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,
// IRQF_TRIGGER_RISING,
IRQF_TRIGGER_HIGH,
"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?
Greetings Heinz
By the way, it worked an Bananian 3.x
