Hello,
Thank you for the input, but no, the power supply is out of the enclosure.
We just lost a 2nd ARM after 3 days of running in the same enclosure.
So that rules out a problem associated with a manufacturing defect (we
think and hope...).
The OS does not seem to crash, but the network functions and the RS232
interface simply stop working after heat build up.
If we remove the lid of the enclosure, everything starts working again
correctly, without a reboot!
By the way, we purchase extended temperature ARM boards. Is there a
way to identify a ARM with the extended temperature option from one
without the option?
Thank you in advance for any input.
