How to Install the STM32 USB Bootloader, New Version! (Blue Pill F103C8T6)

[@frackingoil322]

After a full day of trying to get my ST32 to work, you came in clutch. Thank you so much!

[@UndefinedEssence]

This is one of the best videos for this, I appreciate the clean look and sound of the video as well.

[@CalebMarting]

Thank you! Glad you enjoyed

[@batuhansarp683]

Agreed, if windows doesn't recognize the bluepill just unplug it from power and plug it again several times, it will work.

[@n0m1c]

I had tossed 5 blue pill boards in a drawer after wrestling for days to get them to work with Platform.io back in 2018. I recently got interested in using them with DIY Eurorack synth modules. This procedure & the new bootloader did the trick, even with counterfeit CKS32F103C8T6 microcontrollers on the boards! Thanks for the update!

[@CalebMarting]

Thank you! I have a couple of CKS ones as well and they worked fine as well with this. I wonder what doesn't work though lol

[@luizdanielsantos]

Use the PB2 port tied to +3.3V after a RESET. This will kick in the HID Bootloader (even with anything written previously). One also can unplug the USB, tie PB2 to +3.3V, and plug it to the USB port, this also can kick in the HID Bootloader.

[@walterhynson2898]

wow ,looks like the folks over at STM finally got it together and realized Arduino is here to stay. THANKS

[@ok4rm]

Very useful video, thank you. I solved my bootloader problems with two different STM32 boards within a couple of minutes. Especially the links in description are very useful: all are valid and get the right things I needed. Perfect explanation why and how. Many, many thanks!

[@raimondfoekema6263]

I also solved my bootloader problem but what i found out later is that the usb comminication gives trouble with my serial3 connection to my blue tooth module, every time it looses connection with the pc and i have to upload the bootloader again. Do you experiance the same?

[@dave_dennis]

How ironic that you uploaded this UPDATE on the very day I was researching how to do this. Thanks for making an UPDATE!

[@CalebMarting]

No worries, happy I could help. This UPDATE'S bootloader is a lot more user friendly than my other videos bootloader so it needed to be done. Have fun!

[@ihakov]

Thank you very much for your guidance. Spent 1.5 days to make STA32 working until I saw your video. Now I am good now. Just FYI, I used STM Flash Loader to flash bootloader and in the Arduino's Upload method I used HID Bootloader 2.2

Glad it helped!

[@OmarElmasry1]

this video is amazing on so many levels , liked and subbed.

[@smilespray]

Thanks for this! I already had a pile of these lying around, but I haven't used them due to programming being fiddly. Ordered 10 more and will be flashing the new bootloader on all of them.

[@CalebMarting]

Sounds awesome! I am amazed at how well this bootloader works so happy to spread the news. Best of luck!

[@davidwoodward7003]

Great video! Explained a lot of the basics that other videos skipped over.

[@dentakuweb]

Nice! I was able to program my Blue Pill a while ago then something happened and I just kept getting errors. This video inspired me to clean up my IDE and set everything up again. By following your instructions I was able to get it all working again. Now I need to see if I can program a little 32F030F4P6 board I got a while ago.

[@CalebMarting]

Good luck! Glad it worked

[@dentakuweb]

@@CalebMarting Last night I opened up Serial Monitor WHILE uploading a sketch and the Bluepill could no longer be recognized as a usable USB device on ANY computer so I went through the process in this video again and now it works.

[@CalebMarting]

It's possible that something got messed up, or a setting wasnt set correctly. apparently you can set the boot and one jumper to the one position and that should force the bootloader to start when you press reset. Then you can see if the USB device is recognized

[@dentakuweb]

@@CalebMarting OK. If it happens again I'll set both jumpers and reset to see if it works. Re-flashing the bootloader isn't difficult anyway.

[@Egon_Freeman]

So what should I do if, with BOOT0 in 0, connecting the USB to the PC nets me a "USB device not recognized"? Unplugging and plugging back in however many times _doesn't solve the issue._ I programmed the bootloader with "Verify programming" and it verified. I can also upload the blinker via Serial and it seems to work fine... I supposedly have the STM32F103C6T6 chip, so I assume low/medium + PC13. Notably, my green LED is _not blinking_ when I have it hooked to serial.

