Hello
I have now look deeper into my sources and I had make many debugs with the console. I have found that at the emulator the register CM_WKUP_CLKSTCTRL is set to 0x3E16 and at my app the register is set to 0x1F16.
That means the CLKACTIVIT_TIMER1_GCLK is not set at the app.
I don't know why? How could I enable this Clock?
regards Tobias
