Hi all,Apologies for such a basic question. I am trying to write an ISR on a MPC551x. When I tried to use the interrupt attribute with powerpc-eabi-gcc such as _attribute_((interrupt_handler)) foobarISR(void) { }
Assuming you're talking about an interrupt handler in Linux, you don't need to do anything like that. The actual interrupt entry is assembly code. Search existing drivers for "irqreturn_t" to find examples of what an interrupt handler looks like, and "request_irq" for how to hook the handler into the interrupt.
