I am newbie on Atxmega128A3U. Problem i am facing is I have programmed two of my custom board based on Atxmega128A3U.
I am transmitting data using USART at baud rate 38400.
Data frame transmitted correctly. while after passing some time, means in winter with temperature change data is being corrupted.
What i did is change value of baud rate and again its work fine.
Another test conducted today is I turned On the device and put it into freezer at -4 degree centigrade. Suddenly it starts sending too much garbage data.I am shocked. Its data sheet is saying that it can work in -40 degree--- +80 degree centigrade.
I am using internal 32MHz oscillator with no division.
Please update with your valuable suggestions.
