After having applied a patch to fix how the RPi folks implemented the FIQ system the kernel compiled without issues: Linux raspberrypi 4.9.33-rt23-v7+ #2 SMP PREEMPT RT Sun Jun 25 09:45:58 CEST 2017 armv7l GNU/LinuxĪnd the RPi seems to run stable with acceptable latencies: Histogram of the latency on the RPi with a real time kernel during 300000 cyclictest loops

Well, that’s not the case so after having compiled a first real time kernel the RPi froze as soon as I tried to run apt-get install rt-tests. I compiled real time kernels for the RPi before but you had to jump through some hoops to get those running so I hoped things would have improved somewhat.
Flashed an SD card with Raspbian Jessie Lite and started to do some research on the status of real time kernels and the Raspberry Pi because I’d like to use a real time kernel to get sub 5ms system latency. So first I need to set up a sidecar device and I sacrificed one of my RPi’s for that, an RPi 3. I’m thinking about building a kind of sidecar device to offload some stuff to using netJACK, think of synths like ZynAddSubFX or other CPU greedy plugins like fat1.lv2. This opens a plethora of possibilities of course. The MOD Duo can run as a JACK master and you can connect any JACK slave to it as long as it runs a recent version of JACK2. Installing Linux on a RK3066 based deviceĪs a beta tester for MOD I thought it would be cool to play around with netJACK which is supported on the MOD Duo.Jake on Using the Tascam US-144MKII with Linux.Using Home Assistant with IR controlled devices.
