I am using the tutorial quickstart for the Swan and I’m having a problem flashing the code in this section . i do not have a STLINK-V3MINI , so I connected to the swan in this section Programming Swan without the STLINK-V3MINI I was able to build but not upload. I received the following error No …

I finally was able to get it working on my PC consistantly, but I don’t know why. I installed the STM32CubeIDE and the STM32Cube Programmer and ever since then I am able to use PlatformIO and ArduinoIDE on my windows10 PC.

Here is the terminal output for the UPLOAD Executing task in folder My First Swan Project: .platformio\penv\Scripts\platformio.exe run --target upload --upload-port COM7 Processing bw_swan_r5 (platform: ststm32; board: bw_swan_r5; framework: arduino) ----------------------------------------------…

I might add that I do the following everytime before an upload as directed [image]

Hi @skruglewicz , Sorry to hear you’ve hit a roadblock with the Swan. It looks like you’re doing everything correctly, but I have a few tricks you can try: The classic “reboot your Windows PC” has fixed serial issues in the past :slight_smile:. Try a different USB cable, just in case. Triple check…

Thanks I will try to reboot my windows PC and see if that helps. I tried multiple USB cables and even used the one that is working with my notecarrier-a? So it’s not the cable. I have done the DFU boot sequence the same way many times. One thing I observed though is that before I do it the com por…

I just tried to reboot my PC and trried it again… Same problem. I tried it on another windows PC and I have the same problem the PlatformIO version is Core: 6.1.11 Home: 3.4.4 And VS code is [image] This is very wierd that it does not work?I even tried to Install a generic USB driver that su…

I ended up using the Arduino IDE and was sucessful with the example . I did not receive the DFU Connected device. I followed the tutorial at https://discuss.blues.com/t/problem-uploading-to-my-swan-mcu-using-platformio/1698/6 There must be something wrong with using VScode, platformIO or the platfo…

skruglewicz You tried to do the flashing within VSCode instead of t use the : .platformio\penv\Scripts\platformio.exe run --target upload --upload-port COM7 command. Just press the Upload icon? [image] Regards, Rob Oudendijk

I noticed an error but it seems to have fixed itsel and the Upload was able to complete. Can you make anything out of the highlighted text below? seems like the device firmware is corupt? should I get a replace ment SWAN? [image] Not sure why I was able to get this working?

To help with troubleshooting, could you try installing dfu-util from here.

When you run dfu-util -l it will show you which DFU-capable devices are connected to your PC.
