I see in sysinit() the clock configured from the external 50Mhz oscillator. On the schematics I see also crystal 12Mhz connected. What do we need it for? Can we omit the crystal?

Dear Evgeny Erenburg,

From what I saw on the Schematics you can  disconnect the 12Mhz as long as the MCGOUTCLK has a clock source.

in the schematics (5.1.1) at the bottom there is some information about this clocks and some restrictions. please check that sections and tell me if it works.

Have a great day !

Best Regards

Jonathan
