not able to load an elf file using the argument --elf-load

[jeebujacob]

Dear Olof,
I tried installing fusesoc fresh on my crashed pc, and now, after installation, the elf-load argument is failing, throwing a fusesoc error as an unrecognised argument.

Reference:

Hi Jeebu,

This is actually working as intended even though I realize it's not very intutive :)
--elf-load is a runtime argument intended for the simulation engine (that is converted to a verilog plusarg), so it has to be specified after the system keyword. In general it's like this
fusesoc <system/core> <system/core-specific arguments>
global arguments are currently only --cores-root to add extra repositories
action can be for example build or sim
action-specific arguments can be --force or --build-only for the sim action
core/system-specific arguments are those you will find when you run fusesoc sim --help

Hope this helps. The github issues page is starting to turn into the most comprehensive documentation so far :)
