(SOLVED) Cannot Upload to STM32F103 "BluePill" using ST Link on Nucleo Board

I have read through so many threads over the last few weeks and have still not been able to resolve this issue.

I am connected to a clone bluepill STM32F103C8 board with 128k using the attached STLINK SWD interface on a Nucleo F411RE development board. I am using 4 lines (3.3v, gnd, SWO, and SWCLK). I read another thread here where the OP had very similar issues to mine and they marked it solved based on wire length, but that is not the issue here. I shortened them to 3 inches and still have the same issue. Again, it works with other methods, just not VSCODE/PLATFORMIO.

Although I can successfully upload to my STM32F103C8 (128k) blue pill clone boards using Arduino IDE v1.88, I cannot using Platformio on VSCODE. I can also successfully communicate with the board using the ST-LINK Utility v4.0.0. I have not tried to upload the firmware using the ST-LINK Utility CLI or the GUI because I do not know how. I will humbly admit that there is a lot I have not looked at and tried, because I do not know where I can find a log of the upload handshake from the Arduino IDE, or what command line parameters to use with the CLI version. I have researched that also, but only today.

If anyone that has solved this can point me in the right direction, I would certainly appreciate it! I want to use VSCODE for ALL my work, and will be happy to put the Arduino IDE behind me. THANKS!

Here is what the ST-LINK Utility says…

16:40:45 : ST-LINK SN : 066CFF545753845187103146
16:40:45 : ST-LINK Firmware version : V2J35M26
16:40:45 : Connected via SWD.
16:40:45 : SWD Frequency = 4,0 MHz.
16:40:45 : Connection mode : Normal.
16:40:45 : Debug in Low Power mode enabled.
16:40:45 : Device ID:0x410 
16:40:45 : Device flash Size : 128KBytes
16:40:45 : Device family :STM32F10xx Medium-density

If someone can direct me to where I can read up on how to get the output from the Arduino IDE then I will be happy to include that here as well.

The code I am uploading is a simple blink program.

#include <Arduino.h>
#define ledPin PC13 //13
void setup()
{
  pinMode(ledPin, OUTPUT);
}
void loop()
{
  digitalWrite(ledPin, HIGH);
  delay(800);
  digitalWrite(ledPin, LOW);
  delay(40);
}

This application works as expected when compiled and uploaded using the Arduino IDE v 1.88. This also compiles without issue in Platformio on VSCode with no issues.

When I try to upload the code in Platformio on VSCode using the icon button (right pointing arrow), this is the output (the tail end of it).

Have you made an additional changes you haven’t mentioned? Why is a higher debug level used?

I’ve just spotted this sentence. That’s not correct. It should be:

Signal Pin on Nucleo Pin on Blue Pill
3.3V 1 4
SWCLK 2 2
GND 3 1
SWDIO 4 3

In particular. SWDIO instead of SWO.

1 Like

Close all other programs which use the STLink, like ST-Link utility. I think it just can’t open the adapter.

In addition to what @manuelbl said, make sure that you follow the Nucleo user manual chapter 6.2.4 exactly.

grafik

Doube check pinout and that you removed the two jumpers on CN2, so that the STLink is not connected to the original STM32 MCU on the Nucleo board. (There’s also an “IDD” jumper there, you can pull it out to ensure the lower MCU has no power).

Good Morning Sir, Happy New Year!

I should have been more clear, sorry for the confusion. I was reading off the blue pill pin assignments from the board, and yes I did think that SWO was odd but it appears that is all they had room for. The Nucleo does not have the pin names available on the board. Believe me, I have checked these connections several times against the datasheet, thinking that was the cause, but then remembering that I was successfully able to upload the firmware from the Arduino and the same setup persists as I have not changed anything. I even confirmed what the Arduino IDE already told me by switching the delay values in the program to affect the duty cycle of the blinking LED, so I could visually confirm. Also remember that I can connect with the utility and read the board. This is where I got the output from STLINK to post here.

Also, here is the new verbose output from VSCode/PlatformIO. Thank you for the debug level suggestion!!

Good Morning Sir,

See my reply to manuelbl that replies to your post also, with the additional info that the verbose output I shared was in an environment where I had nothing else running that is related to that COM port, or anything actually except my browser. Also, I have tried to flash unsuccessfully with platformio with NRST connected to the target’s RESET, and not connected. At other times when I was successful (a couple of years ago), I did not connect the NRST then either.

My posted picture shows my jumper settings on the Nucleo. I believe they reflect what you replied with. I believe I got my setup info from the same source because I recognize that info and believe it is in the manual. Thank you for the effort!

