Embedded digital video playback system software platform built-PowerPC405, embedded Linux, digital v - Business
Abstract: This paper describes the use of embedded Linux PowerPC405 on digital video playback system to build the process of software platform to explore the embedded Linux system in cross-compiler, bootloader, Linux kernel, root file system, and several other major part of the the build process. Keywords: PowerPC405; embedded Linux; digital video player; U-BOOT Introduction: Digital video playback devices in recent years developed very rapidly in a wide variety. Traditional video playback device (such as DVD player) software system is generally a simple control loop system, no operating system extensions and upgrades limited. This study is a portable digital video playback device is built on top of the embedded 32-bit PowerPC405CPU, running Linux operating system to large capacity hard disk as a storage medium, with networking capabilities. IBM, launched PowerPC405 is a specialized RISC processor for embedded applications, is widely used. Embedded Linux [1] as an open-sou rce operating system software with free of charge, to support a number of CPU, can be cut, support networks, rich software resources and so on. Use of embedded Linux to build a digital video playback system software platform allows the player low cost, easy to upgrade and manage, support multiple interfaces such as USB, enabling easy exchange of video programming and other advantages, the kind of equipment on behalf of the future development of a direction. This paper discusses the construct used in embedded digital video player Linux system bootloader, Linux kernel porting process and may be the major problems encountered, the corresponding solution. 1 digital video playback system block diagram (Chart 1-1 Stream Play System hardware block diagram) Figure 1-1 based players in the system diagram, the core control system PowerPC405-based embedded Linux, through the application process to the data storage system in the treatment program after a certain move to the stream contr ol system in the FPGA, the complete decrypted by the FPGA to give decoding system, decoding system extracted through the output RGB signal to the display device to display. Which we are concerned about is the core control system set up in embedded Linux systems. Player embedded Linux system hierarchy shown in Figure 1-2, the hardware after power, CPU's program first pointer to point to a specific memory address, the address stored with general office bootloader, bootloader initialization complete CPU and memory and other equipment, the Linux kernel in moving from the general ROM device to extract the memory and then jump to the kernel process pointer in memory of the beginning of the Department, by the Linux kernel to complete the rest of the system continue to guide the work. Re-initialize the system kernel, after completion, it loads the root file system, run user applications. The embedded Linux system platform construction process can refer to the system boot process, th e major construction work to do bootloader, Linux kernel, root file system these parts. 2 platform to build embedded Linux systems preparation (Figure 1-2 software system structure chart) To build embedded Linux platform, first of all be prepared to cross-platform development tool chain. It runs on local host, the compiler links the binary executable generated will run on the development board's CPU and operating system. Construction includes a compiler, gcc, linker ld, C library glibc toolchain, etc. There are many ways you can download the source code to the related sites compiled by hand, and the most convenient way was a good use of sound development has been compiled package, such as Germany denx company ELDK development kit, use the method, see [2]. 3bootloader and Kernel Selection Ready development tool chain, you can begin the development of embedded Linux system, first bootloader choice. 3.1bootloader choice Normal PC, after the first boot into the BIOS, the system through the BIOS for some initialization, then boot the operating system such as Windows or Linux, embedded systems in general no BIOS, but it also needs to achieve a similar function module, which is the bootloader (boot loader), its main function is to initialize the CPU, memory and other hardware devices, and into the operating system. Bootloader many different types, such as blob, lilo, grub, U-BOOT so. Currently the most widely used in embedded field is free and open source software denx's U-BOOT, it supports PowerPC, ARM, MIPS, x86 and other CPU, more than 100 kinds development board, a clear source structure, transplant easily, development rich document, users may encounter problems using general can quickly be resolved. Therefore, we use U-BOOT as a development board bootloader. According to different development boards, flash size, and model different kind of memory sizes, different ways so start making use of U-BOOT need to do some appropriate changes to meet the u ser's own development board, specific transplantation Methods and FAQs can be found in [3]. 3.2Linux kernel porting Bootloader initialization complete system hardware, put the Linux kernel from an external storage medium into memory, then, it will control to the Linux kernel, the kernel to continue to complete the system's guidance. If the kernel does not support the users to use the development board, the user needs to manually modify the Linux kernel itself to do some work related to migration, to pay attention to is on the development board's hardware peripheral parts of the deal, including the kernel basic information on the hardware board processing, on-board hardware initialization, interrupt the distribution. Development Board-level Linux kernel porting the most convenient way is to use the existing kernel and the user hardware platform closest to the development board as a template, do changes on this basis. We use the development board and IBMwalnut development boar d similar to the major peripherals, including hard drives, USB devices are using PCI bus interface adapter (PCI switch to IDE, PCI transfer USB), so the kernel of the migration work has two parts, one for the bootloader and kernel information transfer between the hardware board, two PCI peripherals for the initialization. 3.2.1U-BOOT and Linux kernel with U-BOOT complete hardware initialization after the kernel into memory,

