-Oxford Boot Loader is developed by Darron M Broad with contributions from Gerhard Bertelsmann.+Oxford Boot Loader has been developed by Darron M Broad and is a port of [[:projects:wellington|Wellington]] boot loader developed by Darron M Broad with contributions from Gerhard Bertelsmann.
  
 I am grateful to Chiculita Claudiu for Tiny PIC Bootloader as Oxford Boot Loader uses a protocol derived from Tiny PIC bootloader. I am grateful to Chiculita Claudiu for Tiny PIC Bootloader as Oxford Boot Loader uses a protocol derived from Tiny PIC bootloader.
  
 +=== Checkout ===
 +
 +Oxford boot loader is obtained using mercurial.
 +
 +<code>
 +hg clone http://hg.kewl.org/pub/oxford
 +cd oxford
 +</code>
 +
 +=== Configure ===
 +
 +Configuring Oxford is a simple case of copying two template files for
 +the target device and editing it to suit the target application.
 +
 +The first file is the assembly code for the loader and the second file
 +a GNU make file for building the loader.
 +
 +<code>
 +cd boot
 +cp template.mk mk/myproject.mk
 +cp template.s myproject.s
 +vi myproject.s
 +vi mk/myproject.mk
 +</code>
 +
 +Follow the guide given in the template files to create the correct boot loader
 +firmware for your target then build the boot loader. [[:tools:xc16|XC16]] must
 +be installed to perform this operation.
 +
 +<code>
 +make
 +</code>
 +
 +=== Program ===
 +
 +Now you must program the boot loader onto the target device. This will depend
 +on the programming tool you have available and in this example we use
 +[[:projects:pickle|Pickle Microchip PIC ICSP]].
 +
 +<code>
 +p24 select dsPIC33EP128GP502 lvp program myproject.hex
 +</code>
 +
 +Once the boot loader hex file is on the target it may be reset whereupon
 +it will listen for a connection from `easy-loader' already installed on
 +the host platform.
 +
 +=== Upload ===
 +
 +In this final step you now take the application for your target device
 +and upload it to the boot loader which will store it in flash memory.
 +
 +This process is documented on the [[:projects:easyloader:|Easy-loader]] page.