@manuelbl and @maxgerhardt, I should have wrapped this all up in one reply. My apologies, I am still learning this environment.

I am just guessing here since I have not used my DSO on this yet. I wonder if the timings are more loosely tolerated using command line parameters from the Arduino IDE than they are from platformio. I know there is some variance in design and quality with these blue pill boards. Unfortunately, the one I am posting about is part of a 50 count batch I bought a couple years ago. Quite a few of them worked fine back then, but I could not for the life of me get them to work as I2C SLAVES, so I mothed-balled their use as I worked with other processors. Now I have another application for them but here I am hitting a brick wall again.

So because these vary so much, I would not know if any specific BUILD-FLAGS would fix this, but I would like to see a variety of those that worked with the STM32F103C8. I cannot seem to find that info anywhere, or how I can see what Arduino IDE uses. I do not know the path used to OpenOCD either and wonder if the versions are different, or the scripts, between VSCODE/PIO and Arduino IDE. I did find a few active instances on a few of my drives.

Thanks for the help and I hope this extra info makes sense to you.

Thank you for your time!

My bluepill board reads “GND”, “CLK”, “IO”, “3.3”, so no SWO here, but GND,SWDCLK,SWDIO,3.3V, as it should be.

When I just tried this setup I might have um… shorted something… because now my VDD_TARGET pin on the SWD header doesn’t give 3.3V anymore. So I plugged it directly into 3.3V in the “Power” section of the Nucleo board.

But this works now.

Can you please open the Windows device manager to check if the there are unknown devices? There should be a line saying

I again highly suspect that there is just a driver issue with something and it cannot recognize your STLink, thus “open” fails in OpenOCD.

You might also need a firmware upgrade of the STLink, downlodable from STSW-LINK007 - ST-LINK, ST-LINK/V2, ST-LINK/V2-1, STLINK-V3 boards firmware upgrade - STMicroelectronics.

Thank you for that info. I am also powering my STM32 from the lower half of the Nucleo. That target power is a reporting pin (I thought) to report if the target has power before proceeding. Someone told me it was a high-impedance switchable port but I never checked the schematic to confirm. I believe I did test it with my DMM once though and got the same results as you.

I am curious, isn’t OpenOCD used by Arduino IDE? There is a file size and date difference between the two instances of OpenOCD.EXE I found.

Are you using anything special in your platformio.ini file? I would love to see what you have in there. I remember something about build-flags that fixed this for me last time, but I cannot find that info anywhere!!

My ST-LINK appears to be functioning normally with the latest driver.

Serial Driver

I used the same as yours (with commented out extra dirs)

[env:genericSTM32F103C8]
platform = ststm32
;lib_extra_dirs = ~/Documents/Arduino/libraries
board = genericSTM32F103C8
framework = arduino
upload_port = COM4
debug_tool = stlink
upload_protocol = stlink
build_flags = -DCORE_DEBUG_LEVEL=1

though it must be said that upload_port = COM4 makes no sense since it uploads via the USB device of an STLink, that is ignored. Only when doing serial uploads, that would matter.

Can you try the firmware upgrade program and see if that makes a difference?

After that you can also try and change

upload_protocol = stlink

to

upload_protocol = mbed

on “This computer” there should be a “NODE_F411RE” virutal USB drive. That is opened by the STLink and accepts copying a firmware.bin file to it, that the Nucleo then tries to flash to the board. Usually done for mbed boards, but works on Nucleo boards, too. If that doesn’t work either, something is wrong with the STLink.

@Hop Thanks for the image. I spot two problems:

  • The boards are incorrectly wired. On the Nucelo SWD connector, pins 1 – 4 should be connected, not 2 – 5.
  • The Blue Pill should have an independent power supply, either via USB or some other 3.3V source.

VDD_TARGET is mainly used to measure the voltage of the target, not to deliver power. Some ST-Links can provide power as well but I’m not sure about the Nucelo’s ST-Link.

OK, I know I tried MBED before because I have it commented out in the ini file, so I changed it back, and now I am showing that the firmware.bin file is not found. The output is below.

By the way, I did drag the firmware.bin file over to the NODE_F411RE drive and it flashed just fine. The ONLY issue I had was that I had to press the reset button for it to run, and I cannot find an option to fix that like you can with the automatic mode dialog window in the utility.

Here is the verbose output (MBED UPLOAD). I would imagine that not being able to find the firmware bin file would be a real deal breaker. I wonder why, and where I can repair that.

