. Could you please guide me on how I can toggle the GPIO pins successfully please find the code and output i have attached below can you please suggest how to resolvre the issues...
