[Sequence] Learning
Linux

I have been developing in this area for nearly a year. As I was the first in the lab to develop in this area, I encountered many problems during the learning process. However, I always had no choice but to find my own solutions, at the same time, it also makes full use of the network and provides reference
Csdn

Thank you for your post on Boyou and related forums!
 

 

Embedded
Linux

Learning covers a wide range
Bootloader

, To kernel transplantation, file system, intermediate driver development, to the upper layer of application debugging, development environment, and so on, unpredictable, often others can use their own problems.

 

Due to lack of proper guidance from others, I have also taken many detours in the learning process, and the entire development environment has been set up.
N

For a long time, I often hear that modules are loaded.
Insmod

Can the command be connected to the host or
Arm

I don't know what it means. It's a sweat! Don't laugh, embedded
Linux

Beginners do not understand the cross-environment. I am one of them.

 

Now it's time for friends to learn embedded
Linux

I summarized my learning experience over the past year and organized an overall learning plan, hoping to help those who once looked at me. This document will be improved later, uploaded to the personal space, and the directory will be pasted first. I am at a limited level. If not, please correct me!