[@martinbonfiore7871]

Best stm32 bootloader tutorial out there! Question: I have a "Pill" board that is the same as the F103 however it has an F303 chip on it. The binaries you reference don't have an entry for the F303. Can I use the F103 bootloader binary? TIA!

You just saved me about 15 hours work! thanks Sooo much man.... works first time, exactly as you have described.... cheeeers!

[@ecmroc8888]

Is there an update to this video? Perhaps a an updated link to proper files? Have tried (and tried) using updated links below But no luck. Boot loader uploads fine. But when I go to program vis USB (HID 2.2), sez it can't find the board. Thx ...

[@idus]

It seems to still require a port even in HID 2.2 bootloader. Ill try downgrading arduino IDE. Otherwise everything else I followed and it worked. Maybe usb cable.

[@MrMojo487]

"Timeout error occured while waiting for acknowledgement. Error: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again..." how to overcome this problem?

[@CalebMarting]

There's a couple possibilities. What causes that error is that your set up for serial upload is wrong. For instance If you don't have the boot zero jumper in the one position and press reset, etc. If you are sure that is all correct, try another blue pill if you have it, sometimes boards just don't work cause defective products still make them money

[@Bob-hh8rp]

hi, the cube programmer log says ST-LINK error (DEV_CONNECT_ERR) when i try to connect my st link, what do i do for it to connect successfully?

[@KaiPosadowsky]

I am a starter with micro controllers and your video was a great help. But because time goes by I faced the same problems as many people here: after first successful flash from Arduino all later flashes needed the bootloader pin 1 to set. After many hours of research, try and fail, I finally found the solution! I downgraded the version of STM32 core down from 1.9 to 1.8. STM32 core 1.9 and bootloader 2.2.2 may not be compatible, idk. Now I can upload the same reliable and repeatable way as before with Arduino nano.

[@KaiPosadowsky]

//Edit: I was able to update core to 1.90. Maybe the root of my problem was solved by installing a driver for STM32 device. My system recognised the pill as a generic serial device that helps Arduino when searching for it.

[@CalebMarting]

Ah so COM ports are not required for uploading code, but Arduino complains when there is one on your system and you don't have one selected. Maybe that was the root of your problem

[@KaiPosadowsky]

@@CalebMarting yes, but before Installation of the driver the system was not able to recognize the blue pill at all, every time after first flash from Arduino. To be complete here, the device is now a serial device and the port in Arduino fits to it.

Does it not recognize the pill, or does it even know a device is plugged in? Maybe try another USB cable, some don't have data lines

Hey same problem here. Any fix?

[@CalebMarting]

Sometimes the boards themselves are just broken, try a new board. Other times your USB cable might not have data lines so try a new USB cable

[@iMoD1998]

Old but after you flash the bootloader you need to hook it back up to the TTL converter and select the COM port and then try uploading in arduino IDE. It then begins to flash something else and it will finally work.

Followed this and was able to program the 2.2.2 HID bootloader onto a bluepill. It was attached to my linux box and I was able to program it using arduino as described. I was able to upload the blink sketch and it worked fine. What I noticed was that after programming the bootloader and plugging in the device I saw Feb 19 17:35:17 x1-Carbon kernel: [159760.782737] usb 1-4.3: new full-speed USB device number 62 using xhci_hcd Feb 19 17:35:17 x1-Carbon kernel: [159760.896087] usb 1-4.3: New USB device found, idVendor=1209, idProduct=beba Feb 19 17:35:17 x1-Carbon kernel: [159760.896088] usb 1-4.3: New USB device strings: Mfr=1, Product=2, SerialNumber=0 Feb 19 17:35:17 x1-Carbon kernel: [159760.896089] usb 1-4.3: Product: STM32F HID Bootloader Feb 19 17:35:17 x1-Carbon kernel: [159760.896090] usb 1-4.3: Manufacturer: www.serasidis.gr Feb 19 17:35:17 x1-Carbon kernel: [159760.897242] hid-generic 0003:1209:BEBA.002A: hiddev0,hidraw4: USB HID v1.11 Device [www.serasidis.gr STM32F HID Bootloader] on usb-0000:00:14.0-4.3/input0 Subsequent upload required the tty port to be set to ttyACM0, which I found strange but then I noticed that when attached it showed up as a different device.

