Installing an ISR without any framework

Recommended Posts


  Hi, trying to install a char driver without any driver framework. The only thing I can not install is getting the Interrupt through to the interrupt servce routine

  err = request_irq(irq, handler,
        "can4linux", &can_minors[minor]);

irq is the Interrupt number of the CAN controller, it is fixed in the A20 to 58.

I do get no error messages, but the isr is not called. What I am missing?

By the way, it worked  an Bananian 3.x
