10. efore the operating system starts running In our case the bootloader is the code that runs before the device firmware starts up Typically a bootloader is used because the system memory is too small to contain the entire program and so the bootloader uses a set of routines to call the program from a different part of memory The CoiNel LPC2148 ARM7 USB Boot loader performs three steps 1 First the Boot loader checks to see if a USB cable has been plugged in If the LPC2148 is connected as a USB device 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 2 The next thing the Boot loader does is look for a firmware file This file contains the desired operating firmware in a binary file format for the LPC2148 If the Boot loader finds this file system then it programs the contents of this file to the flash memory of the LPC2148 In this way the Boot loader acts as a programmer and we can upgrade the firmware on the LPC2148 simply by loading a new file 3 After performing for first two checks the boot loader calls the main firmware www coineltech com 3 CoiNel Technology Solutions LLP ll Why would you use the LPC2148 USB Bootloader The bootloader provides several distinct advantages First if you have a LPC2148 Board that has been preloaded with the bootloader then you don

12. t even need a programmer to load code onto the board Another reason that LPC2148 USB Boot loader is great because it is very fast at loading code When using a serial programmer to load code onto an ARM it can take several minutes to get your code up This can be a major setback when you re writing very large programs and you start debugging Using the LPC2148 USB bootloader allows you to load code in seconds lll How do you use the Boot loader First you have to program the Boot loader code onto the LPC2148 Board The Boot loader code can be downloaded at the download section of LPC2148 Based product page You can check the product page at www coineltech com shop You may either use FLASH MAGIC software for programming i e serial programming or H JTAG parallel port programming to load this code Once the Boot loader program is on the LPC2148 using it is very simple Let us assume that you have written some neat code to use on LPC2148 Board Plug in a USB cable and when the USB Mass Storage Device opens on your desktop just drag and drop the binary file onto the device then press reset the bootloader will look for the binary file and if the file is found the bootloader will program the new code onto the controller That seems easy enough but how do get this binary file In order to get the binary file first we have to compile the code In order to compile the code you need have Kiel uVision4 Below steps would show you how to creat
