iMX6 - GPT - linux kernel 3.0.35

davide_beretta — Fri, 17 Jan 2014 14:19:39 GMT

Hi everybody,

in my application I want to use the General Purpose Timer (GPT) of i.MX6Q but it is already configured and used for a delay routine in the kernel 3.0.35.

Is there a way to avoid the kernel to use GPT ?

thank you

Hi, Davide

GPT is used for system clock source for kernel, so you can NOT touch it, all system time and broadcast timer are from GPT. You can try using EPIT, there are EPITs not used currently. Can I know what do you want to use GPT, to be a timer or counter?

I would like to use it as a counter.

Thank you.

Hello Davide,

how did you manage to use the GPT?

Have you configured a second timer?
