To parse your FV file (embedded in your FD file), you can use './BaseTools/BinWrappers/PosixLike/VolInfo <location of your FV file>'
If you want to debug the early stage of your UEFI boot process, you can only use (you do not need -m (...,...)): source edk2/ArmPlatformPkg/Scripts/Ds5/cmd_load_symbols.py -f (..,...) -a -v At the early stage of the boot, the UEFI firmware has not loaded its binaries into DRAM yet. The UEFI System Table will not be found in System Memory. Where your UEFI firmware lives when started? In DRAM or in Flash/ROM memory? > -----Original Message----- > From: Sharma Bhupesh-B45370 [mailto:b45...@freescale.com] > Sent: 23 October 2013 06:33 > To: Olivier Martin; edk2-de...@lists.sourceforge.net; 'Andrew Fish' > Cc: 'Kim Phillips'; boot-architecture@lists.linaro.org; Kushwaha > Prabhakar-B32579 > Subject: RE: [edk2] Debugging Sec and PI phases {Source symbols} > > Hi Olivier, > > I tried to use the DS-5 scripts, but landed in some issues, like: > "System table not found in System Memory". > > It seems there is some issue with the .FD gets generated for my > BoardPkg. > > I am also now trying to understand if there is some documentation/tool > available that > can parse my .FD and .FV files and can tell me about the sections in > this particular output > file.
