and port number via the kernel parameter kgdboe. The KGDB supports a multi-processing architecture that implements the KGDB core separately for each supported processor architecture.10.KGDB Remote Debugging Kernel program:① Configuring the Linux kernel: #make menuconfig into the Linux configuration menu--"Kernel hacking"--"Kgdb:kernel debugger"② Configuration Kernel Parameters: Enter the Uboot mode during the board boot process, set the Linux kernel boot parameters with the setenv command, and

this requires the Linux driver to output messages using the PRINTK function only during the development phase. The PRINTK function displays the message in the console through the/dev/console device file, which only works under the console of the character interface, so the PRINTK function is only used on the console of the character interface to output the message normally.In Linux file systems,/proc is often used as a tool for data interaction between kernel space and user space. /proc is a vi

. 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" to move the sensitive code that was originally in the Linux driver up a level, so that these sensitive code to get rid of the GPL protocol, those who do not want to open source Linux drivers are not necessary to open source.For some special requirements for some hardware, it may be necessary to access some user s

This chapter focuses on the hardware abstraction layer:HAL. Hal is built on Linux Drive A set of libraries,Google for Android to join HAL mainly for the purpose of the following. 1. Calling interface for unified hardware2. Fixed the issue of GPI copyright 3. For a number of special requirementsIn the LED driver, we joined HAL to use the program does not need to care about the Linux driver and device files interactive way. To write a Linux driver th

Android Deep Exploration ( volume 1) HAL with the Driver Development Section three Chapters git Getting started with reading notesThis chapter is an overview of Git. linux is an open-source system. In fact, in linux Many software is related to the underlying program and the kernel driver. , however linux The kernel has a lot of versions, If each version of the software is in the form of an installat

hit it all. The second kind of IDE looks for links, which refers to automatic compilation, excludes unused classes, but excludes the SDK.The third is to exclude class libraries that are not used in all assemblies.Note: For serialization and the underlying use of serialization, the link cannot be found and may be excluded from the use of the class, resulting in the program not being used.Workaround:You can exclude assemblies that you do not want to link.What effect does thin body have?I did not

debug user space. Quit is used to exit the GDB debugging interface; list is used to list the code in the program. Remote debugging of the user space program with Gdbserver is a service-side program that can run on an arm architecture. First enter the Android emulator terminal and then enter the Data/local directory. The Android emulator can only use the Gdbserver debugger through port mapping.Using KGDB to

Hardware Abstraction Layer: HALGoogle to join HAL for Android mainly has the following purposes:1. The calling interface of the unified hardware. Since HAL has a standard calling interface, HAL can be used to shield Linux drivers from 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. S

Git-is written by the father of Linux, Linus, is a software for source code control. Linus has designed git in a file system expert and kernel designer perspective, and its unique design allows git to have exceptional performance and optimized storage capabilities, and Git is superior to other similar source control software in every way. While learning about Android and the Linux kernel, there is a lot of source code involved in driving the developme

Test Linux drive: Test Linux drivers with Ubuntu Linux, test Linux drivers using the Android NDK, and use Java code to directly manipulate the device files for Linux drivers, Test the Linux driver by running an executable program on the S3C6410 board and compiling the driver into the kernel for testing. 3.