This is what I have for the SWD on the Nucleo. As far as I can see, it is also the same on the discovery. The first pin is the VDD_TARGET like you mentioned and is not used. So I am using 2-4. Pin 5 is connected (NRST) with a jumper but is NOT used and not connected to RESET on the STM32F103. 2 is SW Clock, 3 is GND, and 4 is SW DIO. Besides, it has to be hooked up correctly because I use to be able to connect, a couple of years ago, and I reconnected this based on images and data from that time period. Also, Arduino IDE and STLINK are able to upload without issue, which would not work if my connections were incorrect. UNLESS for some reason, the command line arguments from OpenOCD include using VDD_TARGET to confirm connection. Hmm.

EDIT: And I have always used the 3.3v on the F411RE board for power. I am not sure why it is not available on the SWD port. Maybe it is not a best practice to use the power from the NUCLEO attached target board. I have never had any problems though. Usually, when I have other devices connected, I already have a power bus set up, instead of just powering the target.

You are correct. By looking at the connectors on both boards, I’ve counted 4 wires. But there are 5. And with your description, I also understand where the brown one goes.

@maxgerhardt, @manuelbl I GOT IT!!! YAY!
Thank you max for the nudge in the right direction. Indeed, upload_port was not needed, and when I commented it out, the upload worked! I looked over the last failed verbose output and noticed that the path of the firmware that was not found was COM4/firmware.bin. This is really odd actually that the firmware would be expected at a subdirectory of COM4 just because a com port was used. Weird. I am sure there is a reason.

Anyway, the only issue I have now is that the board does not auto reset. Perhaps the use of the NRST line might be for this purpose. Checking…

And indeed it is!! I will have to use my scope to see if there is a pulse on that line, but after I wired it up, the application ran as if I did a hard reset. Now that is TWO long-term issues solved.

Thank you gentlemen for your help and suggestions, I appreciate it!!

EDIT: [after-thought] - Also, Max, I appreciate the tip about the MBED drive and dragging code over to it. I would imagine that the same result would occur if a firmware file was copied to that path via a script. That would almost completely negate the need to jump through all those hoops with OpenOCD! I wonder if I can set PIO to just run a script and copy that file over when I wish to upload. I’ll have to explore that someday.

This happened because when using upload_protocol = mbed, then upload_port is respected, as the path you want to copy the firmware too. If you’d want to do this manually you’d say upload_port = E:, for example.

It’s good that that upload method is working now, but then the OpenOCD upload is still not working? Without that, you also cannot use debugging, as that requires the SWD interface.

Have you tried the firmware upgrade of the STLink already? LINK Firmware version : V2J35M26 is two majors behind the current

Maybe also uninstall the driver in the Windows device manager and install them again using the latest version found in ST-Link utility (C:\Program Files (x86)\STMicroelectronics\STM32 ST-LINK Utility\ST-LINK_USB_V2_1_Driver)

@maxgerhardt Out of curiousity, that image you shared that is your version… yours was out of date also? Or am I reading that wrong? V2J34M25… mine is V2J35M26 (newer?) and the current one is V2J37M26 (newest?). I just want to make sure I got that straight. So technically, if I also had your version then it would also work? This would indicate that there is just a problem with my version, which correct, is out of date. So… just saying, if the current version does not work also, and this is the issue, then I could roll back to your V2J34M25 and it should work. Again, if the ST-LINK version is the issue. Right?

I’m on it. Thank you sir. And PLEASE correct me if I am missing something.

Yes my initial one was older than yours, but for me it worked with that older and also the newest version. So if you upgrade to the newest version as well there’s no version difference between us, and if it still fails, it must be something else.

In that case I’d ask you to open a PlatformIO CLI and execute

C:\Users\Hop\.platformio\packages\tool-openocd\bin\openocd -d3 -s C:\Users\Hop\.platformio\packages\tool-openocd/scripts -f interface/stlink.cfg -c "transport select hla_swd" -f target/stm32f1x.cfg -c "program {.pio\build\genericSTM32F103C8\firmware.elf}  verify reset; shutdown;"

That is the maximum debug output and should hopefully reveal something.

I ran what you posted but I got an error and that path “C:\Users\Hop.platformio\tool-openocd\bin\openocd” does not exist on my system. I instead tried to run it with “\packages” added and the output is below. If I am suppose to have a “C:\Users\Hop.platformio\tool-openocd\bin” folder in addition to and looks like “C:\Users\Hop.platformio\packages\tool-openocd\bin” then there might be the problem. I just figured you forgot "\packages\ in your path, after .platformio.

OpenOCD cannot find a USB device of the specified vendor and product ID pair.

What does the Windows device manager say about the PID and VID of the “ST-Link debug” device?

For me VID=0x0483 and PID=0x374B exist, so it would find it in the third entry.
