Bootloader Generator User's Guide Bootloader Generator User’s Guide 2015-2016 Microchip Technology Inc. DS40001779B Note the following details of the code protection feature on Microchip devices: • Microchip products meet the specification contained in their particular Microchip Data Sheet. • Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. • There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. • Microchip is willing to work with the customer who is concerned about the integrity of their code. • Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.” Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act.

  • Project Log 2 2 LPC2148 USB Bootloader
    Project Log 2 Project Title: USB MicroSD Card Reader EEE G512 Embedded System Design October 2018 Submitted by: Submitted to: Joy Parikh j 2016A3PS0136P Dr. Devesh Samaiya Rutwik Narendra Jain j 2015A3PS0726P 2 LPC2148 USB Bootloader The LPC2148 USB bootloader performs three steps: 1. The bootloader checks to see if a USB cable has been plugged in. If the LPC2148 detects the presence of a USB cable then it initiates a USB Mass Storage system. This will cause the target board to appear on any computer platform as a removable flash drive. The user can then seamlessly transfer files to the flash drive. In the background, the LPC2148 moves the user's files onto the SD card using the FAT16 file system. 2. The next thing the bootloader does is look for a firmware file (a file named FW.SFE). This file contains the desired operating firmware (in a binary file format) for the LPC2148 mi- croprocessor. If the bootloader finds this file on the FAT16 system then it programs the contents of this file to the flash memory of the LPC2148. In this way, the bootloader acts as a \programmer" for the LPC2148; and we can upgrade the firmware on the LPC2148 simply by loading a new file onto the micro SD card. 3. After performing the first two checks, the bootloader calls the main firmware. The main code should not even know that the bootloader was used and will run normally. 2.1 Details The USB device class used is MSCD (Mass Storage Class Device). The MSCD presents easy integration with PC's operating systems.

Rev. 1.7 UG103.6: Bootloader Fundamentals Introduction 1. Introduction The bootloader is a program stored in reserved flash memory that can initialize a device, update firmware images, and possibly perform some integrity checks. Firmware image update occurs on demand, either by serial communication or over the air. Production-level pro- gramming is typically done during the product manufacturing process yet it is desirable to be able to reprogram the system after produc- tion is complete. More importantly, it is valuable to be able to update the device's firmware with new features and bug fixes after deploy- ment. The firmware image update capability makes that possible.

For example, application note AN3561, "USB Bootloader for the MC9S08JM60," describes a USB bootloader that was written for the Flexis JM family. The MSD bootloader described in this application note is offered as another option, and has these advantages: • It does not require a driver to be installed on the host. • It does not require an application to run on the host. • Any user can use it with a little training. The only action required is to copy a file onto a drive. • It can be used with many different host operating systems since it requires no host software or driver This bootloader was specifically written for several families of Freescale microcontrollers that share similar USB peripherals. These families include, but are not limited to, the following: • Flexis JM family MCF51JM © 2011 Freescale Semiconductor, Inc.

  • Bootloader and Startup Feature Overview and Configuratoin Guide
    TechnicalTTechnicalechnical GuideGuidGuidee Bootloader and Startup Feature Overview and Configuration Guide The AlliedWare Plus™ Bootloader Every switch has a startup process. The end result of the startup is that the unit is running a specific version of the operating system software, with the features configured according to a specific startup configuration file. The startup process goes through two main phases: First, the switch boots up off a dedicated bootloader software image, which initializes core functionality of the unit. Then, the bootloader launches the main operating software image, and passes control over to this operating system. The bootloader is the executable code responsible for setting up the system and loading the operating system software. The bootloader is the software that runs the unit when it first powers up, performing basic initialization and executing the product software release. As part of the startup process of the switch, the bootloader allows you various options before running the product operating system software.

  • MSP430™ Flash Devices Bootloader (BSL) User's Guide (Rev
    www.ti.com Table of Contents User’s Guide MSP430™ Flash Devices Bootloader (BSL) ABSTRACT The MSP430™ bootloader (BSL) (formerly known as the bootstrap loader) allows users to communicate with embedded memory in the MSP430 microcontroller (MCU) during the prototyping phase, final production, and in service. Both the programmable memory (flash memory) and the data memory (RAM) can be modified as required. Do not confuse the bootloader with the bootstrap loader programs found in some digital signal processors (DSPs) that automatically load program code (and data) from external memory to the internal memory of the DSP. To use the bootloader, a specific BSL entry sequence must be applied. An added sequence of commands initiates the desired function. A bootloading session can be exited by continuing operation at a defined user program address or by the reset condition. If the device is secured by disabling JTAG, it is still possible to use the BSL. Access to the MSP430 MCU memory through the BSL is protected against misuse by the BSL password. The BSL password is equal to the content of the interrupt vector table on the device.

  • UEFI, Booting & Partition Management
    UEFI, Booting & Partition Management Kelvin Cording July 2018 Unified Extendible Interface (UEFI) • Modern computer and Windows are moving away from the traditional MBR based boot- up processes to hardware and software using UEFI • Win 8 introduced UEFI • If Windows 8 is already installed using Legacy BIOS, it can't be converted to UEFI. A new OS installation is required. Understanding a computer boot up process When you hit the power button of your PC, an execution begins that will eventually load the Operating System into memory. This first execution depends on the partition structure of your hard disk. We have two types of partition structures (or formats): MBR and GPT. The partition structure on a drive defines three things: • The structure of data on the drive. • The code used during startup if a partition is bootable. • Where a partition begins and ends. MBR -Master Boot Record GPT Globally Unique Identifier Partition Table = GUID Partition A comparison of GPT and MBR partition structures A comparison of GPT and MBR partition structures (2) Max partition size in MBR is ~2TB whereas in UEFI it is ~9 ZetaBytes One zettabyte (1021) is approximately equal to a thousand exabytes or a billion terabytes. MBR can have at max 4 primary partition whereas GPT can have 128. MBR can store only one bootloader whereas GPT has a separate dedicated EFI System Partition(ESP) for storing multiple bootloaders. The MBR Boot Process Before the BIOS can detect the boot device, it goes through a sequence of system configuration functions starting with: • Power-on-self-test. • Detecting and initializing the video card.
