Match box Make Linux machine of large size with Intel Edison

The challenge of making small computer of match box size where Linux runs using SD card size single board computer "Intel Edison" has begun.

I am trying to create a very small Linux machine,Ben MartinMr. Intel Edison is a perfect one-board computer for the IoT era, and its size is 35.5 mm in width × 25 mm in length, and it is a compact computer with almost SD card size. The CPU has dual-core Intel Atom, 1 GB memory, 4 GB storage and also has a Wi-Fi / Bluetooth chip. The IO relationship is consolidated on the connector on the back side.


Edison alone is difficult to handle, so use SportsFun Electronics's Edison outboard to increase storage or write programs. However, the rightmost display seems to have to be stacked on top so that the screen can be seen.


Unlike a general single board computer such as Arduino, Edison drives at 1.8V. Since Edison can not directly supply power,Base block of SparkFunWe are using a substrate called.


Connect to the Linux machine using the Micro-USB port and type "dmesg" command to check the location of the console. By default there is no password setting, just enter the console OK. Edison's on-chip storage is partitioned so that it can secure enough space to install Linux and applications,DebianSwitching is also easy.


Before using Yoct Linux, it is recommended to update to the latest firmware. In the Intel Edison Setup WizardFileYou can get.


With the Intel Edison Setup Wizard, you can use functions such as updating Linux distribution, setting the root password, setting Wi-Fi connection. Because Edison can scan and detect Wi-Fi SSID, Wi-Fi setup is very easy. In addition, it seems to be careful for updating the firmware that you need root privilege.


Martin says that one of the most important elements when using Linux on a small computer board is storage speed. So I am trying "bonnie ++" command to measure Edison's storage speed. However, while Edison has only 1.3 GB for 1 GB memory capacity, it does not work well because Bonnie ++ requires twice the size of RAM. The result below is likely to be the cache value of memory, not storage.


In addition, it seems that it took about 5 seconds to create 1,000 files in the built-in storage's home directory in order to check the speed at the experience level.


Martin is testing CPU performance by compiling and running OpenSSL 1.0.1e. The result is as follows and it is inevitable that teeth can not stand up to Intel Core i5-M430, but it is about 2 times faster than Raspberry Pi 2. However, you can also check that the memory speed is as low as half of Raspberry Pi 2. In the recompression test of tarball using gzip, Edison took 3 minutes 27 seconds, Raspberry Pi 2 took 2 minutes 52 seconds, so both machines seem to be close performance in the test using both memory and CPU.


Testing the power consumption of Edison, it is stable at the maximum of 0.16 A at boot and 0.06 A at idle. Since the voltage at this time is 5.16 V, the power consumption when idling is within 0.3 W or less. When sysbench moved the CPU with 2 threads, the current value was maximum 0.1 A. Martin said that he thought that it would be possible to use the lithium polymer battery properly even if conservatively estimated.

Martin will continue to defeat Edison for "match box size computer" in the future,Linux.comIt is said that it is going to announce it on above.


In addition, Intel Edison (pitch conversion board set) can be purchased with switch science at 9666 yen.
