Description

Ning is adding a watchdog feature for the PXIE loss task. When an integration window interrupt occurs (when a new average value is available), the firmware starts a timer. If the CPU hasn't acknowledged the interrupt in a short time (tens of microseconds?), the hardware will trip.

When the new firmware is installed, Rich will add the extra hardware access and it can be tested.

History

#1 Updated by Richard Neswold almost 2 years ago

  • Priority changed from Normal to High

I should have bumped the priority when I created this issue. This feature protects the machine from software hangs or reboots so it has high priority.

#2 Updated by Richard Neswold over 1 year ago

Support is in the driver (vme-blm|cc5047af) but still needs to be tested.

Ning has provided the firmware.
