I did some profiling of assembly code on OMAP3630 board (ZOOM3). In worst case it takes around 3.28ms and best case around 2.93ms for mpu off mode.
Can you give a bit more details? Which measurement has been taken (ASM only, sleep, wake-up ...?) and what are the significant figures?
For MPU INACTIVE/RET, it is less than 30us.
Mmh that is the resolution of the 32kHz timer, so I guess you get either 0 or 1 timer cycle depending when you start the measurement. IMO the 32kHz timer is too slow to measure those fast events.
However as Kevin mentioned in other email, it would be better to find out a way to trace inside assembly code as well.
OK that could be done but first I would like to make sure such a complication is needed.
