In this project, I have designed HTTPS server application on STM32H7 to serve some html pages using mbedTLS on top of LwIP stack. I have also developed bootloader firmware to boot from USB mass storage device or QSPI flash with FAT file system, load firmware image into RAM and executing code from there.
