Write a specialized C firmware bootloader for a Microchip microcontroller

Hi, I am a post graduate power electronics engineer and having very good experience in product design and development. I am excellent in embedded design & programming using pic, dspic controllers and MATLAB codding for Power projects, Boot loaders, Bluetooth & GPS designs, CAN communication, EEprom. UART , RF circuits ,Protocols for networking, wi-Fi routers,OBD diagnosis with CAN bus protocols, Electrical vehicles and AC drives, stepper motor controls. I designed sine wave inverters for standalone and grid tie Inverters. I designed projects like Off line UPS up to 3 KVA, 5kW motor controller for electrical vehicles ,synchronous rectifiers, Solar MPPT chargers, Solar trackers, Battery chargers ,Grid tie inverters design with PLL and feedback control circuit emergency light of 66W and Online UPS control cards, Battery Charging power supplies, LED drivers for PWM controlling and dimming, SMPS, Power supplies. I have experience in schematics and PCB design experience in Altium and ORCAD. I am ready to work for you. Please contact for further discussion.

Hi Sir, We are expert in embedded C programming, We can develop you this bootloader. We offers you our services and we assure you quality of work. Lets talk to us on this project. thanks. Regards, Ahmed

Good day, I have experience developing custom bootloaders for embedded devices. Please check my profile for reviews and client feedback on previous feedback work. I will develop the main bootloader in C and the host application in python.

Hello i am experienced C/C++ developer for various embedded and linux. Important note: You can't reach goal of this project with algorithms you provide in the document. Will try to explain: when you change firmware a bit and some function change its binary size (grow or shrink) many other functions change its place (offset) in the binary too. so bootloader will download almost all firmware in a less efficient way in comparison to dumb bootloaders. Solution here is to implement binary diff algorithm but i am not sure if it can be effectively implemented in this case (bootloader have access only to one binary data). I propose to develop such algorithm for you and imlement it for Microchip & Node.js as you requested. --- Update 29 sep: As we talk through chat i update my proposal, (see updated milestones). Sorry for delay. You should send me pic24FJ1024GB606 board, meanwile i will start implement parts not dedicated to board itself (algorithm, protocol, server). Thanks.

basics project could be done in 3 days, We can start from at least $ 250, updates every 3 days We can discuss for discounts scheduled payment by 12 months or 6 months 15+ years in Technology Business and Manufacturing ( engineering Science) You have my Warranty and conditions limited support plan for 1 year

Hello, i have read the details provided..please contact me to discuss more on the project deadline and some other few things

Hello Sir, I am embedded software developer and and worked on several industrial projects. I have written bootloader for stm32 as well. I have good experience on such technology and pretty confident that i can deliver this project as per your expectation. Let me know what you think about my proposal. Thanks

Hello, my name is Felipe and I have a MsC in Mechatronics Engineering with specialization is embedded systems, electronics and control. I work in a multinational company and, here at my work, I got the chance to develop a bootloader for a Renesas RL78 microcontroller. The bootloader's main goal was to flash encrypted software through UART, where the decryption was made inside the bootloader. Using my past experience, I think I could develop the bootloader with quality and robustness. I think 30 days to deliver the solution is a fair time, specially because of the solution's complexity. Within this time, I can deliver the bootloader firmware, NodeJS App and documentation for the developed code.

I am familiar with the Microchip 24FJ family of chips and bootloaders for Microchip products. These chips are used in products I coded for Orycon's hot runnerless mold equipment. See www.orycon.com. Microchip XC16 version of C was used. Can I assume you want the bootloader to read a standard HEX file and not necessarily a plain image file? Can I also assume the bootloader is part of the main code and will be coded in both the active and inactive partitions? I'm sure we can use some standard off-the-shelf NodeJS product to transfer the file. Langston
