Capture the packets if someone ack your arp request, if you can capture someone's ack then Change another MAC address on your board may solve the problem.

My problem is no interrupt is triggered when some packets arriving. The network chip is Micrel KSZ8842-16MQL. There is no driver for uclinux, so I port the linux driver to uclinux. I changed the interrupt to IRQ_PF12 when request_irq is called in device open function. Also I add the following code to generic_board.c because the chip manual said the interrupt source are level trigger active low. static struct resource ks8842_resources[] = { { .start = 0x20200300, .end = 0x20200300 + 16, .flags = IORESOURCE_MEM, }, { /* * denotes the flag pin and is used directly if * CONFIG_IRQCHIP_DEMUX_GPIO is defined. */ .start = IRQ_PF12, .end = IRQ_PF12, .flags = IORESOURCE_IRQ | IORESOURCE_IRQ_LOWLEVEL, } }; And some printk code in interrpt function. The result is the device could be probed(kernel start) and opened(ifconfig) correctly. When I ping some hosts, arp request is sent. But when arp response back, it seemed nothing happened. The eth0 status of running ifconfig shows nothing received and /proc/interrupts shows no IRQ_PF12(45) interrupt triggered. Is someone have experience in porting this chip to uclinux? Thanks in advance. _______________________________________________ uClinux-dev mailing list [email protected] http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by [email protected] To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev _______________________________________________ uClinux-dev mailing list [email protected] http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by [email protected] To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
