Disable the External oscillator 32768 Hz on SAMA5D34-EK

Tue Jan 24, 2017 5:10 pm

Hi,
If I disable the external oscillator (32768 Hz) and I use only the 32 kHz internal oscillator, I might have problems with the following devices?
-Display LCD
-USB
-Ethernet
-RS485
-GPIO
-DBGU

Thank you

Because Sometimes when I restart the board the external oscillator don't start, and it causes the SoC blocked in Reset. I have to remove the RTC battery and wait the VDDBU go down.
