Hi I am experimenting with debugging linux kernel using firewire and having problem making it work. I pretty much followed " Documentation/debugging-via-ohci1394.txt". On debugged (target) machine: kernel version - 2.6.30 (with param ohci1394_dma=early) output from: dmesg | grep ohci1394 [ 6.294137] ohci1394: fw-host0: OHCI-1394 1.1 (PCI): IRQ=[18] MMIO=[dfdfc800-dfdfcfff] Max Packet=[2048] IR/IT contexts=[4/4] output from: dmesg | grep ieee1394 [ 7.561325] ieee1394: Host added: ID:BUS[0-00:1023] GUID[474fc00001ecb501] On debugging host: kernel version - 2.6.30 output from: dmesg | grep ohci1394 ohci1394: fw-host0: OHCI-1394 1.1 (PCI): IRQ=[16] MMIO=[d6000000-d60007ff] Max Packet=[512] IR/IT contexts=[4/4] output from: dmesg | grep ieee1394 ieee1394: Host added: ID:BUS[0-00:1023] GUID[00241b00bd3d6d01] Every time I run firescope (version 0.2.2), it only detects the local node. #sudo ./firescope Port 0 (ohci1394) opened, 1 nodes detected Apart from the possibility of a bad firewire cable, is there anything I am missing? -- Thanks, -John |
