Hi Edwin,
Thanks for
helping out. The `lspci –s 1:0.0 –vvv’ generates below output:

Debugging DM
using gdb indicates the program stops at
hw/pci/passthrough.c:560. Any idea what could be the cause? I
don’t know how to capture the whole screen output from the
UOS kernel, the detailed gdb log is attached for your
inspection. Thanks.

Tonny,
The config is ok.
Could you pls. try gdb to catch the seg fault? Just replace
the 'acrn-dm' with 'gdb --args acrn-dm...' in your launch
script.
Did you paste all your console output when launch UOS? And
'lspci -s 1:0.0 -vvv' in SOS should give some helpful info.
thanks,
Edwin

Could you pls. paste the detailed error mesg.
We do have some passthrough rules user need follow, e.g.

Hi there,
I got an Aaeon’s
AI Core, which integrates the Movidius Myriad2 chip
and a USB3 controller on a PCIe card, and I’d like to
drive it from the UOS on the UP2 board. I follow the
Getting Started Guide and I
am able to pass through the built-in USB controller (PCI
00:15.0) to the UOS. Since my Movidius PCIe card is
presented to the system as a PCI 01:00.0 device, I tried
to use the similar way to pass through it to the UOS, but
the DM aborts and can’t launch the UOS.
Is there any restrictions to pass
through PCI devices to UOS? I’ve tried to unbind the
device thru the pci-stub, and add “-s
21,passthru,1/0/0” option to the DM, but the DM can’t
launch the UOS with these modifications. What’s the
proper procedures to pass through an *external*
USB controller? Any pointers would be appreciated.
Regards,
Tonny
