Cyton board not working, dead firmware?

Hi,

I just received my Cyton board and hooked it up to the battery pack and made sure the voltage across it's ends is 6.5v

Yet when turning the switch to PC no blue light appears and it doesn't seem to be working,

I have the dongle connected and it's showing a blue light and the drivers installed,

The voltages measured across AVDD and AGND is 2.5v, and DVDD and GND is 3.29v

Any idea what might be wrong and what can I do to fix it?

Regards,
John

    OK, I believe this a serious quality issue, the board had no firmware installed, I reinstalled the firmware and it now works, but this shouldn't happen, as mentioned on the store the board should come with the firmware installed

    John, thanks for reporting this.

    Mentioning @openbci and Joel @biomurph.

    Can you please also send a note with a link to this thread to contact at openbci.com, and post back here what was said? Maybe it's possible during certain shipping situations with strong x-rays or other scanners, to corrupt the firmware.

    Regards,

    William

    @compujohnny ; Were you able to get the system to work after you installed the firmware?
    You are right. This should not have happened. We apologize and if there is anything we need to do to make sure your system is up and working we will be happy to oblige.

    Yes, I connected the electrodes to myself and got a signal on Bioera, thanks

    @compujohnny How do you upload the firmware to the cyton board if it wasn't giving a blue led and it wasn't working? I am having the same problem

    JDavid, hi.

    Are you saying you just received a new board, and it is not working? If this is the case please email contact at openbci.com, and explain your situation.

    Mentioning @openbci.

    Hi,


    You need to have the Arduino IDE installed and then follow the instructions here to add the OpenBCI board to the Board Manager list http://chipkit.net/wiki/index.php?title=ChipKIT_core#1.29_Auto_install_via_URL_from_within_Arduino_IDE_.28latest_version_chipKIT-core_v1.3.1.29

    Then you can follow the instructions in the first URL

    At first I thought the board was damaged but when I followed the steps to in the section "Put Cyton in Bootloaded Mode" and saw the blue light I thought it may be a firmware issue and I uploaded the firmware sketch the board started working

    Please note that it may not work the first time you try it as the dongle connection to the board sometimes disconnects or has errors sending data or some other reason, because mine failed to upload the firmware a few times and then it succeeded

    If that happens you will see the firmware being uploaded then midway it will stop the progress and report an error, just follow the whole process again and try putting the board very close to the dongle to make sure the connection is strong

    To clarify another point,
    After pasting the url from chipkit under  File->Preferences in
    "Additional Boards Manager URLs", You have to click on the Boards
    Manager and wait for the list to populate, then scroll down to chipkit,
    choose version 1.3.1 and install it, then from the Boards List choose
    OpenBCI 32
