[MinnowBoard] [edk2] Bug in DebugCommunicationLibUsb

[Anteja Vuk-Maček]

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 ?
