Budget: 25000 UAH Deadline: 28 days
Hello!
I have experience working with STM32, secure mode, and firmware updates. I am ready to help with the implementation of your project in Arduino IDE.
🔹 What I offer:
✅ Transitioning STM32H503CBU6 to secure mode (RDP level 2)
MCU memory protection
Ensuring UART and SPI operation after activating protection
✅ Setting up firmware updates from an encrypted file
Implementation of the OTA update mechanism
Decrypting the file before writing to flash memory
Integrity verification
📌 Work format:
✔ Arduino IDE (considering the limitations of the environment)
✔ Optimization of peripheral operation (UART, SPI) in secure mode
✔ Testing and documentation
I am ready to discuss the details and start working. How is it best to get in touch? 🚀