Resolving "Make Says, Error 139" Error in Linux Computer - Computers - Data Recovery
Like other computer operating systems, Linux also indicates system problems in the form of error messages. The problems may occur at startup or while working on your system. In some error messages, the actual cause of the problem and possible solution is provided. However, some errors do not contain any suggestions. They just include some codes.
The error messages generally occur due to problems with system data structures, system files, and other resources, which make your system and data inaccessible. This behavior leads to significant data loss from your Linux hard drive and requires Data Recovery Linux to be sorted out.
In a practical scenario, you may come across the below error message while working on your Linux machine:
"Make Says, Error 139"
After the above error, Linux system does not work properly and shuts down. The problem occurs every time when you boot your system or perform a specific set of operations. This error renders your system inaccessible and causes serious data loss. In order to get your business-critical data recovered, identify the cause of this problem and perform Linux Data Recovery by resolving it.
Root of the problem
This error occurs when your compiler dumps the core. You have a damaged, old, or buggy version of the GCC (GNU Compiler Collection). The compiler corruption may occur due to numerous reasons, such as unexpected system shutdown, operating system malfunction, virus infection, file system corruption, and more.
You may also face this situations due to problems with the disk or memory corruption. The disk corruption is resulted when metadata structure of the hard drive become faulty. In such cases, operating system can not locate and access data from the hard drive.
Resolution
Go through any of the below steps to sort out this issue:
* Install latest release of Linux compiler or EGCS (Experimental/Enhanced GNU Compiler System).
* Check wait states, clock rate, and the refresh timing for SIMMS and cache. Use fsck command-line utility to scan the disk and fix errors.
* Use powerful and advanced third-party Linux Recovery software to recover lost, missing, deleted, and inaccessible data from Linux hard drive.
Linux Data Recovery tools employ high-end scanning techniques to methodically scan whole hard drive and extract all data from it. With simple user interface and read-only behavior, they perform easy and safe recovery in all cases of data loss.
Stellar Phoenix Linux Data Recovery software recovers lost data from Linux hard drive, USB drive, and network mapped drive. The software works well with all major distributions of Linux operating system, including Red Hat, SUSE, Debian, Ubuntu, and Mandriva. It supports recovery from Ext4, Ext3, Ext2, FAT32, FAT16, and FAT12 file system volumes.

Recovering File System in Linux 4 - Computers - Data Recovery
The Linux system is one of the most used operating systems in the world. It is an open source operating system that is much more secure than other operating systems. It is also very economical as it can be set up even with obsolete hardware components such as i386 or i486 processor. The Linux system also provides you the freedom to administer your system by taking care of the look & feel and also the applications that need to be installed, etc.
However, at times the Linux system gets corrupted because of various reasons such as corrupt file system, power surges, human errors, virus infections, etc. In such cases, you should take appropriate measures to overcome this issue. However, if you are unable to do so then you should use a third-party Linux data recovery software to perform Linux recovery.
Consider a scenario wherein you have a Linux 4 system, which you have restarted. But the system fails to boot and an error message is displayed, that is:
"ext2fs partition type 083..... ext3-fs: journal inode is deleted.... mount: error 22 mounting ext3 error 2 mounting name switchroot: mountfailed:22 umount/initrd/dev failed:2 kernal panic - not syncing"
Cause:The most possible cause of this error message is that the hard disk has crashed. Some bad blocks must have occurred in the inode table making the file system unrecoverable.
Resolution:To resolve this issue, you should try the following methods:
* Boot the system from the disaster recovery boot media or installation media and run e2fsk on the damaged file system.* If the data is stored on some other file system, then try to mount it and transfer the data to some other media such as pen drive or tape.
Either of the aforementioned methods may be able to either rectify the file system or transfer the data to some other safe location. However, if you are unable to do so then you should use a third-party Linux data recovery software to recover Linux file system. Such read-only tools are able to recover lost data and file systems using fast yet sophisticated scanning algorithms.
Stellar Phoenix Linux Data Recovery software is a Data Recovery Linux tool that performs data recovery of Linux file systems such as ext2, ext3, ext4, FAT12, FAT16, and FAT32. It is capable of recovering data from various hard drives such as SCSI, SATA, EIDE, and IDE. This Linux Recovery tool supports various Linux distributions such as Red Hat, SUSE, Debian, Caldera, Mandrake, Sorcerer, TurboLinux, Slackware, Gentoo etc. It is compatible with Windows 7, Vista, Server 2003, XP, and 2000.

Recovering a Red Hat Linux System After a Power Outage - Computers - Data Recovery
Today, the Linux operating system has carved a niche of its own. It has got a dedicated category of users who will happily pay for it if it ever comes with a price tag. The Linux system is secure, reliable, fast, and does not require hardware/software drivers to install them on the system. Having said that, even such a robust operating system can face corruption. Corruption can occur due to various reasons such as power outages, corrupt file system, human errors, damaged operating system, etc. In such cases, you should try performing appropriate corrective measures to sort out the issue. However, if you are unable to do so then you should use a third-party Linux data recovery software to perform Linux recovery.
Consider a scenario wherein you are working on a Red Hat Linux system. Suddenly, there is a power outage and the system shuts down unexpectedly. When you try to switch on the system, you fail to do so.
Cause:The cause of this situation is that the Linux system has corrupted because of power outage.
Resolution:If the problem is because of having a faulty hardware like bad hard drive or memory chip, the file system check may not be sufficient to resolve this problem. This happens particularly when the file system is corrupted. In such cases, the Red Hat boot process will produce an error message and guide you into a shell so that you can perform the file system repair yourself.
When the recovery shell dismounts all the file systems to mount the root file system in a read-only mode, you can perform full checks on it. To do this, you should run the e2fsck utility on the corrupted file system that will be able to resolve all the inconsistencies. Exit the shell and restart the system. The system will function normally now.
However, if you still are unable to recover the system then you should use a third-party Linux data recovery software to do the needful. Such read-only tools are able to recover the data safely without overwriting the existing data.
Stellar Phoenix Linux Data Recovery is a Linux recovery software that enables you to recover data from the corrupted Linux systems. It is supported by various Linux distributions such as Red Hat, SUSE, Debian, Caldera, Mandrake, Sorcerer, TurboLinux, Slackware, Gentoo, etc. This Linux data recovery software is able to perform Ext2 Recovery, Ext3 recovery, and Ext4 recovery. In addition, it can recover data from FAT12, FAT16, FAT32 file systems as well. This Linux recovery software is compatible with Windows 7, Vista, Server 2003, XP, and 2000.
