Ard, I got a pretty much the same issue when I tried to do some debugging in
the ShellPkg.
Except Shell I can perfectly debug everything.
1. source / uefi/ArmPlatformPkg/Scripts/Ds5/cmd_load_symbols.py -f
(0x85000000,0x00280000) -m (0x80000000,0x40000000) -a
loads symbols fine, but does not recognize any module matching the current
PC if stopped in the shell.
2. Loading symbols with "add-symbol-file
/uefi/Build/NS2Pkg/DEBUG_GCC49/AARCH64/ShellPkg/Application/Shell/Shell/DEBUG/Shell.dll
0xB6926000"
"recognizes" modules (wrong ones though) but the source code does not match
disassembly.
So with Shell debug using DS-5 the code does not match the source.
Is there a special linker setting I am missing or a technique?
I am using the latest UEFI code from
https://github.com/tianocore/edk2.git
Thank you,
Vladimir
