Job Description: We are seeking a highly skilled RTOS Embedded Systems Engineer to design and implement an Over-The-Air (OTA) firmware update mechanism for our STM32-based IoT device. Our device uses a SIMCOM 7070G module for internet connectivity and communicates with AWS IoT Core over MQTT. The device also reads sensor data and sends it to a separate server over MQTT. Responsibilities: Design and develop a secure and efficient bootloader for the STM32L151CCT6 microcontroller, which will reside in a separate partition in the flash memory. Create three separate sections within the device's flash memory: one for the bootloader, one for the currently running application firmware, and one for incoming firmware updates. Implement a mechanism in the bootloader to verify the integrity of the new firmware before applying the update, such as a checksum or CRC. Develop an OTA update mechanism that can receive and store incoming firmware updates (received via MQTT from AWS IoT Core) in the dedicated update partition of the flash memory, without disturbing the current firmware. Ensure the bootloader applies the new firmware (from the dedicated update partition) only after successful integrity check. Design a fail-safe firmware update process: if the update fails or if the new firmware is faulty, the bootloader should revert to the previous firmware. Implement an RTOS for efficient task management and to meet real-time requirements. Develop software to read sensor data and transmit it to a separate server over MQTT. Provide comprehensive documentation detailing the design, development, and implementation of the bootloader, OTA firmware update mechanism, and RTOS use.

As you may be aware, we are seeking a highly skilled Embedded Systems Engineer to design and implement an Over-The-Air (OTA) firmware update mechanism for our STM32-based IoT device. We have already developed a secure and efficient bootloader for the STM32L151CCT6 microcontroller, which will reside in a separate partition in the flash memory. Three sections within the device's flash memory will be used to store the currently running application firmware, incoming firmware updates received via MQTT from AWS IoT Core, as well as the bootloader. The RTOS used in our system will have three main functions: efficient task management to meet real-time requirements; integrity verification of new firmware before applying the update; and fail-safe mechanism for reverting to previous firmware if the update fails or if the new firmware is faulty. All code will be written in accordance with industry standards such as ISO 26262 and UEFI SecureBoot to ensure security and reliability. Additionally, full documentation detailing the design, development, and implementation of the system will be provided along with periodic updates as required.

Fortunately, I must say that my last project was the implementation of OTA on silicon lab microcontrollers (EFR32), and I completely understand your needs in this project. I hope we can cooperate because this project is an interesting challenge for me and it will be registered here as my first project. Best regard Iman Mirzajani

If you choose to consider making this project with the esp32 -- I can help you do this pretty fast. I have been all through the AWS IOT Core tools set and have done all the OTA work already. The AWS Jobs console handles everything you would want to accomplish for monitoring and controlling your update. The ESP-IDF has all the fail-safe, roll-back OTA mechanisms that you need built into the software library.

Dear Client, I am confident that my expertise in embedded systems, firmware development, and OTA updates align perfectly with the requirements of your project. Here is a breakdown of my proposed approach to addressing the responsibilities outlined in your job description: Bootloader Design and Development: I will design a secure and efficient bootloader for the STM32L151CCT6 microcontroller, which will reside in a separate partition in the flash memory. Flash Memory Organization: I will create three separate sections within the device's flash memory: one for the bootloader, one for the currently running application firmware, and one for incoming firmware updates. OTA Firmware Update Mechanism: I will develop an OTA update mechanism that can receive and store firmware updates in the dedicated update partition without disturbing the current firmware. Fail-Safe Firmware Update Process: I will design a fail-safe mechanism within the bootloader that allows it to revert to the previous firmware if the update fails or if the new firmware is faulty. RTOS Implementation: I will implement an RTOS to efficiently manage tasks and meet real-time requirements. Sensor Data Transmission: I will develop software to read sensor data and transmit it to a separate server over MQTT, ensuring reliable and efficient communication. Best regards, Nikita.
