Bootloader needed for PIC32MX250F128B

Need a bootloader for PIC32MX250F128B chip. We have app developed but need the ability to reload software under a variety of conditions. Boot loader should trigger when flags are set at a static memory location. Bootloader should also trigger if a USB thumb drive is connected that has a predefined file name present in the root directory. Application will set flags to initiate trigger under the following conditions: 1. User chooses to update software, this will be done through web interfact that is not part of this project. This web interface will set one of the flags as previously described. [login to view URL] Timer triggers a number of times sequentially without resets. This would mean that the application has been corrupted and needs to be refreshed. The watchdog timer app will set one of the flags mentioned above so this code is not part of the project. Developer must deliver working tested code. You may use a dummy main program with a simple loop for testing. We will then substitue our applicaton code in the main progam. Code must follow best practices conventions for C embedded code. Code must be well documented. Do not apply for this project unless you have done this before, we will need to see example code first. this should not be a difficult or time consuming task for someone who has done this before and understands the process exactly. If you disagree don't apply please.
