Oscilloscope action

Right, since it looks like subverting the firmware upgrade is going to require work to crack or circumvent the encryption maybe there's an easier way in.

Perhaps a serial console, for testing purposes, is just waiting to be found on the Barracuda board?


First, those pins on the headers which have obvious uses (power, display, keypad, usb etc.) were identified. Then, the rest of the pins, including the test points on the back of the board, were monitored with an oscilloscope during startup in the hopes of identifying something that looked like the Tx line of a UART. Nothing. Back to the drawing board.
