Here are the main advantages of UF2 Bootloader: -no need for any third-party driver or reflashing software. -The firmware can be Identified by the keyboard. Only the firmware for the current keyboard will be reflashed. -You can read your keymap from the current firmware from the USB disk of the bootloader.
|The keyboards with UF2 bootloader|
Note: STM60 sold before 2019.3.8 used STM32 HID Bootloader.
The method of reflashing firmware is the same under Windows and Mac.
If you don’t want to re-plug the USB cable to enter bootloader when you are using the keyboard. You can press LShift+RShift+B of the keyboard at the same time, then the keyboard will restart and at the same time immediately hold down Esc. This can also enter bootloader to reflash firmware.
That's because the UF2 file dragged in may have some problem or it is not for the current keyboard. Check it and drag the correct UF2 file.
If the keyboard still enters bootloader after reflash, the wrong firmware may be flashed. Please check and reflash the correct firmware.
If it is displayed as unrecognized hardware, the wrong firmware may be flashed. At this time, re-enter the bootloader, and reflash the correct firmware.
