site_archiver@lists.apple.com Delivered-To: darwin-kernel@lists.apple.com Importance: Normal User-agent: SquirrelMail/1.4.9a-3.berkeley thanks for the quick response ! in trying to further debug the problem, I also noticed that the AppleFireWireKDP.kext wasn't loading properly on the target machine. the error message is as follows: 16AppleFireWireKDP is not compatible with its superclass, 9IOService superclass changed? so it seems like I may need a new AppleFireWireKDP.kext as well thanks -rimas

Uunfortunately, the FireWireKDPProxy included with the last FireWire SDK25 had an issue during compile time and thus does not work with Tiger. This will be fixed in an update to the SDK.

In the meantime, if anyone needs a copy of the FireWireKDPProxy, please let me know.

Rimas, I'll send you a new proxy now.

Greetings,

I'm trying to do two machine debugging via Firewire, using two MacBook Pros (one is the most recent rev, one the previous rev, both running 10.4.10).

I've obtained the latest FireWireSDK (25) and installed the AppleFireWireKDP kext on the target machine.

When I try to run the FireWireKDPProxy program on the debugging machine, i get a "bus error" and generate a crashlog that looks like this:
