dRonin on a brushed micro oughtta be fun!
This FC ships with BetaFlight 3, got dRonin loaded like this:
The boot pads are located on the opposite edge of the board from the USB connector near UART1. Connect the FC in DFU mode by shorting the boot pads while you plug in the USB. You may first need to update drivers for the ST32BOOTLOADER with Zadig to get the DFU connection to work.
Another way to get BetaFlight 3 into DFU mode without shorting the boot pads (or even knowing where they are):
- connect using BetaFlight Configurator
- in the CLI tab enter the command
Once you have the FC in DFU mode, open BetaFlight Configurator (or any *Flight Configurator) Firmware Flasher:
- enable No Reboot Sequence
- disable Full Chip Erase*
or use the command line:
dfu-util -v -d 0483:df11 -c 1 -i 0 -a 0 -D bl_revolution.bin -s 0x08000000
*for some unknown reason Full Chip Erase does not work with F4 targets in the *Flight Configurator.
