This time I did it on a Mac. This is just a ** memo **, so don't expect a lot of information. ..
Anyway, if you don't do this, it won't start. Reference: Flashing Edison (wired) --Mac
If you have installed it, go to the next section. ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install dfu-util coreutils gnu-getopt
First download From Edison --Software Downloads, "[Edison Yocto complete image](http://downloadmirror.intel.com/24271] Download /eng/edison-image-ww36-14.zip "Linux image") "and unzip it.
Move to the unzipped directory
Start burning script ./flashall.sh Immediately after starting the script, it says "Please plug and reboot the board", so unplug and reconnect the USB. There is no need to operate the terminal because the re-insertion is automatically recognized. It takes about 5 minutes to bake, so wait slowly so as not to turn off the power.
screen /dev/cu.usbserial-A903BYAS 115200 -L The "-A903BYAS" part changes depending on the environment.
Once connected, press Return twice and the login prompt will appear. login> root And log in as the root user. No password required.
If the Arduino sketching process is running, the input is motivated and difficult to operate, so stop it with the following command. /opt/edison/sketch_reset.sh
cat /etc/version If the displayed version is build_68 or later, such as "edison-weekly_build_68_2014-09-08_13-49-07", it is OK.
configure_edison --setup If you enter, the setting will start, Wifi will be connected as soon as you set it. When the settings are complete, you will be told "Done. Please connect your laptop or PC to the same network as this device and go to http://192.168.0.9 or http://edison.local in your browser." Since you will be able to connect with SSH, work with SSH from here on.
If you only want to set up Wifi configure_edison --wifi Is fine.
From another terminal ssh [email protected] "Edison.local" is the address confirmed from the serial in the previous section. You will be asked for a password, so enter the one you just set.
rm /etc/localtime After erasing the existing settings with
ln -s /usr/share/zoneinfo/Asia/Tokyo /etc/localtime To match Tokyo / Japan.
The package manager for Yocto Linux seems to be called opkg.
vi /etc/opkg/base-feeds.conf Start vi with
src/gz all http://repo.opkg.net/edison/repo/all src/gz edison http://repo.opkg.net/edison/repo/edison src/gz core2-32 http://repo.opkg.net/edison/repo/core2-32

Since the capacity under __ / __ of Edison is not allocated so much, install the tools and libraries under __ / home / __ where 2.2GB and more than half the capacity of eMMC are allocated.
vi ~/.profile Start vi with
export PATH=~/.local/bin:$PATH
Enter. Now, the applications placed in this directory will be searched preferentially.
After inputting source ~/.profile Then, enable the setting. (Or re-login) If you enter export in the command, you can see that the PATH is set.
** Oh, this is no good. Edison's memory capacity is too small and it stops halfway. .. Build a cross-build environment. ** **
Install the packages required for build with opkg. opkg install libgmp-dev libmpfr-dev libmpc-dev

Introducing Automatically Tuned Linear Algebra Software (ATLAS). An implementation that automatically tunes each CPU architecture of BLAS, which is a linear algebra high-speed arithmetic library. BLAS is often required for libraries specializing in calculations (such as SciPy), so I will include them here.

Build make build If you try to build in parallel here and enter "-j2", an error will occur. It takes a transcendental time (12 hours or more!) To try various optimization patterns. nohup make build > ./make.log & Then, the build will continue even after logging out, and the log will be written to make.log, so it is better to quickly disconnect the communication with the mother ship and leave it all day with only the power supply.
Installation make install I get an error saying that libf77blas.a does not exist, but it seems that libatlas.a, libcblas.a, liblapack.a, libptcblas.a have been installed. By the way, make check cannot be done because libf77blas.a does not exist.

Make it an access point, make it Beacon / iBeacon, or install Node-Red It seems that you can also install Java. https://communities.intel.com/docs/DOC-23391
