The Raspberry Pi is one of the most popular single-board computer brands. Its popularity is partly due to the numerous unique and interesting projects people have created using the Raspberry Pi. People have used the Raspberry Pi in various projects and provided instructions so that others can recreate their projects. Below are the
LEDE project is a spin-off of the OpenWrt project and shares many of the same goals. We are building an embedded Linux distribution that is easy for developers, system administrators, or other Linux enthusiasts to compile and customize software for embedded devices, especially wireless routers. The name LEDE stands for Linux Embedded Development Environment.The project members include most of the
1、reboot means to restart.
2、source makes the modified files take effect immediately, avoiding the problem of having to restart for the changes to take effect. For example, if we modify /etc/profile, the changes will not take effect immediately. In this case, we can enter source /etc/profile to apply the changes.
There will be more updates in the future.
3、chmod -R 777 /home/edu/practice sets all file permissions in the practice folder to 777.
4、Compress a single file: gzip
Recently, I've noticed that many friends want to try the soft routing system OpenWRT. Today, we're starting to update various posts related to soft routing!
What is a soft router?
A soft router refers to using a desktop or server with software to create a routing solution, mainly relying on software settings to achieve the functions of a router; while a hard router uses specialized hardware, including processors, power supplies, and embedded software, to provide predefined router functions.

Hello everyone, I am the beloved Xiaoyue.
Recently, a fan asked me to introduce a new development board that supports windows & linux. After careful consideration, I decided to introduce the LattePanda Delta.
LattePanda Delta, mathematical symbol triangle △; it represents a compromise between design, performance, and price. It maintains a perfect

1. Positioning of Cortex-M
The architecture of the processor defines the instruction set (ISA) and the programmer model of the processor based on this architecture. In simple terms, application software under the same ARM architecture is compatible. From
You have a Raspberry Pi running Raspberry Pi OS, which used to be called Raspbian, and you surely know that it is a fantastic small computer with a great operating system that includes everything a beginner might want. However, once you
This section only records the general trimming method without introducing specific file modifications.
Linux Kernel Trimming Steps
1 Modify the ARCH and CROSS_COMPILE environment variables in the makefile
ARCH ?= arm
CROSS_COMPILE ?= XXX (your cross compiler)2 Find the configuration file xxxdeconfig in the arch/arm/configs folder, and modify it appropriately. Run the following in the root directory:
make xxxdeconfig3 Run make menuconfig in the root directory. If new content has been added in xxxdeconfig, Kconfig needs to be modified to match xxxdeconfig.
4 Run
When installing the system on the Raspberry Pi, the system is usually directly flashed onto the memory card. Although convenient, the inherent limitations of the memory card mean that its capacity and speed do not meet our requirements. To enhance the experience, we choose to install the system on an external hard drive to solve this issue. However, the Raspberry Pi defaults to booting from the TF card, so
