                Installing the Machinekit Altera CycloneV test image
              
          
    Contents

This SD image is a debian jessie console image with:

a 4.1.22-ltsi-rt kernel with RT-PREEMPT patches applied
tested on Terasic DE0-Nano-SoC Kit, other SoCKit platforms should work with appropriate dtb
machinekit RIP-build under /home/machinekit/machinekit, all build artefacts are in place (no need to run make)
machinekit packages are NOT installed and you do not have to!
all machinekit build- and runtime required packages ARE installed.
/home/machinekit/.bashrc already set up to run machinekit from the RIP build directory.
one known-to-work configuration with hostmot2/onboard FPGA support is: machinekit/configs/hm2-soc-stepper/5i25-socfpga.ini
