[MinnowBoard] [edk2] Bug in DebugCommunicationLibUsb

[Tian, Feng]

Could you add the below debug message to the beginning of InitializeUsbDebugHardware() for further debugging?

DEBUG (( EFI_D_INFO,  "UsbDbg: Handle = %08x, Base = %08x, Offset  = %08x\n", Handle, Handle->UsbDebugPortMemoryBase, Handle->DebugPortOffset ));

Please stick to 0.78 version and set pcds to the first configuration you shared.

As you can connect usb debug device with WinDbg, we suspect some data structures may be corrupted after memory migration in MemoryInit.

Thanks
Feng

Hi,

I follow UDK Debugger user manual version 1.91 and my PCDs settings are matching with real because values for PCDs I see in procesor datasheet. Also, with success it connected to the UDK debugger tool+WinDbg andafter that firmware stoped and after in WinDbg I command go and than it stoped in MemoryInit. And I s
I try default PCD settings

 ( gEfiSourceLevelDebugPkgTokenSpaceGuid.PcdUsbEhciPciAddress |0x000E8000|UINT32|0x00000003 ( ehci -> 0.29.0 )
gEfiSourceLevelDebugPkgTokenSpaceGuid.PcdUsbEhciMemorySpaceBase |0xd0000000|UINT32|0x00000002
gEfiSourceLevelDebugPkgTokenSpaceGuid.PcdUsbDebugPortMemorySpaceBase |0xd0000000|UINT32|0x00000001 )

 and WinDbg was connected and try debug but firmware stoped in MemoryInit.

When I try  PCDs settings

gEfiSourceLevelDebugPkgTokenSpaceGuid.PcdUsbEhciPciAddress |0x000E8000|UINT32|0x00000003   ( ehci -> 0.29.0 )
gEfiSourceLevelDebugPkgTokenSpaceGuid.PcdUsbEhciMemorySpaceBase |0x00000000|UINT32|0x00000002
gEfiSourceLevelDebugPkgTokenSpaceGuid.PcdUsbDebugPortMemorySpaceBase |0x00000000|UINT32|0x00000001

nothing was changed, and WinDbg was also connected on MinnowMax version 0.78 . But on MinnowMax version 0.76 firmware was connect to the WinDbg and  stoped me in SEC phase and I got only this log  >>>>SecStartup .
Log for MinnowMax version 0.78  :

>>>>SecStartup

Problem :  May I got souce code of MemorInt.efi because firmware stoped in MemoryInit  I want to know what's  happening ? I try opened and got code in IDA but it wasn't readable.
               May somebody tell me  for PcdUsbEhciMemorySpaceBase and PcdUsbDebugPortMemorySpaceBase PCDs which value is correct ?

Best regards ,
