I have been sitting for some time to try to figure out a way to
completely skip the PLL AND at the same time use the main oscillator
bypass feature. I can see that the usage of the PLL is more or less
directly coded in to a macro in the header:
hal/arm/at91/at91sam7s/current/include/hal_platform_setup.h
But if i want to completely bypass that feature and follow the
instructions in the datasheet that states OSCBYPASS should be set to 1
and MOSCEN must be set 0 - i have absolutely no idea on how to put
that functionality in to the system without hacking a lot of code that
i in principle have no knowledge about...
Do anyone know how to make that bypass?