All works fine, but I thought it was strange that the device idVendor changed from 1209 to 0483 ? Looks like newer version of the STM package (1.9) in arduino overwrote the HID bootloader.

[@CalebMarting]

It could also be the fact that when you upload an Arduino sketchwith the settings I describe in the video it creates a serial port. It's possible that's what you're detecting since that isn't initially available when you first upload the bootloader

[@MrFatjonable]

I'm running into a weird issue with PlatformIO! I can upload the code to the BluePill but only once than the laptop says "USB device not recognized", if I re-flash the bootloader then I can upload the code again but right after that get the "USB device not recognized" error. To get to upload from PlatformIO all I had to do was add "upload_protocol = hid" in the .ini file.

[@CalebMarting]

There's a lot of options that aren't checked when you use platform IO because there's no gui. Go to 8:30 in the video and I have a config that works kzbin.info/www/bejne/g6rSn2t-ZpZkhrM

[@CalebMarting]

If you want it to work no matter what platform, you could use a C/C++ library. That way there is no hardware dependency. Something like this maybe: github.com/andrewkiluk/RSA-Library Let me know if that works

Im getting “data read fail”, “GetID command not acknowledged” and “read protection” errors on the stm32cube software on all my 5 blue pills, despite it reading the chip information just fine. Any clues as to what may be happening? Great video regardless.

[@michaelharwerth4553]

I was stuck with the 'Error - [1209:BEBA] device is not found' issue as well and finally could resolve it by setting the "Tools->Port" in the Arduino IDE to the virtual COM port the bootloader had opened. Regardless the fact that the upload does not need the COM port, Arduino IDE seems to do.

[@CalebMarting]

I might not have been as clear as I wanted to be, for whatever reason Arduino needs comport selected, Even when the upload protocol doesn't actually need it

I'm sorry but sometimes hardware is just finnicky... You can turn one of your blue pills into an ST-Link v2 and program/debug with that, which works pretty well. If you want to join the discord linked in the description I can walk you through how to do that

Unfortunately you can't use ST-Link for serial, however you can still output serial over the USB port. You can have the ST link and the board plugged in at the same time, just don't plug in the 3.3 volt line from the ST link

But after all that i found the stlink actually more convenient since i dont have to unplug and reset jumpers everytime like i have to with usb.

It didn't work for me, when I upload the bootloader and reset the board, the led on pc13 blink pretty fast. Then I tried to upload a sketch and didn't work.

My question, is the HID method with the STM32F401 board is not listed under the Binaries I downloaded, it has the STMF103 and the STMF407 but not the F401's. Is there a binary file you can point me to for the correct HID files, I have versions 2.2.2 from the github. I have not been able to get the board to function, When I started, the on board led was blinking and the red led was on, now after trying the STM Cube Programmer to load the binary F407, it just showing the red power light now. I have moved the boot switch to the correct position and after STM cube indicated a download complete, I move the boot switch back to its original position. any pointers appreciated Thanks.

Hey. I know this is an older-ish video, but do you know if you can program the blue pill with STMCube IDE? Or with STlink utility or STM Cube Programmer. I just want to upload what I code in the IDE to the board via USB, be it directly or writing the binary file.

[@CalebMarting]

You could use the command line hid interface to upload bin files directly, though I'm not entirely sure how to do that. It's in the same repo as the the bin file

hello, not long ago I got the Blue Pill F103C8T6, and I am about to buy an ST LINK V2, but I am not sure what is a Bootloader ? Further I have heard something about decreasing the STM32's capacity. Does the bootloader mean you can use the board with the USB ?

