BeagleBone Black


#1

I am getting a new BeagleBone Black for my ROV am I able to use a factory one or does it have to be loaded with the open ROV BeagleBone Image


#2

You can use a factory one just fine. There are images you can download that will flash the appropriate software.


#3

This guide will walk you through the process to flash our software onto your BBB.

hi thanks for you replies

I have tried numerous times to to put it onto a SD Card but i seem to be having trouble within the terminal. I think I’m doing it right as per the instructions but i end up with invalid argument so i am not sure if it has been done correctly
Because this frustrated me i ordered another BBB from OpenROV which is not cheap because it is shipped to Australia.
It just turned up today so i plug it in and it seems as though it has not been flashed with the image this was the whole reason of me purchasing it

this is what comes up on the terminal after i have completed all the steps can you please tell me where i am going wrong

So disk4 is a 8gb micro SD card?

Can you do ‘ls /dev’ and see if there is a rdisk4. Perhaps a version of the os makes a difference on the use of rdisk vs disk. You can always use disk, it is just slower…

Also it appears the micro SD card is formatted with HFS already. You might try using the disk manager to reformat the entire micro SD card as fat to see if that makes a difference.

It is my understanding that beaglebones ship pre-flashed as well. Open a ticket with support if that was not the case. What syptoms are you seeing on the new bbb? Are you not getting the Cylon light pattern on the blue leds?
