Help!
I have an STM32 which I have been using and programming but tonight, it will no longer connect to
my XP machine as a COM port so I can't program it.
I first noticed in the Maple IDE that the serial port was not seen so I looked at the
Device manager.
When I first connect the STM32 to my PC USB port I see a LibUSB-Win32 device show up momentarily in
Device Manager but then it disappears...
I shut down my PC but rebooting didn't help...
How can I fix this so that my PC registers this device?
Thank you
Hello japper,
Try uninstalling and then installing the drivers again.
Follow these instructions:https://www.olimex.com/Products/Duino/STM32/OLIMEXINO-STM32/resources/Olimexino-STM32_Installation.pdf
(https://www.olimex.com/Products/Duino/STM32/OLIMEXINO-STM32/resources/Olimexino-STM32_Installation.pdf)
If still fails try the installation instructions here:http://leaflabs.com/docs/maple-ide-install.html (http://leaflabs.com/docs/maple-ide-install.html). The dfu drivers might be found in the Maple IDE folders.
Of course, there is always a tiny chance that you have somehow managed to corrupt the bootloader or the board has received some sort of hardware damage.
Best regards,
