Yes I read that document debugging-via-ohci1394.txt, I played with attempts to debug kernel over firewire several days, no success. The document describes fireproxy utility, but when I found sources on
http://halobates.de/fireproxy and tried to build, it was not functional, it seems to be not updated for newer kernels. My case is special - I cannot use kernel debugging over ethernet because debug target binary is netfilter module and I must debug network communication through network cards. Target machine is notebook without serial port so I buyed PCMCIA serial port and after some time spent on it I am able to debug it through serial port, but still I am wondering if there is not way how to debug kernel over firewire ? Does really nobody uses this way ? All information from forums I found was relating to fireproxy, does anybody knowns some other utility used for debugging over firewire ?
