Libmraa on ROCK Pi S
Package libmraa-rockpis is in Radxa APT bionic-testing and stretch-testing repositories.
Below is the instructions of how to install libmraa and use it.
Install essential packages
Edit file /etc/apt/sources.list.d/apt-radxa-com.list and add the following:
For Debian Stretch
deb http://apt.radxa.com/stretch-testing/ stretch main
For Ubuntu bionic
deb http://apt.radxa.com/bionic-testing/ bionic main
Get the pub key
wget -O - apt.radxa.com/stretch-testing/public.key | sudo apt-key add -
Update
sudo apt-get update && sudo apt-get upgrade
Install essential packages:
sudo apt-get install -y rockchip-fstab && sudo apt-get install -y rockchip-overlay && sudo apt-get install -y rockpis-dtbo
Install the latest u-boot and kernel:
apt-get install rockpis-rk-u-boot-latest
Manually run the u-boot flash script
/usr/local/sbin/rockpis_upgrade_bootloader.sh
Type YES to perform the uboot.img flashing.
Install kernel
apt-get install linux-base apt-get install linux-4.4-rockpis-latest
After installation, check file /boot/extlinux/extlinux.conf. It lists all kernel version installed in ROCK Pi S. The kernel corresponding to the first label is the newest version and the first boot option.
Install libmraa-rockpis
apt-get install libmraa-rockpis
Enable interface
