error when uploading sketch?

[8bitbunny]

so i try to compile my stuff, which succeeds, then my Arduino IDE wants to upload it to the board, the blue flashing led goes off, and i get an error message "There was an error during upload with uploading the sketch"

however, when i reset my dragonfly (reset switch), it simply runs the initial bootloader blinky again.

my IDE version: Arduino.cc IDE 1.6.11 Latest board package (had the same with version .16 which i had before) OS:win 8.1 which is up to date (including drivers)

could it be my 'programmer' setting? i currently tried the st-link, stm32 bootloader, and arduinoisp

Can you let it run first till it blinks green ? The blue blinking is the formatting of the SFLASH, which takes a few minutes.

Does Windows show the serial port device properly ?

[8bitbunny]

the green led is LED on and the blue LED is blinking, plus once i plug the board in, i get the device in 'my computer' as should.

the Serial port is there, i tried it on a usb 2.0 and usb 3.0 port, same issues

i also tried cwapping drivers with Zadig, no success

[8bitbunny]

update: i have let it blink for half an hour now, and realized this was the first sketch that i got to work a period ago, so it's normal the blue led flashes.

but now it fails somehow...

also, the ide gets the dragonfly in bootloader mode (no leds on), when in bootloader mode, i can only see the device in device manager (device status says this: device won't start)

[GrumpyOldPizza]

Can you use Zadig when the device is in bootloader mode to associate it with "winusb" ? Perhaps Win 8.1 decided to install another driver there ?

I'd switch the device manually into bootloader mode by press/release the RESET button while holding the BOOT button.

[8bitbunny]

still the same error in arduino, though the device is recognized as "STM32_BOOTLOADER" in the device manager also, sorry i'm so late, didn't had the time to continue testing and simply forgot after..

Did you use Zadig to put winusb on the STM32 BOOTLOADER device?

yes, also, going to try another pc now, checking if it's a software config issue

[8bitbunny]

i can confirm it is a config issue on my pc, as it works on my second laptop, but where else to look for..

edit:

only thing i know of is that i have Axoloti dsp's (aka stm32f4 mcu's) on my main laptop as well (having different DFU flashers), i wonder if that's an issue?

[GrumpyOldPizza]

I have no idea what the issue is with your PC. Perhaps having 2 devices with the same VID/PID might be an issue.

[8bitbunny]

don't know, i do know it's working on my older laptop, which is good enough for me :)
