Bill, The Python tools can tend to throw vs.flagging errors in the config files. Did you happen to edit anything in *.inf,*.dsc, or *.fdf files? This could just be a syntax error in those changes. This error looks like trying to make the FV (Firmware Volume) and Ffs would be one of the files in the FV, and the file is built out of sections. > OSError: [Errno 2] No such file or directory: '/.../vendor/BOOT.MXF.2.0/boot_images/Build/ClarenceLAA/Core/RELEASE_CLANG120LINUX/FV/Ffs/1C04F529-0612-4319-9315-B2E75C16810AFeatureEnablerDxe/1C04F529-0612-4319-9315-B2E75C16810ASEC2.1.pe32' Thanks, Andrew Fish PS FYI Python 2.7 is no longer supported as of January 1st, 2020. > On Apr 4, 2024, at 5:13 AM, Bill Shih 施炫全 via groups.io wrote: > > Hi Sir > > I have problem when building android bootloader. > > The log suggested I could mail you for help. > > Can I have your suggestion to solve this error? > > Thank you > > The log: > > build.py... > : error C0DE: Unknown fatal error when processing [/.../vendor/BOOT.MXF.2.0/boot_images/boot/***/Library/EblCmdLib/EblCmdLib.inf [AARCH64, CLANG120LINUX, RELEASE]] > > (Please send email to devel@edk2.groups.io for help, attaching following call stack trace!) > > (Python 2.7.18 on linux2) Traceback (most recent call last): > File "/.../vendor/BOOT.MXF.2.0/boot_images/edk2/BaseTools/Source/Python/build/build.py", line 2599, in Main > MyBuild.Launch() > File "/.../vendor/BOOT.MXF.2.0/boot_images/edk2/BaseTools/Source/Python/build/build.py", line 2394, in Launch > self._MultiThreadBuildPlatform() > File "/.../vendor/BOOT.MXF.2.0/boot_images/edk2/BaseTools/Source/Python/build/build.py", line 2234, in _MultiThreadBuildPlatform > Wa, self.BuildModules = self.PerformAutoGen(BuildTarget,ToolChain) > File "/.../vendor/BOOT.MXF.2.0/boot_images/edk2/BaseTools/Source/Python/build/build.py", line 2109, in PerformAutoGen > CmdListDict = self._GenFfsCmd(Wa.ArchList) > File "/.../vendor/BOOT.MXF.2.0/boot_images/edk2/BaseTools/Source/Python/build/build.py", line 2006, in _GenFfsCmd > GenFfsDict = GenFds.GenFfsMakefile('', GlobalData.gFdfParser, self, ArchList, GlobalData) > File "/.../vendor/BOOT.MXF.2.0/boot_images/edk2/BaseTools/Source/Python/GenFds/GenFds.py", line 544, in GenFfsMakefile > FvObj.AddToBuffer(Buffer=None, Flag=True) > File "/.../vendor/BOOT.MXF.2.0/boot_images/edk2/BaseTools/Source/Python/GenFds/Fv.py", line 127, in AddToBuffer > FileName = FfsFile.GenFfs(MacroDict, FvParentAddr=BaseAddress, IsMakefile=Flag, FvName=self.UiFvName) > File "/.../vendor/BOOT.MXF.2.0/boot_images/edk2/BaseTools/Source/Python/GenFds/FfsInfStatement.py", line 518, in GenFfs > InputSectList, InputSectAlignments = self.__GenComplexFileSection__(Rule, FvChildAddr, FvParentAddr, IsMakefile=IsMakefile) > File "/.../vendor/BOOT.MXF.2.0/boot_images/edk2/BaseTools/Source/Python/GenFds/FfsInfStatement.py", line 969, in __GenComplexFileSection__ > SectList, Align = Sect.GenSection(self.OutputPath, self.ModuleGuid, SecIndex, self.KeyStringList, self, IsMakefile = IsMakefile) > File "/.../vendor/BOOT.MXF.2.0/boot_images/edk2/BaseTools/Source/Python/GenFds/EfiSection.py", line 321, in GenSection > IsMakefile=IsMakefile > File "/.../vendor/BOOT.MXF.2.0/boot_images/edk2/BaseTools/Source/Python/GenFds/GenFdsGlobalVariable.py", line 502, in GenerateSection > if (os.path.getsize(Output) >= GenFdsGlobalVariable.LARGE_FILE_SIZE and > File "/.../vendor/BOOT.MXF.2.0/boot_images/edk2/BaseTools/Source/Python/Common/LongFilePathOsPath.py", line 21, in getsize > return os.path.getsize(LongFilePath(filename)) > File "/usr/lib/python2.7/genericpath.py", line 57, in getsize > return os.stat(filename).st_size > OSError: [Errno 2] No such file or directory: '/.../vendor/BOOT.MXF.2.0/boot_images/Build/ClarenceLAA/Core/RELEASE_CLANG120LINUX/FV/Ffs/1C04F529-0612-4319-9315-B2E75C16810AFeatureEnablerDxe/1C04F529-0612-4319-9315-B2E75C16810ASEC2.1.pe32' > > > -
