Honestly I don't think the board wiring is incorrect. FPGA goes to IRQ0 and miniPCI is wired to IRQ1. Maybe there's a crosstalk problem since the pull-up resistors are=20 packaged inside an array ... I'll check this. regards, Andr=C3=A9 Scott Wood schrieb: > Andr=C3=A9 Schwarz wrote: >> There are two external PCI devices connected (FPGA + miniPCI socket). >> The FPGA is working fine and uses IRQ0 for its PCI_INTA line. >> >> As soon there's a miniPCI module present and the driver loaded=20 >> (actually an ath5k WiFi module) the system complains after a while : >> >> irq 48: nobody cared >> handlers: .... location of the FPGA irq handler >> Disabling IRQ #48 >> >> -> This is weird since the FPGA isn't working at all and IRQ0 is *not*= =20 >> asserted ! >=20 > Are you *sure* that IRQ0 isn't asserted?
