cmd_load_symbols.py can only load symbols from FV. Add the possibility to use UEFI console output to calculate dll load address and send add-symbol-file commands directly to ArmDS debugger dll load address can't be used directly from UEFI output, see comment in DebugPeCoffExtraActionLib: "This may not work correctly if you generate PE/COFF directly as then the Offset would not be required". 1) Use objdump -S module.dll | grep <_ModuleEntryPoint> to get offset in dll (offset) 2) Use Entrypoint=<address> from UEFI console output (entrypoint) 3) dll load address is (entrypoint)-(offset) Signed-off-by: Artem Kopotev <artem.kopotev@arm.com> Tested-by: Pierre Gondois <Pierre.Gondois@arm.com>
