The OpenPilot bootloader code also allows the remaining section of flash to be reconfigured and re-flashed by the
OpenPilot Ground Station (GCS) via USB without requiring a USB to uart adapter.
# Restoring OpenPilot bootloader
If you have a JLink debugger, you can use JLinkExe to flash the open pilot bootloader.
1. Run JLinkExe `/Applications/SEGGER/JLink/JLinkExe`
2. `device STM32F103CB`
3. `r`
4. `h`
5. `loadbin opbl.bin, 0x08000000`
6. `q`
7. Re-plug CC3D.
Here's an example session:
