TMS570LC4357: Finding the startup time

Part Number: TMS570LC4357
Other Parts Discussed in Thread: HALCOGEN

Tool/software:

Hi, 

I have initialized peripherals in HalcoGen for 16 MHz oscillator frequency and PLL set for 300 MHz. And set the entry point as c_init in linker cmd file and using PMU registers, captured the execution cycles from the reset(entry point in linker) to main() entry. I am getting approx 500 microseconds as startup time. Is this timing justified? Am I missing something?

My goal was to check the startup time for the processor with basic initializations done.

Thanks,

Nishitha
