RC5 Update


I've followed the instructions listed for the cockpit update to RC5 located here: https://github.com/OpenROV/openrov-software/releases/tag/v2.5.1-rc5%2Bb95 . After I upgrade the firmware, I power it down, and remove the SD card from the BBB. When I power it back on, it seems to have reverted back to the old cockpit. Do I need to leave the SD card in permanently for the upgrade to take effect? or am I doing something wrong here.
