a20-lime2 doesn't boot/work

[pcjackson06]

I just purchased the A20 Lime2 and have a 64gb MicroSD with Debian 3.4.90 release 2 (a20-lime2_debian_3.4.90_release_2.img) that I flashed in OS X El Capitan with the following command in terminal: "dd if=/pathtofile of=/dev/disk2 bs=1m).  The A20 is connected to power via a StarTech USB to Barrel Type M 5V connected to a 5V power adapter - I've tried a few.  The red PWR LED lights up and the ethernet lights come on.  I cannot get the HDMI connected display to show anything - both displays I've tried just go into power saving mode.  Any suggestions would be appreciated.  Banging head against wall.

1. Fake SD card?  Re-read and compare its image.

2. Use a debug lead for Lime's console tty to see how far it gets.

3. Sounds like your power is far too weak.
