3D Printer MCU Firmware Transfer

@CyberSasu

Diving into the intricate world of microcontrollers, I'm Saswata, Your Trusted Embedded Systems Specialist. My skills in Arduino, C Programming, Electrical Engineering, Electronics and Microcontroller expertise make me an ideal choice for your project. To help with your firmware transfer needs, rest assured I'll leave no stone unturned. Using my knowledge in SWD/J-Link programming and IC probing, I'll try to carefully extract flash from your damaged MCU. But just in case it's impossible, I'll explore fallback options like locating the factory binary or reconstructing from the source code to get you back up and running without any compromise on functionality. Furthermore, as a meticulous professional with a passion for quality assurance, I'll ensure that the binary image in your replacement STM32H723 aligns perfectly with addresses, boot pins and security bits to guarantee a seamless transition for your board. Whether you need guidance or prefer sending me the parts for extensive support, I'm here to offer step-by-step assistance until we meet all the acceptance criteria you've set out.

The recovery of a BTT Octopus Pro V1.0.1 using the STM32H723 requires a professional sequence that goes far beyond simple file copying. Since the replacement MCU is factory-blank, it lacks the hardware configuration and the primary bootloader necessary to communicate with your peripherals. I have the verified system binaries and the specific memory mapping required to restore this board revision. Instead of risking an unstable read from the damaged original chip, I will provide a clean, production-ready software suite. This ensures that the USB-C stack and motor interfaces initialize correctly upon the first power-up. The most critical phase involves configuring the internal hardware registers via the SWD interface, specifically the nSWBOOT0 and Read Out Protection (RDP) bits. You must be extremely careful: a single incorrect click in the 'Option Bytes' menu can permanently "brick" the chip's logic. If the protection levels are set incorrectly even once, the MCU will be hardware-locked forever, making it impossible to erase or reprogram. I will lead you through the exact technical handshake to ensure these registers match factory standards, moving the board from a blank state to a fully functional controller. Ready to provide the binary package and coordinate the step-by-step restoration of your machine. Best Regards, Aleksandar Electronic Engineer BS

Hello, BIGTREETECH company and I are in the same city. I have the firmware for the BIGTREETECH BTT Octopus Pro V1.0.1 (H723) model. I can remotely guide you on how to operate it, or you can send it to me and I can help you operate it as well. I am an MTK engineer and I am in Shenzhen, China. Let me help you with it.
