PIC18F452 Lockup during reboot
PostPosted: Fri May 23, 2008 12:44 am     Reply with quote
PIC 18f452 works great in Lab. After connecting control unit to real system, PIC will be lockup after 12 hours. Voltage is OK. Nothing is running. Because noise on power line, another embedded board was reboot and OK. But PIC was not able to boot normally.

No way to reproduce this in Lab. PIC is always running and never stop.

Please help.

We have discussed this type of problem many times on here.
It's better if you read all the previous threads. Here are a few
of them. There are probably at least 20 threads on it.
