DSP 56f8367 clock problem ?!

Hi all,

I have this problem:

I program my DSP with USB TAP (ldm Internal memory: pROM-to-xRAM) and all work properly, but when I reset the DSP by a Power off something happen.

When I power on the DSP it works but it seem works with a different time extension like if the clock period is altered.

To explain better:

I introduce a delay, of 1 second, in a simple cycle.

It works with this delay time till I switch off the power.

When I switch on the power the time delay, that was of 1 second before, now take about 15 seconds... how could it be?

I'm not using the procesor expert, but simple C code wrote all by myself.

I think it's not a hardware problem because I create a similar procedure with processor expert and it works properly also after a power on reset.

If someone know any possible reason / solution ...

I solved the problem.

There was a multyple memory configuration in the file 56F83x_init.asm

pROM-to-xRAM utility and also xRom-to-xRam
