Forum Topic - Wrong IRQ return by the pci utility or the pci_read_config8 function.: (1 Item)
   
Wrong IRQ return by the pci utility or the pci_read_config8 function.  
Hello,

    I write and interrupt handler for a PCI acquisition board. To obtain the interrupt number of the PCI card i use the 
pci_read_config8 and validate the result with the pci utility.

    When i use the InterruptAttach function to associate the IRQ to my ISR, nothing append. After many test, i discover 
that i must use another interrupt number. In my test, the IRQ obtain by the pci_read_config8 is 0x03 and the IRQ i must 
used with the InterruptAttach is 0x17.

    Any idea of what append?

Thank you, Sylvain
