kernel debugging laptop with no serial or firewire

WINDBG
1

Hello all,

I have laptop with no serial or firewire. I heard that debugging via
USB is kind of buggy so I was thinking about getting a usb to firewire
converter for the laptop and giving that a shot. Has anyone ever done
this before? Does it work okay? Are there better ways to kernel
debug a laptop without firewire or serial?

Thanks
J

I always have a Firewire PCMCIA/PC card handy for just such a purpose. It’s typically always worked fine. I have NOT tried a Firewire to USB adapter, however, so I can’t say how that will work. If you’ve got a PC card slot, though, the aforementioned Fireware card should do the trick. I do have a USB debugging cable but have never been able to successfully get it to work. Firewire is hands down my favorite way to go.

If you have an expresscard or pc card slot, I would use a 1394 adapter.

Otherwise you must use usb debugging. USB-to-x adapters won’t work if the debuggee-end is USB.

All of of the Firewire-to-USB converters I’ve seen are actually
Firewire-disk-to-USB-disk converters. They do not work for arbitrary
devices. Remember that the kernel debug device support is extremely
low-level, built in to the debugger in the kernel. It does not use the
normal device stack, and so does not have the usual this-to-that
flexibility.

Are there better ways to kernel debug a laptop without firewire or serial?

It’s an ugly situation. You can try a PCMCIA 1394 adapter.

Any chance your system has a PCMCIA or an Express slot available?

I’ve not tried the 1394 over USB… it should work, but I’ve not found a card solution that hasn’t worked.

1394 over USB will absolutely NOT work in target machines.

You MUST have an OHCI 1394 controller accessible directly off one of the PCI buses in the target box.

Otherwise 1394 debugging won’t work.

An easier way would be to connect your laptop to the docking station which
may give you access to a COM port.
