Prerequisites

Build Walkthrough

1. Follow the instructions in the documentation (skip the last step make jenkins_run)

2. Clone the genode-world under genode/repos (assuming you are in the operating-system directory)

git clone https://github.com/argos-research/genode-world.git genode/repos/genode-world
cd genode/repos/genode-world
git checkout protobuf_3.5.0

2.1 Clone the pololu Servo Controller

git clone https://github.com/argos-research/genode-pololuServoController.git genode/repos/genode-pololuServoController

3. Clone this repository into genode/repos (assuming you are in the operating-system directory)

git clone https://github.com/dk87/genode-CarControl.git genode/repos/genode-CarControl

4. Create a build directory for a rpi, pbxa9 and a panda build

GENODE_TARGET=focnados_rpi make jenkins_build_dir
GENODE_TARGET=focnados_panda make jenkins_build_dir
GENODE_TARGET=focnados_pbxa9 make jenkins_build_dir

5. Edit the etc/build.conf in each build directory by adding the following lines

REPOSITORIES += $(GENODE_DIR)/repos/genode-world
REPOSITORIES += $(GENODE_DIR)/repos/genode-CarControl
REPOSITORIES += $(GENODE_DIR)/repos/genode-pololuServoController

6. Prepare the missing ports by executing (again in operating-system directory)

./genode/tool/ports/prepare_port libmosquitto openssl libprotobuf

7. Trigger the compilation

make -C build/genode-focnados_rpi app/servo_client app/mbl_client
make -C build/genode-focnados_panda app/servo_adapter app/mbl_adapter
make -C build/genode-focnados_pbxa9 app/savm app/acc

Run-time Instructions

1. Use the ACC branch of speed-dreams (ref.)
2. Configure a race to consist of two bots, with the ACC driver in the second position
3. Start a mosquitto server
4. Bring up all applications (acc, mbl_adapter, mbl_client, servo_adapter, servo_client) except for the savm
5. Start the savm application
6. Speed-dreams should continue loading and start the race
7. Watch the magic happen

Additional information

• SpeedDreams uses the 9002 port by default and acts as a server
