Hi, I have a interrupt driven task. The interrupt is generated from a external board each 500usec. I have a counter that is counting at 0.5 usec, if the counter is not reseted before 540 usec it will generate a alarm (hardware watchdog). The problem is: - The watchdog alarm aprox. each 1 second. This means that the counter is not reseted, hence the task loose syncronization. What could be the problem? - I Observed that the CPU load rise at 8% every 1 second. I have installed RTLINUX2.2a Enzo -- [rtl] --- To unsubscribe: echo "unsubscribe rtl" | mail [EMAIL PROTECTED] OR echo "unsubscribe rtl <Your_email>" | mail [EMAIL PROTECTED] --- For more information on Real-Time Linux see: http://www.rtlinux.org/rtlinux/
