Re: Blue pill shows up as "Unrecognized device" even after installing drivers...

Look in https://github.com/rogerclarkmelbourne/Arduino_STM32/tree/master/tools/win there is stm32flash.exe Got it, thanks. I forget the exact syntax but the uploader uses stm32flash -g 0x8000000 -b 115200 -w %str% %1 I suspect %str% %1% is the file to write to the board To be precise, %str% is the ...

Re: Blue pill shows up as "Unrecognized device" even after installing drivers...

It normally takes a few seconds to flash the bootloader (as it now includes a dummy sketch and its 28 in total I think) You could try reading back the flash, if the python tool supports that. Mmmh, it looked shorter than that. I'll see what I can find... PS. Why are you using Python ? there is a bi...

Re: Blue pill shows up as "Unrecognized device" even after installing drivers...

Hi, Roger, I've heard of some boards where the flash is locked. Perhaps in this case the python flasher is not able to unlock However its strange that you get some flashes. Apart from trying on a Windows machine using ST's own tools... Well, ST's tool can seemingly flash through serial indeed, but s...

Re: Blue pill shows up as "Unrecognized device" even after installing drivers...

Hi, OK, here's a report of the tests I made this evening: 1) I resoldered the USB connector on the first board (damn, those traces are thin), checked continuity and checked there was no short. It didn't change anything (but I admit I had little hope as there was no 6 quick flashes anyway). 2) I unpa...

Re: Blue pill shows up as "Unrecognized device" even after installing drivers...

Sounds like faulty usb connections Its not uncommon for dry joints on the USB connector I would have expected no detection at all in this case, but maybe if only D+ ou D- is affected it could be a "half usb" and cause the observed symptoms. I'll resolder the connector tonight along with preparing t...

Re: Blue pill shows up as "Unrecognized device" even after installing drivers...

I flashed the latest bootloader into my new BPill (it flashes 6x fast and 6x slower upon reset). Replaced the 10k resistor with 2k2 one. Win7 64b. Rogers repo. 1. When I upload my sketch (I have to press reset button) it uploads fine, and switches to COM25. I see COM25 in the DevMan. I can see my d...

Re: Blue pill shows up as "Unrecognized device" even after installing drivers...

HI all, and thanks for all your replies. The latest bootloader includes a dummy sketch, so after it switches from bootloader to sketch it should show up as serial. When you plug the board in, the LED should flash very quickly 6 times followed by 6 flash (but not as fast) flashes This indicates the b...

Blue pill shows up as "Unrecognized device" even after installing drivers...

Hi, I'm pretty sure I'm missing an important step but I really can't figure out which one, so after a full day of research, I decided to post here, even if I look like a newbie - which I am regarding STM32 btw :-). Hardware : "Blue Pill" from Aliexpress . OS1 : Windows 10 64bit French OS2 : Windows ...

Hi, STM32 newbie here

Hi, I'm a software engineer with a background in electronics. I have some experience with Arduino and ESP8266 (a few projects are documented on my blog ) and thought of giving a try at the blue pill, mainly because of its speed and high number of I/Os. My first experience is frustrating, with a Wind...
