Meaning of message: CID: ISR still active !

      Meaning of message: CID: ISR still active !

      Hello,

      I received today a board from a customer where the CAN bus doesn't work any more.
      While looking at the debug output I get always the message: "CID: ISR still active !"
      What does this mean exactly? What is ISR?
      Hope there is no hardware defect?


      Thanks a lot, Kaiser

      Hello,
      ISR means Interrupt Service Routine. It looks like you get an interrupt (receive?) all the time.

      Hello,

      seems to be a hardware defect. I changed the NetDCU board and with the new one everything works fine.
      In serial debug there is following output:

      Source Code

      1. MBD: ActiveKey (copy) = Drivers\Active\18 (@ 0x00041010)
      2. PIF: ActiveKey (copy) = Drivers\Active\19 (@ 0x00041200)
      3. Version: 12
      4. CID: ActiveKey (copy) = Drivers\Active\20 (@ 0x00041380)
      5. CID: Wait for Reg 31 failed !!!

      21. Transmit IRQ
      22. Transmit IRQ
      23. Transmit IRQ
      24. Transmit IRQ
      25. usw.


      Shoud I send it back to repair?


      Best regards, Kaiser

      Did you already try to set registry to default?
      If this not help send it to us (via your distributor) by request an RMA.
