-# This file is intended to be used as a .gdbinit for an EC debugging session.
-# It defines some useful functions for analyzing the EC state.

-# Setup Automatic Import:
-# ln -s util/gdbinit .gdbinit
-#
-# Environment Variables:
-# BOARD=[nocturne_fp|bloonchipper|...]
-# GDBSERVER=[segger|openocd]
-# GDBPORT=[gdb-server-port-number]
-#
-# Warning, this is a working collection that is not guaranteed to function
-# properly on all platforms. The ec-tasks functions is a good example of a
-# function that works well on most simple platforms, but may have issues on
-# platforms with data cache enabled.
-#
-# Note, this file must maintain space indention to allow easy copy/paste
-# while in active debugging. Using tabs interferes with the embedded python
-# during copy/paste.
