Execution time different

[stephane.arquer at c-s.cnes.fr (Arquer Stephane)]

Hello,

I use a leon2  cpu and I have two way to load the code.
The first one is grmon and the other is Redboot with a binary file
generated by sparc-rtems4.7-objcopy -O binary file.elf file.bin.
I don't have the same behaviour with the same code.
With grmon, a calcul function last 120ms
With redboot, this function last 340ms

I check MCFG2 :
Grmon: 	  03801460
Redboot: B0801460

And I modified it in grmon but the time is always 120ms.

Does anyone know what is initialise by grmon which is not done by
Redboot ?

Thanks for help.
