Zadig driver loaded and still after the F3FC firmware update, I'm unable. The “STM32 Bootloader” shows in the device manager and lights are.

Hi Paul, I'm not sure, maybe others can help? JumJum definitely has it working on Windows 8, and I'm pretty sure I've seen it working on others too. Can you try plugging it into another USB port on your PC and just leaving it for about half an hour (with your PC connected to the net)? At least on the versions of Windows I have tried, windows takes a ridiculous amount of time to find the drivers on Windows Update. If that doesn't work, have you tried installing the XP drivers from? I know they are XP drivers, but they could potentially help (although Windows 8 should have support built in).

Also, can you try on another PC? That'd be a good way of tracking this down. Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips: • Create headers by underlining text with ==== or ---- • To *italicise* text put one asterisk each side of the word • To **bold** text put two asterisks each side of the word • Embed images by entering:![](That's the hard one: exclamation, square brackets and then the URL to the image in brackets. • * Create lists by starting lines with asterisks • 1. Create numbered lists by starting lines with a number and a dot • > Quote text by starting lines with > • Mention another user by @username • For syntax highlighting, surround the code block with three backticks: ``` Your code goes here ``` Just like, a blank line must precede a code block. • If you upload more than 5 files we will display all attachments as thumbnails.

I want to update the firmware on the board using DFU but are having some issues. I am following the instructions provided here: 2. Under item 4(d) of the document where it indicates to install the STM32 Bootloader driver, I can't find a compatible drive anywhere on the web. The windows compatibility centre search does not list any of the drivers for the STM devices I have downloaded DfuSe_Demo_V3.0.4_Setup program to do the flash but it will not work without the STM32 Bootloader driver.

Should I use a XP 32-bit driver or can someone point me to where I can download the correct driver preferably signed? Like Bizniz and Ant, I followed step-by-step instructions per 'The care and feeding of Pythons at the Redmond Zoo' but pybv10 cannot find STM32 bootloader online. Texas driver's license audit number. I manually searched but cannot find bootloader at Microsoft, STMicroelectronics nor micropython.org. My Python fell into DFU hole. My Windows7 64bit Home Premium required 124 Microsoft updates since 2014. So, I updated laptop as Ant commented. Microsoft updates require shut-downs.

After multiple restarts, no more communication at USB COM5. I manually added hardware Pyboard USB Comm Port with Wizard. COM6 installed; however, pyboard cannot start (Code 10). Auto-searched and successfully updated drivers for other hardware. Red, yellow, blue LEDs are light on pyb10. Pyboard cannot crawl out of missing bootloader?

Only pyboard & my first using microcontroller, help. After hours of trials, my Python climbed out of bootloader DFU hole. I uninstalled COM6 port. Revert to original USB port COM5 for MicroPython driver 5.1.2600.3, manually set COM5 speed to 115200 bps to match. Pybv10 then finally able to auto search online and find the bootloader ST Tub30sys driver v.3.0.4.0 written 5Jul2012 by STM.
