VolInfo.exe - Displays the contents of a firmware volume
VolInfo [-x <XrefFile>] [--offset <Offset>] <InputFile>
VolInfo displays the contents of a firmware volume residing in a file for informational purposes.
If no options are specified, tool prints usage.
-x xref, --xref xrefParse basename to file-guid cross reference file(s).--offset offsetOffset of file to start processing FV at.-h, --helpShow this help message and exit.
The action was completed as requested.
The action failed.
Assume that $(WORKSPACE) is /home/joeuser/src/edk2 and the firmware volumes have been built into Build/EdkUnix/DEBUG_UNIXGCC/FV:
~/src/edk2$ VolInfo Build/EdkUnix/DEBUG_UNIXGCC/FV/FVMAIN.fv
Assuming that a firmware device image had been built and that the firmware volume of interest resided at byte offset 65536 of that file, then the following command would show that firmware volume:
~/src/edk2$ VolInfo --offset 65536 path/to/FV/EDKUNIX.fd
~/src/edk2$ VolInfo --offset 64k path/to/FV/EDKUNIX.fd
~/src/edk2$ VolInfo --offset 0x10000 path/to/FV/EDKUNIX.fd
This (optional) file is built as part of the edk2 build process. It is generated in the FV directory alongside the firmware volume file. The VolInfo utility looks for this file alongside the input firmware volume file, and if found it will read its contents to define tools used for extracting GUID defined firmware volume sections.
Each line contains three tokens separated by whitespace. The three tokens are (in order):
1) the GUID associated with the tool,
2) a name for the tool, and
3) the path to the tool executable.
An example of a possible line from the file:
a31280ad-481e-41b6-95e8-127f4c984779 TIANO /path/to/TianoCompress
