Arduino IDE "Access Denied" on Uploading Sketch

[dapostol73]

I followed this tutorial on getting the Blue Pill setup, everything went fine until I tried to upload the sketch and got this.

Sketch uses 12804 bytes (19%) of program storage space. Maximum is 65536 bytes. Global variables use 2064 bytes (10%) of dynamic memory, leaving 18416 bytes for local variables. Maximum is 20480 bytes. Access is denied.

I'm runtime Windows 11 with the latest IDE and installed the Drivers using install_driver.bat from Arduino_STM32 repository. I check my drives in the Device Manager and they say they are using 'Maple Serial (COM7)' however in the IDE it just say 'COM7' (not sure if this an issue)

Also, if I connect with Serial Monitor, the board seems to spam these lines repeatedly, which makes me assume the bootloader is working properly.

Congratulations, you have installed the STM32duino bootloader See https://github.com/rogerclarkmelbourne/STM32duino-bootloader

For more information about Arduino on STM32 See https://www.stm32duino.com

Please let me know if there is something I'm missing or an issue running this on Windows 11?

I don't know how WIn11 manages the ports but from your post I think that Arduino access to the port is prohibited. Have you installed the serial driver with admin right? Try to start Arduino with admin rights.

@dapostol73 If you talked about IDE 2.x, take the note that you must to close a Serial monitor before uploading the code to the board.

Hi @board707 Yes, the Serial Monitor is close when uploading. I just used it to confirm that the bootloader was up loaded successfully and is working.
