Configure memory split

You'll need to bump up the memory made available to the GPU. Increase the default value of 64 to 256.

• Via raspi-config tool

You can adjust the memory split by running the raspi-config tool. See the official documentation

• Editing /boot/config.txt

You can adjust the value directly by editing the /boot/config.txt file.

> sudo nano /boot/config.txt

Find the line containing gpu_mem=64 and change the number to 256

gpu_mem=256

Installing the RaceCapture app package

Download the latest RaceCapture app package and place it in the /opt/ directory of the Raspberry Pi.

• Directly downloading to the Raspberry Pi

You can download it directly by getting the URL of the package by right-clicking the download link and copying the URL to your clipboard. Then, use it in the command below:

cd /opt
sudo wget <package URL>

Extract the package

Now extract the downloaded package :

sudo tar -xjvf <downloaded file>

Launch the app

Launch the RaceCapture app by running the following command:

/opt/racecapture/run_racecapture.sh

Launching with Watchdog

You can launch the RaceCapture app with an automatic watchdog that re-launches the app in case a crash occurs.

/opt/racecapture/run_racecapture.sh -w 1

• Note: to break out of the watchdog loop, press ctrl-z to suspend the app, then issue:

killall -9 run_racecapture.sh
