[Q]Could somebody explain my the design/organization from an android-system

---

Hello,

wich are the components from an android on a HTC HD2.
There are different types like Kernel, Moduls, etc...
But where can I find it and understand how they work together.
What I found:

• zImage includes the Kernel for the complete system
• startup.txt includes the parameter how to start the system
• CLRCAD.EXE is used for the sound in android
• HaRet.exe is used to start/boot the android

Is this correct? What I can't assign is:

• the ROM on which the release based - can I see the files on my SD or is this included in other files?
• the modules like WiFi and so on (maybe here /system/lib/modules)?

The next questions would be:

1. Could I use a new kernel with an existing system (Only with changing the existing zImage-File and unsing a modified startup.txt)?
2. Could I update seperate moduls without install new system? (new version for WiFi or GPS or else)

The kernel is the core of any linux based os, some base drivers are included in kernel and other linkes as modules, if you install a new kernel that don't need any external module you can simple copy zImage, if new kernel need new modules you have to copy into /system/lib/modules directory. Modules are related to kernel you cannot update modules without apdate kernel.
