This is from "BaseTools/Source/C/GenFv/GenFvInternalLib.c":
case EFI_FV_FILETYPE_DRIVER:
case EFI_FV_FILETYPE_DXE_CORE:
//
// Check if section-alignment and file-alignment match or not
//
if ((ImgHdr->Pe32.OptionalHeader.SectionAlignment !=
ImgHdr->Pe32.OptionalHeader.FileAlignment)) {
//
// Xip module has the same section alignment and file alignment.
//
Error (NULL, 0, 3000, "Invalid", "Section-Alignment and
File-Alignment do not match : %s.", FileName);
return EFI_ABORTED;
}
NewPe32BaseAddress = XipBase + (UINTN) CurrentPe32Section.Pe32Section +
CurSecHdrSize - (UINTN)FfsFile;
break;
This could be a problem with the gnu-efi build system; it probably doesn't
ensure the equality of the two PE32 fields in question.
For example I just built the "apps" directory of gnu-efi:
$ objdump --private-headers apps/t6.efi
[...]
SectionAlignment 0000000000001000
FileAlignment 0000000000000200
[...]
Cf.
$ objdump --private-headers Build/OvmfX64/DEBUG_GCC48/X64/QemuVideoDxe.efi
[...]
SectionAlignment 0000000000000020
FileAlignment 0000000000000020
[...]
It could be easier to build your program inside edk2.
