It's strange that the Release 1.6 + RTPATCH that I applied on Intel Edison is missing these two crucial commands to set a cpu affinity for a real time task. Just wondering whether I missed any additional configuration while building the kernel? Thanks.
The image do not includes those commands. You can add the required packages for this while building the image, or once that has been built it you can install the packages from source. Let us know which BSP are you using and from where are you getting the patch.
