Flashing Cyton with DefaultBoard "Program flash failed"
We have an electrode cap kit, and are having issues flashing an arduino sketch onto the Cyton board. We were able to successfully flash the Cyton board with the DefaultBoard example one time, but after making some changes to the DefaultBoard to add a button push event, we failed to flash the Cyton board. Now, all of our Arduino sketches seem to fail to flash. The error that comes up everytime we try to flash the board looks like this.
As of right now, the Cyton board LED doesn't turn on when the board is powered on, but the LED does flash when the board is put into boot loader mode.The BLE dongle does light up blue when plugged in, and while trying to upload the sketch, the dongle flashes a red light and a green light, but the sketch always fails with the above error message. If you could provide some guidance on how to troubleshoot this problem we would greatly appreciate it.
