AM6442: Peripherals > Timer Modules > Timers

Hello,

Thanks for the follow-up question. Looks like my discussion with the devs got sidetracked and the question of "is there Linux support for using these timers" never got answered. Restarting that discussion. Please ping the thread if I have not replied by the end of this week.

Regards,

Nick

Hello Xixiguo,

Update, I have not heard back yet. Reaching out to the developers again to see if we can get some more information for you. Please ping me again if I have not responded within a few days.

Hello Xixiguo,

At this point in time, there is not Linux support for the AM64x timer modules. i.e., no support for timers as a generic HW timer, no support for timer as a PWM output. I am following up with the development team to see if there are plans to add this in the future, and if so what that timeline is. Please ping the thread if I have not replied by the end of the week.

Nick

Hi Nick，

Got it, thanks for your updates again!

Hello Xixiguo,

Actually, can you help me out here? What will your design use timers for?

One of the reasons this feature was put so far back in the schedule is that we don't have much documentation on general purpose timer usage. Context around why a timer would be used in a Linux design could help our developers prioritize features when they begin development.

Thanks,

Nick

Hi Nick

Any update?

Hello Ethan,

My last update is here: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1107119/am6442-peripherals-timer-modules-timers/4114692#4114692

If you have any feedback for general purpose timer use cases that I should record, please let me know.

Regards,

Nick

Adding a clarification for future readers:

Linux support for using the dedicated hardware timers is not yet added. However, the Linux kernel DOES provide support for timing events using the Linux system time. Take a look at the kernel APIs around add_timer() / mod_timer() / del_timer().
