corresponding message at the console. The PRINTK function displays the message in the console (also known as a terminal) through the/dev/console device file, which functions only under the console of the character interface, so the PRINTK function is only used on the console of the character interface to output messages normally.In Linux file systems,/proc is often used as a tool for data intersection =ee of kernel space and user space. The/proc file system behaves like a device file system C/d

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 Gdbserve

This chapter provides a detailed introduction to the Minicom Serial debugging tool, which includes 4 steps, and requires Eboot erase Nandflash before burning the Android system into 5 steps. Now there are a variety of development boards on the market, we should grasp the method based on a detailed understanding of the differences between the different development boards.This chapter also learns about the Development Board test environment, because we

Android Deep Exploration (Vol. 1) HAL and Driver development experienceThe tenth chapter of embedded Linux call technologyFor complex Linux drivers and libraries such as HAL, you need to debug them in a variety of ways. For example, set breakpoints, step through code, output debugging information, and so on. While embedded Linux is not easy to

Detailed analysis of the android GSM Driver Module (rild) (2) request process Please note that pandatv posted on it168 and opendroid 1. Operation of multiplexing I/O MechanismAs mentioned above, requests are received through multiplexing I/O in ril_event_loop, and Initialization is also analyzed. Now let's take a closer look at how this mechanism works.Ril_event_set is responsible for configuring an event

Embedded Linux debugging technology, for the complex Linux driver and Hal and other libraries, need to use a variety of methods for debugging, such as setting breakpoints, gradually tracking code, output debugging information. This chapter focuses on how to debug embedded Linux kernel modules, executables, and shared libraries using the Development Board, Android

In the hardware/RIL directory, the ril driver module of Android is divided into three parts: rild, libril. so, and librefrence_ril.so, and radiooptions are available for automatic or manual debugging. All depend on the ril. h header file in the include directory. Currently, the cupcake branch is equipped with gsm support and the cdma branch. The gsm driver is ana

The previous initialization process has been analyzed. After Initialization is complete, three event objects are attached to the queue:S_listen_event: socket named rild, main requeset response channelS_debug_event: socket named rild-debug. requeset response channel is use
