[edk2] PCD error in new BaseTools

[Evan Lloyd]

I have just tried updating our builds to use the latest BaseTools. (We were using a really old version)
I now get errors from .dsc files that used to work.
The lines in question look like:
gArmPlatformTokenSpaceGuid.PcdRamdiskSize|0x20000000
gArmPlatformTokenSpaceGuid.PcdRamdiskBase|(gArmPlatformTokenSpaceGuid.PcdArmLcdDdrFrameBase - gArmPlatformTokenSpaceGuid.PcdRamdiskSize)

The error for the second line asserts that "PCD (gArmPlatformTokenSpaceGuid.PcdRamdiskSize) is not defined in DSC file" despite the obvious definition in the immediately previous line.

My questions are:
1. Was this an intentional break in functionality, or an accident?
2. Is someone familiar with the Python code able to point me at the likely area of change that caused this, please?
3. Has anyone else seen this problem?

Regards,
Evan

Evan:
I create this usage with the latest BaseTools. It can work. Build tool version: build.exe Version 0.60 Build 18320.

Could you let us know which version BaseTools is used? And, where to get your DSC file? I don't find such usage in EDKII ArmPkg and ArmPlatformPkg.

Thanks
Liming
