The Linux Development Board requires several conditions to turn on the Telnet service:1. File system support TelnetBusyBox default is to put the Telnet and telnetd function into the, so this step is generally saved.2. Mount DevptsTo mount the filesystem, you need to create the PTS folder under the Dev folder and mount it as a devpts type. mkdir/dev/ptsmount-t devpts devpts/dev/ptsThese two steps can be writ

This article is based on the previous TQ2440 Development Board learning Documentary (1)-The simplest independent running assembler evolved. 0 arm Stack (stack) Basics ARM supports a full minus type stack, meaning that the stack pointer sp (that is, R13) always points to the data unit that just entered the stack. The corresponding to the full is dissatisfaction, this type of stack pointer sp points to the n

Learning database in recent time, because of their own needs, so pay attention to the point embedded SQLite database, SQLite, a lightweight database that complies with acid's relational database management system, is designed to be embedded and is currently used in many embedded products It takes up resources very low, in the embedded device, may only need hundreds of K of memory is enough. It can support Windows/linux/unix and so on the mainstream operating system, At the same time can be co

This article focuses on how the Arduino Development Board works from a hardware perspective. Most of the articles are about Arduino software. However, an in-depth understanding of its hardware design can help you take a solid step in the Arduino journey. Mastering the electronic design of the Arduino hardware will help you learn how to embed Arduino into the design of your final product, including which pa
