Debugging by printing - eLinux.org
Probably the simplest way to get some debug information from your kernel code is by printing out various information with the kernel's equivalent of printf - the printk function and its derivatives. The k in printk is used to specifically remind kernel developers that the environment is different. Usage printk works more or less the same way as printf in userspace, so if you ever debugged your use
Suspend To Disk For ARM - eLinux.org
Description This page shows the result of applying suspend to disk feature for ARM architecture. Related pages are: Sw Suspend - Information about Sw Suspend Sw Suspend Porting Notes - Sw Suspend quick-hack porting guide Target Environment Hardware Information OSK reference board is used. Since OSK5912 board does not have disk to save suspend image to, flash is used to store suspend image. Softwar
Device Tree Usage - eLinux.org
Top Device Tree page (This page was previously located at htttp://devicetree.org/Device_Tree_Usage) This page walks through how to write a device tree for a new machine. It is intended to provide an overview of device tree concepts and how they are used to describe a machine. For a full technical description of device tree data format, refer to the ePAPR v1.1 specification. The ePAPR specification
Device Tree Reference - eLinux.org
Introduction Device Tree Usage If Device Tree is new to you, start with Device Tree Usage page. That page describes what Device Tree source looks like. It walks through building the source for a new machine. It describes the basic concepts, shows specific examples, and covers some advanced features. Device Tree Usage page was previously located at devicetree.org. What Is Device Tree The primary pu
Panda How to MLO & u-boot - eLinux.org
Introduction A Panda board does not have any onboard flash, where many other development or evaluation boards keep their bootloader. Rather, code onboard the board (presumably in ROM) reads the second-stage bootloaders from the MMC (SD card). The first-stage bootloader runs directly on the board from power-up. I don't know the name of this bootloader(From TI official wiki, it called Boot Rom). Thi
Mount BeagleBoard Root Filesystem over NFS via USB - eLinux.org
This page explains how to bridge the usb0 device to eth0 on your Linux host, enabling your Linux host to act as a hub for your BeagleBoard and connecting it to the outside world. As an additional reference, the following article is good at explaining how to create a typical Ethernet bridge on a Linux machine with two Ethernet cards: Linux Journal: Kernel Korner - Linux as an Ethernet Bridge Before
Android Mainlining Project - eLinux.org
This page is for organizing the Android Mainlining Project. It has information and resources associated with this project. Goal The goal of this project is to ultimately mainline all patches required to run the current released version of Android. The purpose of mainlining these patches is 3-fold: to allow a developer to use the latest released version of the Linux kernel to run an Android system,
BeagleBoardUbuntu - eLinux.org
(For BeagleBoardAngstrom, click here.) (Should Beagleboard:Ubuntu On BeagleBone Black be merged into this page?) This page is about running a Linux distribution (ARM EABI) Ubuntu on the BeagleBoard. BeagleBoard will boot the (ARM EABI) Ubuntu distribution from the SD card. Since much of this page is generic, it has also been extended to help support devices such as the PandaBoard and BeagleBone.

Android Logging System - eLinux.org
Overview The Android system has a logging facility that allows system-wide logging of information, from applications and system components. This is separate from the Linux kernel's own logging system, which is accessed using 'dmesg' or '/proc/kmsg'. However, the logging system does store messages in kernel buffers. The logging system consists of: a kernel driver and kernel buffers for storing log
Android Power Management - eLinux.org
wakelocks The first version of Android utilized a system called "wakelocks", which was a set of patches to the Linux kernel to allow a caller to prevent the system from going to low power state. Each wakelock is defined with a name and type. The type is one of: WAKE_LOCK_IDLE, or WAKE_LOCK_SUSPEND. The name is an arbitrary ASCII string. When a wake lock of type "IDLE" is in effect, the system will
Android Kernel Features - eLinux.org
Kernel features unique to Android In the course of development, Google developers made some changes to the Linux kernel. The amount of changes is not extremely large, and is on the order of changes that are customarily made to the Linux kernel by embedded developers (approximately 250 patches, with about 3 meg. of differences in 25,000 lines). The changes include a variety of large and small addit
