[ECOS] ROMRAM application runs much slower than RAM

[Harshit Suri <h dot r dot suri at gmail dot com>]

Hi
I've built an application code both in ROMRAM startup and RAM startup mode.
The code blinks LEDs.

The ROMRAM application runs *significantly* slower than the RAM
version. The time between LEDs blinks is much longer in ROMRAM. I've
generated the delays using 'for' loops like so:

while(1)
{
     LEDs ON;
     for (delay = 0 ; delay <100000;delay++);
     LEDs OFF;
     for (delay = 0 ; delay <100000;delay++);
}

All parameters like clock frequency and RTC settings are same in both.

This puzzles me. Both startup modes finally run from RAM.

Then why this disparity in speeds?
thanks
