STM32 USB bootloader error on Arduino IDE

[shashank98]

Hi,
I'm trying to load the USB bootloader on my STM32 blue pill, but am getting an error while uploading the sketch of a simple blink (in built LED). Have attached a screenshot of the error message along with the error report log for reference.

• I have run the same code with an FTDI and it works.
• I've followed exact same steps as in this below article. The components I'm using are exactly the same as in the article
  STM32 Bootloader, STM32F103C Programming using USB Cable

Environment used:

• Arduino 2.0.0
• Latest Java (JDK) version 19 - Java Downloads | Oracle

Any suggestions or help would be appreciated. Thanks and have a nice day!

I don't think you are doing the same as in the article. in the article they use Arduino IDE 1.8.15 and your screenshot shows Arduino IDE 2.0.0

Yes, downgrading to 1.8.15 worked, although I'm not sure why it doesn't work with an updated version of Arduino IDE.

2.0.0 is not a simple update, but a more or less complete redesign of the IDE. Libraries and cores that were compatible with V1.x.x need to be checked and/or adapted for compatibility with V2.x.x by their maintainers.
And since V2 has quite a bit of pending things that still need to be implemented (e.g. portable installation) I can imagine this is going to take a while.
I will stick to V1 for the for the foreseeable future, until V2 is complete.
