While trying to reach a minimalistic image in order to run the RARE software, for now we only managed to have a 5Gb image (with INTEL SDE installed). We are confident that we can still slimmed down the image but times is running against us.  The very initial Mion image has a size of 45Mbytes ! |

| Even if the build process can be long depending on your build host, build duration can reach 30 minutes with a 32 cores machines. Subsequent builds will take significantly less time as a cache mechanism will avoid to to redo the whole build process. Believe me, you are done ! Just wait the end of the build process and grab the freshly baked image. |

| And in just 1 minutes you minute  you have installed a minimalistic OS on your bf2556x-11t. In this post we will stop here. However, in order to finalise the installation you'll to install INTEL P4 Software Development Environment as of course you'll want to run your P4 program on the bf2556x-1t. We will cover this subsequent installation in a subsequent post. |

- how to build Mion
- how to install Mion (process is the same on every ONIE based system: we tested bf2556x-1t, bf6064x wedge100bf-32x, wedge100bf-64x)
Please let us know if you want us to test your P4 platform with the RARE P4 software. We will then add it to the RARE Hardware Compatibility List (RARE HCL) !
(In that case you might have to arrange access to your P4 equipment or better ... Send us a sample ! )
| Tip |

Mion build is quite straightforward. As it share its root from Yocto, adding specificities related to your project is easy. Most probably a Bitbake recipe already exist and you'll just have to add a reference to the layer of your interest in Bitbake config file. First time build can be long and tedious if you have a small build host machine but subsequent build will be faster thanks to the sstate cache mechanism. Last but not least, we covered only the base OS installation, now that you have a minimal OS required to manage your machine, you need to add specific drivers and software needed to run P4 programs on APS or WEDGE platform. |
