STM32 BLUEPILL USB BOOTLOADER SUPPORT

Uploading code on to STM32 Bluepill Arduino core is through serial bootloader at USART1 or through ST LINK at SWID.
USB also can be used to upload code.
This video is on how to implement USB BOOTLOADER SUPPORT toSTM32 BLUEPILL

Flasher tool download :

Driver support :

.bin file for PC13 builtin LED board :

I am using USB to TTL converter, adjust jumper position, but Flash loader is not detecting my controller

So I need to change reaistance as shown in video?

[d.j.peters]

So you have 3 options.
1 = flash the Arduino Loader
2 = flash the STLink V2 Loader
3 = flash the Blue Pill USB Loader
The questions are what is the smallest Loader so you have more Flash memory free for your own programs ?
Thank you

my pc throws error that it does not recognise this device as soon as i connect it to my pc. i have already installed the drivers and tried many times but stuck here.

[vishnupriyatummala]

my stm is not not getting resetted it is running the same builtin code even after keeping the resistor, sir pls help me out.

sir after flashing the bootloader .then connecting the STM 32 via USB, in the device manager I cant see the com port while there is an exclamation under USB Bus controller

[tswoshman]

The link to the drivers doesn´t work man ! Where did you get the drivers from ?

[soparkarsanjay]

Can't you load boot loader using Arduino nano
There are many videos using ftdi

Hi, I have a problem with the software. When is running Flash Loader I connect the blue pill and doesn't appear any device in "Port Name", but it's recognized by W10. Any idea?

Please do a video of stm32 interfacing esp8266 using serial for wifi support
