Thanks Olivier! The '.dll' dump looks similar to ^ and contains proper PCD values
at the right address. The '.lib' however shows all the PCDs to be at 00000000:

Disassembly of section .rodata._gPcd_FixedAtBuild_PcdFvBaseAddress:

00000000 <_gPcd_FixedAtBuild_PcdFvBaseAddress>:
   0:    80008000     andhi    r8, r0, r0

Is it all right that these two addresses are different? If so, what else sould I check

to trace the fault?

Thanks,
