Issue on Firmware Update and Cyton Working

RaghulRaghul Vellore, Tamilnadu, India
in Cyton

I am working with 4 Cyton boards, each dedicated to acquiring separate EEG signals. Initially, all 4 boards were functioning correctly; however, they suddenly started producing noisy signals during signal acquisition. As a result, a firmware update was performed, but following the update, the boards are no longer connecting properly.
Among the 4 Cyton boards, one board's LED is blinking continuously and only responds when both the PROG and RST buttons are pressed simultaneously. Another board powers on normally and the dongle is recognized by the PC the Device Manager successfully detects it and assigns a COM port but the Cyton board fails to establish a connection with the dongle. When attempting to start a session in the OpenBCI software, an error message appears stating "Hardware is not connected, please check the power supply." This issue was reproduced on both older and newer versions of the OpenBCI software.
It appears that the firmware update has caused these issues. Kindly suggest a solution to resolve this.

    Hi Raghul,

    For this complex issue, you need to open a ticket with Customer Support. Send an email to (contact at openbci.com) and you can link to this Forum post. Firmware updates can be detailed and multi-step, depending on which set of firmware you started with. There are separate firmwares for the dongle RFduino, the mainboard RFduino, and the mainboard PIC32.
