Programming STM32 (Blue Pill) Directly Through USB Port

Just use the micro-USB port on the STM32 board to connect it to the computer as shown below. Make sure the jumper 0 pin is positioned back at 0 (Operating mode). Hereafter we need not toggle the jumper anymore to upload and run the programs.

How do I program my USB STM32?

The first step is to connect the STM32 Blue Pill board to the USB to Serial Adapter as shown in the image above. Also, the BOOT0 pins made HIGH i.e. the board is put in Programming Mode. Once this is done, you can connect the USB to Serial Converter to the PC and check for the COM Port.

Does STM32 come with bootloader?

System bootloader in STM32 is the bootloader that has been provided by the chip manufacturers. That we cannot overwrite as it has loaded into the ROM memory. We can also call this as a ROM bootloader. Using this bootloader, we can update the firmware or application from the bootloader.

What is USB bootloader?

A bootloader is a small piece of code that runs before the operating system starts running. In our case the bootloader is the code that runs before the device firmware starts up. ... First, the bootloader checks to see if a USB cable has been plugged in.

How do I upload to STM32?

Create a LED blink sketch. Set the STM32 Blue Pill to bootloader mode using both BOOT0 and NRST button. Click on the upload button to compile and upload the code to STM32 Blue Pill. Once the sketch is successfully uploaded, the blue LED should blink at 0.1 second interval.

What is DFU mode STM32?

DFU or DfuSe is the USB package for do a firmware upgrade on STM32 via USB. DfuSe contains the demo GUI, debugging GUI, all sources files and the protocol layer. ... The ability to program an "empty" STM32 device in a newly-assembled board via USB. And easy upgrade the STM32 firmware during development or pre-production.

What is USB TTL?

The USB TTL Serial cables are a range of USB to serial converter cables which provide connectivity between USB and serial UART interfaces. A range of cables are available offering connectivity at 5V, 3.3V or user specified signal levels with various connector interfaces.

How do I reflash STM32?

Plug the ST-LINK or evaluation board with embedded ST-LINK into the USB port of the PC. In the STM32 ST-LINK Utility window, click the Connect icon on the top toolbar (or Target → Connect). Use the Open File icon on the top toolbar (or File → Open file...) to open the binary file to load to the STM32.

What is STM32 boot pin?

Most of STM32 familly have BOOT0 pin and recent device have both BOOT0 pin and BOOTn user option bytes. Check the reference manual of your device. By default, if your firmware is programmed in FLASH (when using SWD) BOOT0 = GND. If BOOT0 = VDD you can enter in bootloader mode or relocate your code in SRAM.
