Stm32 Bootloader Driver On Windows

While it supports USB, it requires a special driver on Windows.

Do this by running the application: VCPV1.5.0Setup.exe where corresponds with your machine OS and architecture.

Make sure that Windows detects a valid COM port, the device should appear as STMicroelectronics Virtual COM Port (COMx) in the Device manager.

If you see a yellow exclamation mark it means that your driver is not properly installed.

In case there is an issue installing the driver, try the following steps.

I always get the following results no matter when I click the reset button: Sketch uses 17168 bytes (26) of program storage space.

I have periods where the upload works 99 fine, and periods where I have to press reset during upload all the time (with a correct USB clock).

Still thinking what could be the cause for such changes in the DFU mood.

While I have not been on Windows in a year, my very well tuned Win8.1 box used to fail perhaps 4 or 5 time per 100 (guess I did not count every failure.) Just when you though everything was perfect poof, an upload FU.

If you must have 100 upload reliability, you are using the wrong technology.

While Linux hosting is better IMO than Windows 810, it is still not perfect; an occasional hiccup will happen.

This hack, breaches the USB spec, so is not guaranteed to work.

I use all sorts of MCUs for work, and find even expensive commercial SWD programmers sometimes fail to upload, and I am forced to powercycle the MCU, and try again.

ISSUE: I have a similar problem with the Blue Pill bootloader running on Windows 10 x64.

I downloaded the genericboot20pc13.bin per the instructions at bootloader.

Before loading the first sketch, the Blue Pill shows up in the Device Manager as Atmel USB Device Maple DFU device.

But the Arduino v1.8.3 IDE expectsrequires the Blue Pill to be a virtual COM port device to download a sketch (i.e.

Ports(COM LPT) COMx under the Device Manage).

In searching the web I found a suggestion to push reset button after the sketch has compiled and before the download starts.

With luck one can push the reset button at the right time during the Arduino compiledownload process to make this work.

Then, once one has successfully downloaded their first sketch, the Blue Pill shows up in as a Ports(COM LPT) COMx device.

This allows the Arduino IDE to properly download any subsequent sketch.

The problem seems to be that on reset the bootloader expects a sketch to be present before it forces the re-enumeration to switch from being a Maple DFU device to a virtual COM device, which is what the Arduino IDE expectsrequires for downloading a sketch.

SUGGESTION: Eliminate this initial sketch download issueproblem by Including a dummy sketch (e.g.

LED) as part of the bootloader download process.

Thus on reset the bootloader will always find a sketch to run and will always force a re-enumeration to switch from being a Maple DFU device to a virtual COM device.

I would bet that the hack doesnt work anymore like it used to.

If the COM port is busy, the magic sequence cannot be sent, hence no reset.

I think I posted somewhere in the forum how to solve this, so you better search for it.

I downloaded the genericboot20pc13.bin from the latest Github Latest commit e851e8a 6 days ago and downloaded it to my Blue Pill STM32F103C8 board.

The board shows up in the Device Manager using Show hidden devices as hidden: Other devices Maple 003 (both with ) and non-hidden Ports (COM LPT) USB Serial Device (COM4).

Im trying to download the the File Examples 01.Basic Blink Sketch, and my setup is Tools Board: Blue Pill F103C8, Upload method: STM32duino bootloader, Port: COM4.
