Give developers a bug report, and they will fix one bug

Give them a way to run test, and they will fix bugs all their life

This project wants to provide a tool for RIOT developers to easily run tests on their HW (multiple development boards).

Instead of having boards sitting on a desk or a shelf, plug in to a machine that will allow easily running tests on all those boards. Use a different machine than your personal machine, that way running tests doesn't mean halting or slowing down your own work.

The goal would be for all tests to be run on most boards at least every release, ideally every week and make this results easy to share with other RIOT developers.

Why don't I plug my boards into murdock? You could but this means relinquishing ownership of your board to the CI. This also means setting up 1 RPI per board... hmm maybe not what I want.

Why don't I use philipp? You can of course do this, it will enable another level of testing, complementary. You still need to have a setup that allows running those tests on multiple boards. How RIOT HIL handles this is with 1 RPI per board... we don't want this.

To be able to scale we need to map multiple boards and be able to easily flash and test the desired boards.

We will use udev rules to define SYMLINKS between the boards serial port (dev/tty-board-name) and the actual serial port(dev/ttyACM* or other). With this we can query the rest of the boards serial dev information (DEBUG_ADAPTER_ID, PORT, etc.) to always flash and open a terminal on the correct port.

The logic for this will be in makefiles.pre.

PORT = /dev/riot/tty$(BOARDDEF)
DEBUG_ADAPTER_ID = $(\
    shell udevadm info -q property $(PORT) |\
    sed -n ’/ID_SERIAL_SHORT/ {s/ID_SERIAL_SHORT=https://p}’)

A local configuration will allow flashing and testing on boards on your remote machine remotely makefiles.pre.

  override FLASHER = ssh
  override FFLAGS = $(RYOT_CI_SERVER) 'IMAGE_OFFSET=$(IMAGE_OFFSET) \
    $(RYOT_CI_MAKE) flash-only FLASHFILE=$(RYOT_CI_FLASHFILE)'
  SSH_UPLOAD = rsync --chmod=ugo=rwX

  define flash-recipe
    $(SSH_UPLOAD) $(FLASHFILE) $(RYOT_CI_SERVER):$(RYOT_CI_FLASHFILE)
    $(FLASHER) $(FFLAGS)
  endef

  RESET              = ssh
  RESET_FLAGS        = $(RYOT_CI_SERVER) '$(RYOT_CI_MAKE) reset'
  override TERMPROG  = ssh
  override TERMFLAGS = -t $(RYOT_CI_SERVER) '$(RYOT_CI_MAKE) term'

tribe team in Inria has 20+ boards and for a developer flashing on any board is as easy as:

RYOT_CI=1 BOARD=<board> make -C examples/hello-world flash test
