Bootloader

Post by Icesythe7 »

I purchased 3 STM32F103RCBT6 ARM Cortex-M3 leaflabs Leaf maple mini module for arduino STM32, when received I used my arduino uno to flash some firmware on them and they all work fine and as expected, however I would like to restore them to how I purchased them so I can now write my own program for them however they are now recognized as a usb device and no longer show up as a com port and I'm not sure how to reprogram them as the arduino ide can not see them anymore...what do I need to do to restore them to how they were when I received them so that I may reprogram them?

following the roger github ordeal i just get this error

Sketch uses 25308 bytes (22%) of program storage space. Maximum is 110592 bytes.
Global variables use 3128 bytes (17%) of dynamic memory, leaving 14280 bytes for local variables. Maximum is 17408 bytes.

An Internet search of Windows 10 unused orphaned Serial COMM Ports offers multiple avenues:
