因为现在都不知道怎样走,学习方向有

1. Top-Down Approach
这个估计比较简单,因为很多东西都是前人已经做好,而很快看到效果,但是要深入就要再往下层看。

2. Bottom-Up Approach
这个在Bootloader开始,然后再往上走,例如OS image等等。

不知道大家有什么preference呢?

Why not project-oriented?

Just "learn" without direction would not last for long.

The question is what is the final project(product)? Dream VOIP device?

My objectvies are as follows:

The final goal is to able to use Qt to perform the task that I want but it includes the followings:

1. Circuit design of an ARM-based system
2. Modification of U-Boot based on my developed system
3. Customisation of Linux kernel to fit my target system
4. Development of the corresponding device drivers to fit our needs
5. Installation of Qt (QML or other versions) package for graphical output
6. Development of USB/Ethernet network for communicating with user application and storage of user application in the flash. The user application may be in the form of QML and other devices of the target system

1. I think leave this job to electronics designer.
2, 3, 4 are related to bottom-Up.
5, 6 seems a big jump from 2-4, all base on high-level programming.

The basic issue is LINUX programming...
