If you can read this, you're not using a version control system affected by
this change ;)
Before: make -d | wc -l ==> 992
After: make -d | wc -l ==> 452
Instead of just adding elf/bin and friends, actively delete the original
suffixes and include only things we care about.
Before vs After:
make -d | wc -l ==> 4497
make -d | wc -l ==> 932
Now, if only I could turn off the RCS/SCCS support so easily.
This introduces the first firmware setup specifically for automated testing.
Based heavily on the linux kernel project's "USB Gadget Zero" idea, and in
theory, this should be testable with <kernelsrc>/tools/usb/testusb.c but...
not yet. It's tricky to set that up and poorly documented, so we've got our
own tests instead. Instead, we include a set of python unit tests using pyusb.
These currently only test a basic core subset of functionality, but have already been
very helpful in finding latent bugs.
In this first stage, we support only the stm32f4 disco board, (MB997) and
FullSpeed USB devices. A generic "rules.mk" is introduced to support multi
platform builds. (See below)
Some basic performance tests are included, but as they take some time to run,
you must manually enable them. See the README for more information
NOTE! Only the source/sink functional interface is supported, loopback will require
some comparision with a real gadget zero to check exactly how it's working.
FOOTNOTES 1:
This introduces a rules.mk file that is arguably substantially simpler[1] for
re-use, and then uses this rules.mk file to support multiple target outputs
from the same shared source tree. Less path requirements are imposed, and less
variables need to be defined in each project's makefile. A separate bin
directory is created for each project.
All useful settings and configurations imported from the original library rules
file.
cxx support untested, but lifted from the original library rules file.
[1] Than the file in the libopencm3-examples repo it is loosely based on.