[@CalebMarting]

I would definitely recommend buying the Stlink, it is worth it. The bootloader let's you upload arduino code over the USB, instead of needing an external programmer. However a bootloader will use 2kB of memory. An ST-Link v2 let's you program easily and debug your code. Also, you can still use the USB for serial output even if you are using an ST-Link, you just can't upload code over the USB without the bootloader. One more thing, if you are using a bootloader and upload code with an Stlink it will overwrite the bootloader and you'll have to reupload it If you want to use it again Hope this helped

Once the sketch is uploaded in Arduino IDE (PlatformIO as well) I get "Error - [1209:BEBA] device is not found" on all subsequent upload attepmts. The only fix is to upload the bootloader again through STM32CubeProgrammer. What I'm missing?

[@CalebMarting]

You need to have the correct USB settings as mentioned in the video, such as Usb support. Also if your Sketch us using HID you can get some interference. If you move the boot1 jumper to the one position and press reset, it will put it in bootloader mode and you should be able to upload again.

[@CalebMarting]

We found two causes for this 1. Defective/knockoff chips 2. Failed upload To fix the 1st, try a different blue pill board, they're so cheap that you should probably just buy them in pairs or triplets. To fix the second, perform a full chip erase in stm32 cube prog and then upload again. You can try it one or two times. More often than not we found it happens with defective chips but it can't hurt to try uploading again after a full erase. We can provide more info in the discord linked in the description

[@KaiPosadowsky]

Maybe you just try 1.8 of STM32 core, that helped me. 1.9 may have problems with 2.2.2 of the bootloader, maybe.

[@SergiyGryb]

Thank you for video! ...the issue is that the new STM32 core package produces larger images than the "old" one... So, might be critical for large applications that utilize almost all flash memory; could happen it would not be enough memory to flash a re-compiled app... Also, you do not need Cube to flash bootloader using STLink. You may use STLink utility (available at ST.com) to do it...

EDIT: Okay, I found out how to fix that! In my case it was bad, cheap chineese clone of programator PL2303. If you have one of these, you need to find drivers from 2008 (3.3.2.105). They will work on Windows 10. The new ones just block the chineese versions from working. Aside from that, check all the cables if they stick, and don't forget to choose the correct port, in Cube32Programmer in UART configuration, check if other COM ports appear :)

I think when it says "please restart" just unplug and replug the ST-Link and try again. You may have to be quick but I don't believe it matters, it should lock it in DFU mode

[@CalebMarting]

So that com3 error means nothing, it's just a side effect of how Arduino typically uploads. You're mainly interested in the device not found error. That can be caused by an upload of the bootloader that didn't function properly, so first try reuploading the bootloader. It can also be caused by a faulty device so if you have another blue pill please try that too

Another common problem for Mac user (I know how you feel), if you have tried everything mentioned in the video and it says something like the COM port is busy, try changing the USB-C port with another one. Sometimes it just works.

NOT WORKING!!! My Arduino IDE throws an error saying "Failed uploading: no upload port provided". I used ST-Link V2

[@iMoD1998]

After you flash the bootloader you need to hook it back up to the TTL converter and select the COM port and then try uploading in arduino IDE. It then begins to flash something else and it will finally work.

Hi, Great Tutorial. How can we do the same thing to Maple mini which does have any jumpers ?

[@CalebMarting]

static.leaflabs.com/pub/leaflabs/maple-docs/0.0.12/bootloader.html This page says you need to tie pin 2 to ground (boot 0) and in the process would be the same. Although I believe the maple mini comes with a bootloader, and you may want to use their official bootloaders as well

[@bennguyen1313]

I've been playing with the Blue Pill and the St-Link Flash utility, and I think I might have erased chip including the built-in embedded boot loader.. is that possible? The reason, when I switch the BOOT0 jumper to 3.3v and power the board, I see the UART1 TX pin from the Stm32 stay LOW... but I've read that if the ROM bootloader is running correctly, its TX line output should idle HIGH. I tried sending 0x7F (even parity) anyways, but no luck.. no (0x79) response from the chip on UART1 (B7/B6). I also tried UART2/3 (A3/A2, B11/B10). Is there a way to verify if the embedded bootloader is still there.. or restore it if I've clobbered it? As a test, I was thinking jumping to the bootloader from my application but I can't find the address where to jump. AN2606 says the for medium density devices like the F103C8, that the chip id is 0x410, but only lists the *bootloader id*/address (0x10/0x1FFFF7D6).

