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?
