Hello everybody,

I am using the external clock option in a evaluation board for the SPC56EL70L5. Thus, I selected ''Oscillator bypass'' in configuration.xml. Even the example projects don't work with that option, while if I left it unselected the examples work only if i put the external clock (this makes me think that because of my jumper configuration I am already working with the external clock).  

The stack with oscillator bypass is attached.

Thank you very much.

Hello Stefano ,

Did you try to unplug Y1 ?

cf Chapter 3.4

Y1 is a 40MHz thru-hole crystal. The crystal is plugged in a dedicated socket and it can be replaced without using a soldering station.

   Best Regards
