Hello, I have existing code and would like to add the ability to update the firmware from the running code. So I need a couple of functions. One function that receives the hex code and stores it in memory buffer. Another function to take the memory buffer and store it to the eeprom. We can pass in the CRC and size to ensure there is no corruption, if the file fails we simply return false. This will be for the stm32f4 microcontroller and should work on the stm32f4 discovery board. something like this Structure update update len update crc void initUpdate(update) // allocate memory buffer // store len and crc bool addNextByte(byte) // stores next byte to memory // on last byte verify crc bool applyUpdate() // takes buffer and writes to eeprom Code should be able to compile and run on a discovery board. You will also have to create an application to pass the hex file through one of the uart ports for the update. This application can be in c or in python. I will test on a discovery board with a few updates. I have all the required hardware.

Hi! I have experience solving a similar task but with an another microcontroller, certainly with a device from Xmega MCU family from Atmel. But I'm familiar with principles of firmware update from a running one. And also in creating a downloader application for PC, running different OS (Linux, Windows)
