TMS320F28379D: CPU timer0 register

Anuj Maheshwari

Is CPU timer register common for both CPUs? Is it possible to start and stop the CPU timer in CPU2 and get the count of the timer by using CPUTimer_getTimerCount in CPU1 without using IPC? In short, is the CPUTimerRegister common to both the CPUs or are their two different registers for individual CPUs?

Each core has three timer modules. They are not shared across the two cores so there isn't a way to read the timer count on CPU1 if it was configured on CPU2. You could look into the IPC module (Inter Processor Communication) to send the counter value from CPU2 to CPU1, but there is no inherent way to do what you are trying to accomplish.
