Hey, it's been a few months and firstly apologies for the silence, however, I was able to get my hands on a 1.8v FTDI Serial Adaptor, and have been able to get some output from the device.

Sadly, unless I plug it into the computer and use the Kubrick Utility I don't get anything out on the serial monitor. But this is what I was able to get:

Code:
U-Boot 2009.08-lab126 (Feb 19 2012 - 05:03:11)

CPU:   Freescale i.MX50 family 1.1V at 800 MHz

Invalid board id!  Can't determine system type for RAM init.. bailing!

I'm not overly sure what this means for the potential of recovering my device, but hopefully it could shed some light on what's wrong!

Thanks!
