 ### 2. Flashing the OpenMV Firmware
 
 Connect the Portenta to your computer via the USB-C cable if you haven't done so yet. Make sure you first update the bootloader to the latest version using the **PortentaH7_updateBootloader** sketch in the examples menu in the Arduino IDE.

 ***In bootloader versions 17 and older there was a bug that could put the Portenta in a boot loop when the transmission aborted while flashing a large firmware file. This was fixed in the bootloader version 18. We strongly advise to update the bootloader before you proceed with the next step of this tutorial!***
