I recently purchased the Overo EVM pack. The Chestnut43 included with it does not appear to be functioning properly. When I plug in the console port, the LED does not light, although the host computer does recognize the serial converter. When power is applied, there is no activity over the console (the Fire LED does light). Additionally, the RJ45 LED does not light even when connected, and the included LCD goes all white and stays that way regardless of how long power remains on.
I also have a Water and a Tobi, and I can make this setup behave properly (console LED, data over the console, full boot with networking, etc). I can also put the Fire into the Tobi and have everything work properly. It doesn't matter which COM I have in the Chestnut, it won't function.
Is there something obvious I should look for, or should I start the return process?
