Hi Ruiyu,
Windbg would complain
"Cannot start kernel debugging using
exdi:clsid={66C102B6-D4F6-4F8E-84CC-B09802D364EA} Paremeters, HRESULT
0x80010105 The Server threw an exception."
and refuses to start.
Please refer to the 2 years old thread
http://feishare.com/efimail/messages/20110730-0433-Re__edk2__UDK_debugger__and_windbug_problem_on_DuetPkgX64_-_Kinney__Michael_D_.html
I tried Mike's suggestion of clearing the workspace but it doesn't seem to
help. Please contact me if you need more information.
Thanks,
Calvin

Calvin,
What issue did you meet using WinDbg for UEFI over serial?
Thanks,
Ray

I develop option rom as well as uefi drivers. I use American Arium XDP3
debugger. It's expensive but well worth the money. It has all things you want.
Their support is very good. The bonus is that they are local to us in SoCal so
we can stop by their office easily.
The only problem is finding systems with xdp port.
I tried WinDbg for UEFI over serial but no luck so far.

Typically the low level things: firmware, drivers. I mostly use emulators
(qemu, vmware) but sometimes things that work there do not work on physical
systems.
I'm looking for utility/hardware that would let me to debug problematic
machines (even without source code) from the very beginning of firmware
execution. Wanted features at this point are pretty standard: breakpoints,
registers introspections, memory dumping functions etc. Can you recommend
something for this particular case? Thanks.

I could you give you better guidance if I knew what type of UEFI code you were
trying to debug (UEFI driver? OS loader? UEFI app? Firmware/BIOS?).
The EDK II DEBUG() macro is surprisingly useful as a starting point. It's
output-only debugging, but very useful for seeing output from stages of code
where you have no display output.
Thanks ... br

Dear list,
What do you use for debugging your code on real world systems? Is special
hardware really necessary, I'm curious what professionals use in this field and
what is the most recommended product.
So far I have found following options:
- http://www.windriver.com/products/simics/ (software)-- but I have no idea
how much does it cost or if it will be enough for debugging the firmware
(product promo: http://www.youtube.com/watch?v=lYAukMyek9A )
- DQ57TM (hardware)
Thanks,
Eric
