watchdog timer and DAQ conflict
Hello, everybody!
I have a problem and would be grateful to anybody who would help me to solve it.
I have Advantech PCI-1713 DAQ board, which uses interrupts for delivering voltage conversion results.
My motherboards are Advantech PCA-6178C and PCA-6010.
I am testing system reset using on-board watchdog timers.
It seems that interrupts continue happening from DAQ board after watchdog's reset, resukting
some interrupt conflict.
There is an issue:
While using PCA-6010 and triggering reset (via watchdog) with PCI-1713 diriver active system hangs before getting into
the bootloader.
It's still rebootable with ctrl-alt-del, but it all goes the same.
After ON/OFF system (naturally) boots.
