We have made a product by using Atmega328pb.
Almost all GPIO
Software Atmel Studio 7
Suppose we have produced 10000 devices. and all devices is ON 24*7.
But the problem is out of 10000 devices few devices like 5-10 devices is getting hanged(no response or random behavior) randomly and when I am restarting the device it starts working normally or very few gets permanent damage.
What would be the root cause like code issue, hardware issue, power supply issue?
And How can I resolve this issue.
Please help me out.
Thanks in Advance.