[@CalebMarting]

The UART bootloader is in rom and cannot be erased. However the chip itself could be fried for some reason. Do you have an ST link or another blue pill? You can make the blue pill into an ST link and potentially still upload code to the one that's messed up. I should have a video coming out about that soon

[@bennguyen1313]

@@CalebMarting yes, the chip seems to operating otherwise normally.. I can still program it with the st-link (swd interface). Long-shot, but perhaps it is in DFU mode, but somehow thinks the upgrade is coming from USB/CAN/I2C/SPI and therefore its disabled the uart? Seem unlikely as aside from power via the usb-micro, all the other pins are open.. but not sure what else to make of it!

[@CalebMarting]

Those pins might have just been fried too cuz I've heard other people have fried only specific pins. Very weird. Perhaps there's some sort of protection feature? Maybe you could use STM32 cube programmer to do a full chip erase, see if that helps

[@bennguyen1313]

@@CalebMarting Thanks, you gave me a great idea.. test the pins by writing a program that uses UART1... as I was doing that, the Device Configuration Tool shows UART1 to be on P10/P9! Using those pins, the DFU worked! I goofed when I was using a very colorful popular pinout diagram of the blue pill that shows RX1/TX1 on B7/B6..I thought the outer most columns were the default pins, and alternate functions on the inner ones... apparently, that's not the case!

[@henrycheung6960]

Thanks for the video. One question, with HID bootloader, do you still need to move the boot0 jumper each time when uploading the sketch?

[@CalebMarting]

No, The HID bootloader is essentially a sketch that can store more sketches alongside of it. it will run the hid bootloader to start and then it'll start running your uploaded code. because that hid boot loader is always running you won't ever need to move boot zero

There might be something funky going on with your board, unfortunately quality control on these really isn't that great, they should at least be bought in pairs. Does your LED blink fast when it's plugged into the computer? If it's not blinking really fast when you first install the bootloader then it won't work. Do you have another blue pill you can try it on?

@@CalebMarting ​ Sadly, this is my first time working with blue pill, I only bought one. Yes the LED did blink very fast....

Other time, it would return Error: Write address not acknowledged: 0x8000B00 I think there is something wrong with the flash memory, I tried to read the memory with stm32cubeprogrammer, certain address return the same error as above, but was able to read sometimes if I repeat it a number of times.

[@raulkompass2773]

I possibly had the same problem: My Bluepill could send messages via serial over ttyACM0 but it was not possible to flash it a second time. The bootloader was not active anymore (no fast blinking), but the slow blinking occurred according to the example I had programmed. The Solution was to reset the board (or power it up) while the BOOT1-jumper was set to 1. The other jumper! Then the fast blinking reoccurred and I was able to flash it with HID Bootloader method. After resetting I could set the Jumper back to 0. Thus after reprogramming the board the USB-Serial automatically re-activated. Perhaps this should be added to the instructions. Now I'm very happy with the solution: Small bootloader and defined switching to programming via jumper. No STLink or USBtoSerial adapter needed anymore. Many Thanks Caleb.

Not working at all for me...either on Windows 10 or MacOS. Bootloader working successfully but this business about the virtual com port...is that a software driver that needs to be installed from STM? Otherwise, device not detected at all...

[@CalebMarting]

The com port should have the driver by default on Windows 10. When you first install the bootloader though, the com port will not be there. This is because uploading with the settings described, generic CDC supersede usart and USB enabled will create the com Port when a sketch is uploaded for the first time. However sketches are actually uploaded over a hid device meaning that you don't actually need a com port to upload code. However Arduino is a little janky and requires a com port be selected if one's available.
