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!

[@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.

[@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!

[@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

[@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?

[@walterhynson2898]

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

[@OmarElmasry1]

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

[@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

[@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

[@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!

[@MrSudni45]

thank you for your video, now my 'Blue Pill' work well with Arduino, and serial output it's great to help to display info or debug. Great job.

[@InterdimensionalWiz]

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

[@CalebMarting]

The first time I uploaded a bootloader it took about 15 hours to figure out how to do it. That's why I started making these, to save people time. Glad it works!

[@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...

[@sakugava]

Thank you very much. Worked like a charm!

Amazingly simplified Video ever made , I came across ....You are a real Gem knowledge sharing sole ! Keep doing your good work for the community ! is there any similar video for STM8 boards I can refer ?

[@CalebMarting]

I haven't used any STM 8 boards so I'm not sure, if you need any help though I'm sure the process is similar

[@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.

[@van-nhantran1915]

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.

[@thermalwire6614]

Thank you very much very good your tutorial worked perfect you unless my stm32 do not go to the trash

[@OpenLogicEFI]

The way you address the comments section is hilarious!

[@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.

[@allinonesolutionsbd]

Thanks a lot. I got my first stm32 project.

[@simonsunnyboy]

Thank you for this tutorial. I could make it work under Linux (XUbunut 18.04) but I have some remarks: $ uname -a Linux mybox 4.15.0-99-generic #100-Ubuntu SMP Wed Apr 22 20:32:56 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux - The STM32 Cube Programmer doesn't work here under Linux but I could flash the HID bootloader binary without problems using the st-flash utility via my ST-Link clone. I did this outside of the Arduino IDE, it was as simple as "st-flash write hid_generic_pc13.bin 0x08000000" on a blank Blue Pill - The udev rule configuration for proper detection of the HID bootloader as described on the bootloader github should be in place and active before opening the Arduino IDE. - The created virtual COM port seems to jump back and forth (/dev/ttyACM0 and /dev/ttyACM1) if the reset button is pressed or the cable is reconnected. - Using the virtual COM port works only after the flashing. One cannot open the COM port and flash in parallel, e.q. open the serial monitor later. It may even be necessary to change the COM port. - I get kernel messages and error messages inside the IDE regarding the COM port.

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.

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

[@randallyoung9411]

Important to be persistent with this, I used the usb SWD programmer, stlink v.2 to flash, simply because it was convenient, and I had to finally erase it three times, and then program twice in succession, to get the new HID 2.2.2 bootloader to enumerate correctly on Window 10. Be sure to use a known good usb cable, and I had to use my older 2.0 version USB connector, not my new USB 3.0 ports I added via a PCI-e expansion card Once you get past the initial flash, it will create a serial port that works perfectly as a CDC serial port (COM44 in this particular case). I also tested the hid_flash (v2.2) from the command line like this ... "hid_flash>hid-flash.exe C:\Users anda\AppData\Loca\Temp\arduino_build_363784/Serial_Test_Arduino.ino.bin COM44" All OK! (As always, don't be shy to connect/reconnect the usb cable to power cycle, and/or press the reset button if something appears to hang)

"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

[@upendrachaudhari4635]

very cool, i had so much trouble with this in the past

[@manuel_youtube_ttt]

Even though I had uninstalled all smt32-related stuff from the UI, I still had in the `C:\Users\MyUser`Documents\Arduino\Hardware` some folder called Arduino_SMT32-master that I surely put there some day in the past from some other method. That's also the reason why my UI in "Tools" looked different than the one showed by Caleb. Once I deleted the folder, my UI started looking normal again and I was able to select all the right options that he showed. Finally, I had to manually select the right COM port at the time of my second upload and that was it now my Blackpill f103C8T6 works perfectly as the Bluepill shown in the video.

[@CalebMarting]

Do any devices show up in the device manager when you plug it in? That's very interesting. Try moving the boot one jumper to the one position and seeing what happens

[@manuel_youtube_ttt]

@@CalebMarting Sorry I edited my comment to make it more concise after I found my mistake, I think you answered to the original one. However... now I tried uploading my own sketch instead of a simple led+Serial and I've lost the COM port that had appeared and I'm unable to program the Blackpill again (the "1209:BEBA" error).

@@CalebMarting I found why my sketch did that: "Wire.setClock(400000L)". Apparently that's the cause. When I don't have it, my bootloader continues working for another round.

[@avendite7206]

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 :)

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

[@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.

This should work with black and blue pill boards, I just happen to have blue pills. Thank you for the feedback Edit: to anyone reading this, I was informed that black pills actually refer to F401/f411 boards which this is not compatible with. I am releasing a new tutorial for that

Caleb Marting, First thanks for you nice video's. I am a NOOB and have used your guide with Win10, STM32F401, I am using the ST-Link V2 with the latest firmware. 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.

[@CalebMarting]

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

[@maty-ro7wy]

// This method did not work for me, I was able to finish the process and load the "Blink" example, but after loading my own code, the PC did not recognize the blue pill board. I have resorted to your previous video (2018), and the previous method has worked for me wonderfully.

[@KaiPosadowsky]

Try again but with 1.8 of core and not 1.9. This worked for me. //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 recognizes the pill as a generic serial device that helps Arduino when searching for it.

[@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.

Finally have a windows box that I can play with and found this. Does one still have to replace the R10 Resistor? That was the other thing that has held me back in the past.

[@CalebMarting]

I haven't had to replace any resistors yet. If you do need to replace a resistor, You also can jump one of the pins with a standard value through hole resistor and it accomplishes the same thing. amitesh-singh.github.io/stm32/2017/05/27/Overcoming-wrong-pullup-in-blue-pill.html The main issue I've had is either off-brand or faulty chips being installed on these for cost reasons and not working correctly.

