# A script to diff between two ram or rom reports generated by
|
|
# size_report. When you call call the ram_report or rom_report targets you
|
|
# end up with a json file in the build directory that can be used as input
|
|
# for this script.
|
|
|
|
# The output shows which symbols insreased and which decreased in size and
|
|
# also tracked added/remove symbols as well.
|
|
|
|
# Example:
|
|
# ./scripts/footprint/fpdiff.py ram1.json ram2.json
