When PCD type is VOID*, MaxSize must be specified to say how much value need to be updated. This tool checks whether the input PCD information is valid for the input binary image, but doesn\rquote t check the format of the binary image. \f1\par 10\f0 PatchPcdValue tool usually works together with GenPatchPcdTable tool to set the specific value of a patchable PCD into the binary EFI image. \f1\par 11\pard\keep\keepn\nowidctlpar\s2\li-1440\sb400\sa60\sl-340\slmult0\cf1\b\f0\fs28 Options\par 12\pard\nowidctlpar\sb200\cf2\fs18 -f PCDOFFSET, --offset=PCDOFFSET\f1\par 13\pard\nowidctlpar\li360\sb200\b0\f0 Start offset to the image is used to store PCD value.\f1\par 14\pard\nowidctlpar\sb200\b\f0 -u PCDVALUE, --value=PCDVALUE\f1\par 15\pard\nowidctlpar\li360\sb200\b0\f0 PCD value will be updated into the image.