Is this bootloader version still the most current for STM32?

[@pa6552]

Hi - thank you for these videos - very helpful! I hope you can find the time to help me - I bought some STM32 boards that seem to be using this chip: STM32F303CCT6 with 256 KB Flash - Robotdyn is the manufacturer. The binaries in the links you posted are for F103 and F407 only - does this mean my board cannot be flashed with a bootloader?

[@CalebMarting]

Hello! The f303 supports DFU upload, so you actually do not need a separate bootloader to upload code over USB. you can find this info in section 3.5 of the official datasheet. www.google.com/url?sa=t&source=web&rct=j&url=www.st.com/resource/en/datasheet/stm32f303cb.pdf&ved=2ahUKEwiv95CQ3LbqAhVGCc0KHQieDuoQFjAAegQIBRAC&usg=AOvVaw316i_atPeBiw5Z2kVGDzC4&cshid=1593973002676 Please take a look at my black pill video, the process is essentially the same for uploading code! kzbin.info/www/bejne/mGKUY2ahr8Rmg68

[@pa6552]

@@CalebMarting Thanks for the prompt response! I cannot get my Windows 10 PC to "recognize" the STM32 board, hence why I thought I needed to flash the bootloader. Is this just a USB driver issue then, and if so do you know where I can find the correct driver?

Do you have the boot pins set correctly? You may need to install a driver too, I am not sure

If I upload a bootloader in stm 32. After uploading does I still need a programme or st link to program the board. I new with mcu's. So please clear

[@dmitr8194]

Excellent! Can I use stm32cubeide for programming and upload that loader? Where I could see instruction?

[@CalebMarting]

You can probably set it up but I haven't seen anyone get that working yet. You'd basically need to have a script that runs for upload when the binaries are generated. Again I'm sure it's possible. I would recommend an ST Link V2 if you actually want to use STM32 cube IDE

[@van-nhantran1915]

If anyone follows this tutorial on MacOS and having the error: hid-flash permission denied, you need to open terminal and add the execution permission to hid-flash file. After that, you can upload the code as in the video.

[@CalebMarting]

That would be a good thing to make an issue for in the GitHub repo. Thanks for bringing that up!

[@CPlusTravel]

For first upload, I don’t need to select com port. For subsequent uploads, I must select the port or else it will fail to upload. For some weird reasons my led blink program is not working properly. I changed the delay time for “high” to 1200 ms and “low” for 200ms. The blink is working the other way around and seems high on 200ms and low on 1200ms.

[@CalebMarting]

I forget, some boards have inverted LEDs just because of the way they were wired. It's possible that's what you got. And yes the com port thing is just a side effect of how the Arduino framework upload is written

[@CPlusTravel]

Thanks.

[@CPlusTravel]

Btw, I try loading another sketch and it doesn’t recognize the com port anymore. I redo the bootloader and never get back to work.

[@CalebMarting]

You can move the boot1 jumper (the one that isn't touched during install of the bootloader) to the 1 position and reset the board. It should make the boot loader start working again and you can upload code. Make sure that you have USB support turned on when you upload code though or else you will have to keep moving the jumper

[@CPlusTravel]

Caleb Marting thanks. I redo the flashing via cube programmer and it works again. Now uploaded more than ten times without issues. Thanks.

Spent hours on messing with this without success, any hints?

[@CalebMarting]

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

[@JamieJones1985]

@@CalebMarting I might try one of the other bootloaders or a different vendor, or stick with stlink v2. Is it possible use stlink for serial output?

[@CalebMarting]

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

[@HoangoKidZero]

In my case, I have to choose a COM port in order for the uploading process to be successful. Do you know why that is?

[@CalebMarting]

I think It uploads fine The first time without a com port selected for me, but then I have to have it selected too. I think the reason is Arduino has an old check that makes sure there's a com port selected when uploading because It was designed for the AVR chips that upload over com

[@pranavmokashe1637]

sorry but one last question . Does the USB connection get disconnect and connect during the upload process ? please reply?

[@CalebMarting]

No worries, I don't know, typically that doesn't happen to me. You can try uploading the bootloader again, and if you want try doing a full chip erase using the cube programmer and then uploading the bootloader again. Also check to see if your chips are a knock off, they might say CKS or something instead of ST

So, yeah, 2k for a bootloader sounds much better. Now just show it in Linux. You might want to note the OS in the vid/title as well. The issue I have had with PlatformI/O is it's slow speed on my old laptop. I'm building a better dual boot machine with W10 atm, but still cringe every time I use windoze. BTW, I have a STM32 playlist (references to other people's stuff, like this vid). One thing I recall seeing/saving is an upload someone did showing how to unlock the full 128k of memory on the 64k limited parts. I haven't tried it, but that looks interesting. Apparently all part numbers within a family of STM32 chips have the same die. I've heard, in the past, the part numbers were used for graded chips, separating them according to what worked/didn't work during production. As the yields have gotten much better they are using fully functional chips to fill orders for lower grade part numbers and just limiting the integrated peripherals in the internal registers, but this can be reversed :-) -Jake

[@CalebMarting]

I've looked into doing the 64 to 128 conversion. Haven't ever gotten it working yet though. This should theoretically work with Linux and Mac as well because I believe the STM32 cube prog and hid bootloader work on those systems too. The process should be almost exactly the same. If you ever try it out let me know how it works.

[@ritwikkaushik4026]

Thanks for info but in my case after installing the bootloader when i plug my STM32f103 bulepill it says USB not recognized and in arduino IDE it says your board is not connected,but i think bootloader is flashed as mine PC13 led is blinking at very high rate.Any ideas?

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.

What would you need to upload when using the STM32F303 ? Could the same bootloader be used as the Blue Pill?
