Sai, I think it should be ok if /Od takes effect. Could you double check those modules' Makefile files in build directory? Is the /Od compiler option really added in CC_FLAGS macro?
Ray, Do you have any comment on this issue?

The symbol path looks fine to me as I am able to step through the code. I have set "*_*_*_GENFW_FLAGS = --keepexceptiontable" as well.

And I can see Initial serial dump on the Terminal redirect port. We don't have any standard platform yet, so using the DELL laptop to test USB/ Bluetooth Functionality. And I believe the exception happens after couple of protocol interfaces are loaded, I think we entered into the DXE phase (Not sure though). If it is not a supported scenario, due think it make sense to chase it or try to load it standalone if we have to debug the Dxe Driver.

We didn't enable and test such use case. Do you see the connection of Windbg with target? The exception is not printed by EDKII Duet, it's more like legacy bios.

Yes, the driver you saw is a UEFI driver and only for DXE phase. To enable this feature, you need develop a new DebugCommunicationLibFtdi library instance for SEC/PEI/DXE phase.

Hi Feng, I have the Ftdi driver (optionrompackage) part of the image, unfortunately this will not get loaded during early DXE phase (OR) supports the debug agent lib right? I believe the debug agent works with "debug communication lib usb" (or) "debug communication serial port", if not mistaken.

Hi Tian, The host is fine, how about the Target? The problem is with the Target the Laptops/pc no more serial ports, so using the USB adapter?

For Usb2Serial cable, we support the usage that the cable's usb end is connected with Host and the cable's serial end is connected with Target. By this way, Host will identify a new COM port when connecting this cable like above. UDK Debugger will treat it as a real serial cable to access.

Hi, Need small clarification, to connect to Host running WinDbg/UEFI debugger tool , do we have support for "USB->Serial Adapter" on Target ? What I see "DebugCommunicationLibSerialPort" is hardcoded to 0x3F8 base address? Unfortunately some of the DELL laptops, doesn't have serial port or usb debug ports? So wondering if we have support for USB->Serial adapter attached to "FtdiUsbSerialDriver". Thanks for your quick response. Sai
