Martin PelletierI used the uart (DIN,DOUT) on the mDot at 38400baud in order to communicate with another processor.
When i put my interface board on the frozen around -20°C, the mDot generates a checksum error on my uart port!! But as soon as i remove it on the frozen, after 20 minutes it begins to work well!! Then i suspect the crystal drifting the frequency operation which affects the baudrate!!
Do you have any idea about it??
Thx!
Martin PelletierI found my problem 
The mdot was not concerned!!!
The mdot works good under -20°C
