Are you shure logical IRQ25 is connected to your PC104plus slot? Have a look into CPU registers UIC0_PR and UIC0_TR: Is IRQ25 configured for negative level triggering (like the PCI bus need)? Register CPC0_CR0: Is the physical IRQ0 (logical IRQ25) enabled? Hope it helps -- JB ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
