Hallo,
dachte das ich mal ein kurzes Tutorial zur Erinnerung hier poste, falls jemand mal sein CC3D/Naze32 nicht wiederbeleben kann.
Gesucht und gefunden im Webarchive .. da Openpilot leider down ist :-(
Das ist der letzte Schritt den man machen kann wenn alle Versuche die BL Pads zu Brücken um den BL zu aktivieren, scheitern.
Bei mir wurde der BL durch BorisB Betaflight überschrieben und die gewohnten Methoden gingen nicht mehr.
-----------------------------------------------------------------------------------------------------------
Loading the Bootloader
Download the stlink V2 application from ST.com
Download the latest version of the bootloader for the CC3D. (as of release 14.10 Mini Me we're using CC3D Bootloader v4)
Pull the 2 jumpers off the F4 or F3 discovery board to enable external STLink mode on the Discovery board
Rig up a connector to the SWD port to connect GND, IO and CLK - those are pins 2, 3 and 4 of the CW2 port. The connector to the CC3D board is a JST-SH 1.0mm 4-pin cable. There are header pins available to make the connection to the SDC port on the Discovery board, as well. The connections are as follows:
CC3D STM32-Discovery-F4 STM32-Discovery-F3
(CN3 - SWD)
Pin 1 gnd Pin 3 - GND Pin 3
Pin 2 (nrst) n/c Pin 5 (optional)
Pin 3 (io) Pin 4 - SWDIO Pin 4
Pin 4 (clk) Pin 2 - SWCLK Pin 2
Launch STLink on your desktop.
Rig up a 5v power source for the CC3D and connect it to the discovery board. A current limited power supply is recommended.**
Connect the Discovery board to your computer using a usb cable.
Run STLink and hit the"connect" icon. It should come back with data.
Hit the "open file" icon, followed by the "program and verify" icon.
Your CC3D now has a fresh new Bootloader and the blue LED should now be lit after a reset.
Connect to GCS and perform a rescue firmware load.
**
On the Discovery-F4, 5V can be accessed at the top of the right set of DIP pins.
*NOTE on this image, ST-Link is Disabled!!
On the Discovery-F3, 5V can be accessed at the top of the right set of DIP pins.

Beim Neuflash braucht man nicht zwingend den BL, ging mir eher um die Reaktivierung meines CC3D, da man im STLink auch gewohnt bin/hex files flashen kann.
