I’ve been developing an application on M4 core of VF61, based on FreeRTOS supplied by Toradex.
I need to use some of the Timer peripherals of the VF61:

  • Flex Timer Module (FTM)
  • Periodic Interrupt Timer (PIT)
  • Low-Power Timer (LPTMR)

Are some of these peripherals used by the Win CE6 image supplied by Toradex (A5 core)?
Are some of these peripherals used by the FreeRTOS image supplied by Toradex (M4 core)?
Or can I use all of them on my application on M4 core?

Thanks in advance

Hi Vix,

I use PIT1 in some operations. Everything else is free to use.

Only to be 100% sure between 0-based or 1-based notation: do you mean channel 1 of PIT peripheral?
And so chanell 0 and channels from 2 to 7 are free to use?

Yes. And even that I only use on boot and on suspend/resume cycle.
