In short, the hardware abstraction layer of Android encapsulates the Linux kernel driver and provides interfaces up to shield implementation details at the lower layer. That is to say, the hardware support is divided into two layers: one layer in

When loading the XP Virtual Machine operating system in VirtualBox, the following error occurs: cocould not read from Boot Medium! System Halted or the following figure shows an error: cannot read from the startup media, and the System stops! The
1The HAL program must have a hal-module-info--sym (hw_module_t) variable that can be called by the Android System. Similar to (the C Function's main () and the Linux driver's init () function) 2 HAL programming is a three key structure:struct
The fifth chapter mainly studies the test environment of building s3c6410 development Board. The first thing to know is that s3c6410 is a low-power, cost-effective RISC processor that is based on the ARMI1 core and is widely used in mobile phones
The framework 1 involved in Android telephony is shown in.
Figure 1 Android telephony Framework Structure
Figure 1 shows some rules of the android telephony framework structure.
Android telephony's business applications span AP and BP. AP and BP communicate with each other, in line with the basic structure of the smartphone hardware described above.
The Android system runs on the AP, while Telephony runs on the user space on the Linux kernel.
Android telephony also adopts a layered structur

Some basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open-source systems. Due to my Fixed Thinking and insufficient acceptance of new things, I always use old thinking to learn Fedora Core 4.0; for mobile storage, such as USB flash drives, mobile hard drives, and digital cameras, most plug-and-play a

Preface:I am not a developer, not a master, or I love to play. In terms of technology, there is nothing like to explore, but to be opportunistic. In this article, you cannot "get out of work" and use my robot to change your own robot. Because you think the program is stinking, you cannot open source. However, if you have some knowle

Why Add HAL to Android1. The calling interface of the unified hardware. Because HAL has a standard calling interface, HAL can be used to mask Linux to drive complex, non-uniform interfaces.2. Fixed the GPL copyright issue. Because the Linux kernel is based on the GPL protocol, Android is based on the Apache Licence 2.0 protocol. So Google played a "traversal", mo
The way to add files in a U disk hidden partition:
Note: USBXP, drive, cdlinux file size of 800M, mobile hard disk or large U disk recommended partition larger! Partition format NTFS should be fine!
If prompted, click "OK" or "yes".
Because you have just divided 2 partitions, only one partition can be displayed under Windows! Therefore, you must set the visible partitions (the final need to hide the partition first set to visible, easy to copy files in, after the operation, set another pa
Linux system: the code that accesses the hardware register and the business logic code. There is no secret to the code that accesses the hardware registers, as this is a standard operation for calling the standard functions of the Linux kernel (ioread32, iowrite32, and so on). Some enterprises or individuals do not want to expose the source code, while the Linux-driven business logic is part of the strike. Although these Linux drivers are free for users, the implementation of these Linux driver
