As an example, to compile for a Bluepill board with 128 KiB flash, use: The high memory bootloader is a variation that doesn't require the application to be at an offset, the bootloader resides in the top 7 KiB of ROM and hides its reset and stack vectors inside unused entries of the application vector table. High memory bootloader for 256 KiB chips (experimental) High memory bootloader for 128 KiB chips (experimental) High memory bootloader for 64 KiB chips (experimental) Standard bootloader, using first 8 KiB of flash

Once the bootloader is installed, you can simply upload any code to STM32 Board directly using mini USB Cable.LeafLabs Maple Mini board and clone derivativesīigTreeTech SKR MINI E3 V2.0 (3D printer motherboard)įor the above targets there are some potential variants that can be added to the target name based on what the target supports: Target Variant Watch the full video tutorial below to learn about how to upload bootloader to STM32 using USB-TTL Converter.

All the components can be purchased from Amazon. The following are the components required for STM32 Bootloader Programming via USB.

This boot loader can be flashed into the STM32 once and thereafter we can directly use the USB port of the STM32 board to upload programs just like any other Arduino boards. But there exists a boot loader program developed by LeafLabs for Maple mini boards. Hence the board will not be discovered by your computer when connected through the USB. The reason for doing that is, when the STM32 development board is bought it does not come with an Arduino ready boot loader. Also, the mini-USB port on the Development board was left totally unused. We also had to toggle the boot 0 jumpers to boot 1 position while uploading and testing code. We utilized an FTDI programmer/ USB-TTL Converter module for programming. But there was one huge drawback with it because of the method we used to upload the code. We also programmed the STM32 development board to blink an LED. In our previous tutorial, we learned the basics of the STM32 Development Board. Programming STM32F103C8 Board using USB Port The previous tutorial link: Getting Started with STM32 Microcontroller : Blinking of LED STM32 Development Board or STM32F103C8 Microcontroller can be easily programmed using the Arduino IDE, only after installing the bootloader. This post is all about installing STM32 Bootloader, i.e Programming STM32F103C8 Board using micro USB Port directly via Arduino IDE.
