Firmware updater -- bootloader on Microchip PIC

Title: Bootloader for 18F4620 microprocessor Equipment: Etherstuff ET-1 hardware ??" PIC18F4620 microprocessor, RTL8019AS Ethernet interface, RJ-45 connector with magnetics, 24LC256 or 24LC512 IIC eeprom. Compiler: CCS PIC-C Details: Create small flash "boot-loader" application on a PIC 18F4620 using existing TCP/IP stack which will allow for loading application firmware (via an existing UDP-based protocol) onto the PIC over Ethernet connectivity. The new uploaded code will be stored temporarily in an on-board EEPROM. The uploaded code should be encrypted in some simple manner before sending. After the code is validated on the chip (for missing segments, errors, and encryption signature), it must be decrypted and copied into place on the device. The Windows-based UDP uploader already exists (MSVC), but will need some minor modifications to support this new functionality. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition. All code must compile without warnings. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform PIC18F4620 microprocessor 24LC256 or 24LC512 IIC eeprom Compiler: CCS PIC-C ([login to view URL])
