beaglebone black memory

Beaglebone Black Quick Start Tutorial 1th Chapter embedded Linux for the makerMaker's Chinese meaning is similar to "maker". A creator is a group of people with a passion for technology and practice, sharing technology and exchanging ideas for pleasure. But in order to keep maker's original flavor, we use the English maker in unison here. Maker Culture is an extension of the DIY (do IT yourself) culture, wh

My Beaglebone black before installing the Ubuntu 14.04 System, the use of the process found in the Ubuntu system under the serial device TTYS1~TTYS5 can not be used, open the serial port will show input/output error, I guess there may be no driver or any other reason, younger brother compared vegetables, so did not find the reason, also did not solve.My solution is to brush back to the factory is the operat

This time with SPI. BBB is available in two sets of SPI interfaces, both of which are default disable and need to be enabled in overlay mode, i.e.: echo bb-spidev0 >/sys/devices/bone_capemgr.9/slots My BBB current configuration is currently configured/opt/source/userspace-arduino/overlay/bb-spi0-01-00a0.dts/dts-v1/;/plugin/; / {compatible = "Ti,beaglebone", "Ti,beaglebone-

Use the miniUSB line to link the board and the computer, and then under "My Computer" there will be a beaglebone getting started disk, under this directory found a folder named "Drivers", Under this folder to find the corresponding operating system of the program, installation. If there is a prompt to trust the manufacturer's driver of a kind of prompt box, all choose Trust (do not trust the words can not play ....) ) until the prompt driver installat

who have to do rookie, rookie not scary, afraid of is no one to guide the direction of progress! This series of articles will describe the basic use of each function module of BBB. There are too few BBB data in Chinese now, they are collected from all corners of the internet in the world, learned, personally tested experience summary. To share with you, I hope everyone (especially beginners) in the BBB to get started on the road to some smooth!I will be here to update the list of articles at any

Many people are learning about the Linux operating system. We encounter many problems when learning Linux. I recently looked at Linux memory management and saw that the red/black tree was very big. So I learned the basic knowledge of the red/black number. Linux memory management is explained in detail. The red-

My machine is configured with Intel Core 2 4320CPU Kingbang black Kong 2G DDR2 800*2 P965P-DS3 Motherboard N 8600GTS In Vista, I only recognized 3.5 GB. I upgraded the master BIOS to support a maximum of 8 GB... The current system does not support 4 GB memory. Generally, only 64-bit XP can be changed. So there is no good way for you. 1. Memory addressing capabil

saved? Of course not, a simple example: a 3-layer neural network, we can not save the results of the second layer, when the BP to the second layer needs its results, can be calculated by the results of the first layer, which saves a lot of memory. To remind you, this is only my personal understanding, in fact, this article paper has not been to a good read, have time to take notes again. But the general meaning is almost like this.　　Second, how? 　　Ho

The Linux kernel uses red-black trees to maintain memory
