Paid on delivery
Custom bootloader for STM32F412GZ to execute upon microcontroller reset. 1) When microcontroller is powered up, it should first run the bootloader 2) The bootloader should check SPI FLASH to see if there is an update available, and if so validate it, copy it to internal FLASH, and execute it. 3) If there is not an update available in SPI FLASH, the bootloader should vaildate the application program stored in internal FLASH, if image is validated, start execution of that image. 4) The bootloader should always run a validation check on internal FLASH before jumping to execution. 5) If the bootloader should fail a validation check on internal FLASH it will copy saved image from SPI FLASH to internal FLASH. 6) Would like to use online ARMmbed compiler.

Hi, I am very much interested in your project as I believe I have the expertise, knowledge, skills and tools to do your project. I am embedded software developer with more than 8 years of experience of professional embedded software development. Please take a look onto my profile to know more about me. I have quite a lot experience of STM32 processors specifically Cortex M0/M3/M4. I have written and used low level, middleware as well as higher level code. I have J-link debuggers, couple of STM32F development boards (STM32F107/F412/F446/F429/F405/F407). I have quite a lot experience with IAR, ARM GCC and Keil compilers. My recent projects that might tell you my experience and knowledge of STM32, 1. STM32F407 Discovery based CAN Data logger to log CAN data into SD Card (SDIO mode) and emulate USB MSC device to read/write SD Card data and Custom HID implementation to send/receive interrupt data. 2. STM32F412 based FATFs to read/write SD Card (both SDIO and SPI) 3. STM32F429 based FATFs to read/write USB mass storage. 4. STM32F100 based sesnor board (Reads sensor using 24bit ADC over SPI, and send reading to PC using FT232 USB chip) 5. STM32F107 based dual channel CAN to Ethernet converter. 6. STM32F407 discovery board to read via I2C BNO055 9 DOF IMU senor and save readings as CVS file using ChanFs (FATFs) in SD card in SDIO mode. I would like to know project details as what SPI flash you are using and are you going to use CRC checksum for validation? Regards, Ibrahim

Hello I have some experience with bootloader implementation for STM MCUs. I have used UART as a program source but I can modify my solution to use SPI FLASH. My solution uses only HAL libraries and my own code = no licence problem. I can deliver the solution in 7-14 days. Regard Ondrej

This shouldn't normally take long, I placed a bid assuming 2 weeks of work but, likely, it's going to be much faster. I don't have an exact STM32F412GZ the closest is the Discovery F4 board from STM that I own. It might work fine though for the development while only a final, bullet-proof testing would require the real environment. Kind regards, x3x7
