6. Start the “Betaflig ht ” configurator on the PC ;
7. Press and hold the “BO O T” on the F C, con nect the F C to the PC, then the FC is conn ected in the “DFU ” mo de, then you can flash the firm ware;
8.For the firmware flashi ng, you can choose to load th e firmware online or local(L ocal is recommended, it
needs to download in adva nce in Betaflight webs ite)
1.Start the Zadig softw are tool;
2.Press and hold the “B OOT” on the FC, connec t the FC to the P C.
3.Click “Options”,a nd select “List All Device s”.
4.Then select “S TM3 2 BOOT LOAD E R”,The n click “Replace Driver ”
5. Close the Zadig softwar e tool when replace succe ssfully,
Then disconne ct the F C from the PC.
(Notice:If you've run the above steps before, then you don' t need to repeat, starting directly from the 6t h step)
