Fixing/salvaging dead control board/BB

[harrison]

Hi Matt,

1. I have never heard of a control board fail in that manner. Does it still happen if you disconnect the Beaglebone itself from the control PCB? I.e. just a bare, standard beaglebone sitting alone ont he desk?
If I were to guess the cause it might be that somehow the beaglebone’s internal power regulators got shorted, since some of these are used on the control PCB, but not sure how this could happen if as you say there was no liquid in contact.

2. Have you flashed the old beaglebone with the current version of the Chi.Bio operating system? This will update the underlying linux distro as well, which might solve this. I am unclear on what you mean w.r.t the specific board type: the Chi.Bio should be using a Beaglebone BLACK. Are you saying that you were shipped a Beaglebone GREEN? can you send me a picture of the board you _were_ sent?

The control board is designed for Beaglebone Black Rev C. I do not know whether it will work with other versions of Beaglebone Black, nor do I know whether it would work with beaglebone Green.
As to the pins – if they are going into the sockets as intended then it should be OK.

Hey Harrison,

thanks for the prompt response

1. Without the control board, there are still no lights when connected via micro-usb. It seems like one way or another it got shorted so not much we can do at this point.

2. Yes the old board has been flashed with the new OS. I assumed the chi bio boards were green based off the serial numbers printed on the side (same info/serial from EEPROM). Specifically, all the chi bio boards have BBBG in their serial, which from a quick internet search (when i first posted) was associated with the green beagleboard, although I just had a look at this a found one BBB black rev C listing that pictured a board with a BBBG serial so I’m probably wrong on this. Here are the serials:

OLD BOARD: 2315BBBK0187, CHI BIO BOARD: 000C1936BBBG0103

Here’s a pic of the chi bio BB (removed control PCB):

Well seems like the image didn’t render properly (at least on my end). Here’s the drive link:
