Check GPIO2. It must be left floating so a pull-up can pull it high. The firmware supports two board types: tCam-Mini and tCam-Eth. It uses GPIO2 to select the board type. When it thinks it is running on tCam-Eth it will try to initialize the ethernet driver which will fail as you see if there is no ethernet. You want the firmware to think it is running on a tCam-Mini board.

You can look at the tCam-Mini schematics or the firmware/main/system_config.h file to see what the connections should be.
