Other Parts Discussed in Thread: DM8107

Hi,

What are the MPU timer and 32KHz timer and their difference?

We found that if we use the default MPU timer and run M3, there’ll be high probability a big time gap (1.6sec) between 2 omap2_gp_timer_interrupt occurred.

But if we changed the kernel config to use 32KHz timer, this gap won’t be occurred.We don't know why?

They can be configured in kernel config:

System Type->TI OMAP Common Features->System Timer->Use MPU timer

System Type->TI OMAP Common Features->System Timer->Use 32KHz timer

Our platform is DM8107, with RDK 4.0.0.3

Best regards,
