fix bootloader

As we know that some devices come with locked bootloaders like Sony, HUAWEI, HTC ... If you try to unlock bootloader, the data would disappear!!!Take the HTC d826y for example and our goal are to does physical acquisition so as to carve deleted data. But HTC d826y isn't on the support list of ufed or XRY and so there are nothing they can do. If you want to the root this phone, you have to unlock bootloader

The simplest bootloader steps to write:1. Initialization hardware: Close watchdog, set clock, set SDRAM, initialize NAND FLASH2. If the bootloader is larger, reposition it to SDRAM3. Read the kernel from NAND flash to SDRAM4. Set "parameters to pass to kernel"5. Jump Execution KernelImproved:1. Increase CPU frequency, 200MHZ ==> 400MHZ2. Start IcacheRelocation is divided into nor startup and NAND startint I

Briefly,Boot loader Is the firstSoftware program that runs when a computer starts. It is responsible for loadingAnd transferring control to the operating systemKernel Software (suchAs the Linux). The kernel, in turn, initializes the rest of the operating system(E.g. GNU ). I want to select bootloader for my embedded operating system and boot my most basic linux system.According to the o'reilly book I am reading, I started to select U-boot. However, du

Linux system startup process, bootloader, init system startup process take debian6 as an example 1 load BIOS hardware information and perform self-testing, and obtain boot devices (such as hard disks, optical disks, and flash memory) 2. read and execute the bootloader (such as grub) of the MBR in the startup device. 3. boot... linux system boot process, boot loader, init system boot process take debian6 as

Symptom: The PCB board will restart directly from firmware soft reset to bootloader update Problem Reason: IWDG (independent watchdog) is turned on in the firmware, no dog is fed during firmware update, causing The count is counted to 0 and the watchdog resets reset. Problem solving: 1. Since the independent watchdog cannot be turned off once it is turned on, either feed the dog in the bootloader or do

A period of time to change the STM32 of the bootloader program, but has not been tested, today put the app to write well after adding bootloader debugging together found that the app in the 0x80000000 address serial port can send and receive data, in the 0x8003400 address can only send can not receive data, compared to various registers, found that there is no configuration error, really big head. Suspect

The implementation of the boot Loader in an embedded system relies entirely on the CPU's architecture, so most boot Loader are divided into the first and second phases, which depend on the CPU architecture of the code, such as the device initial Code, etc., are usually placed in phase 1, and are usually implemented in assembly language to achieve a short and concise purpose. Phase 2 is usually implemented in C, which enables complex functions, and the code has a better Readability and portabil

First of all, bootm In the S3C2410 architecture only operates the kernel image file in the SDRAM (as if the at91 architecture provides a piece of code to copy the kernel image from flash, however, this code is not available for the S3C2410 architecture. Although you can add this code under U-boot, it seems that this code is of little use), please ensure that your kernel image is downloaded to the SDRAM, or copy the kernel image in flash to SDRAM under bootcmd. 2.
