I am not exactly sure how they uploaded the code to the STM32. However, I do have an idea on how they do it. As you can tell the files are .ino files which means they are Arduino files. There is a project called stm32duino which provides support for controlling STM32 using Arduino APIs.
I tried it on STM32 Nucleo L476RG and it worked. However, not sure if it will work of the STM32 used in the AMD-R. You might need to flash the bios for it to work. A guide on using the STM32duino can be found on their wiki. Might also consider updating a README for this. On the bright side, I saw it in one of the supported board
