What is the use case of user keys (FUNC1 & FUNC2) on IMX7d?

[vm18553]

Hi,

There are two user keys available on IMX7d i.e FUNC1 and FUNC2. What is the use of these two user keys?

Suppose if these two keys are already used by kernel driver then Can I use it for other propose? I want to use any of the key to generate GPIO Interrupt.

Regards,

Vishnu

Hi Vishnu,

In the next link I shared a code for GPIO interrupt in a kernel moduleIssue with configuring GPIO as an interrupt - i.MX6Q 

If there are any other references in the device tree to the pin that you are using you must delete o comment out them.

I hope this helps.

Regards,
Carlos
