wandboard doesn't boot

[olli]

Hi we just got a Wandboard (i.MX6Q quad core I think, this model was ordered). I have tried to boot using different prebuilt SD card images including Arch Linux for Wandboard. Following the instructions here: http://archlinuxarm.org/platforms/armv7 ... /wandboard

Only U-Boot starts but the Linux kernel does not boot. Instead the board seems to restart indefinitely.

Similar behaviour for other Linux distros (e.g. Ubuntu 12.04 and 14.04 from wandboard.org and armhf.com). Only once or twice the kernel booted (after U-Boot had looped a number of times) but the board restarted at the kernel log message "Galcore version ..." which might be when the GPU is initialized.

I have tried with different SD cards, 4GB and 16GB. I think I tried with the "dual" core U-boot image as well but the board did not boot at all. One of images was using the SPL U-boot which should be able to detect the version of the i.MX6 CPU and other HW configurations.

The board is marked WB-EDM-i.MX6 REV C1.
I am using a 5V/3A power supply so I don't think lack of power or low voltage is a problem.

Is this board broken? Or just incompatible with all existing prebuilt images? http://www.wandboard.org/index.php/downloads mentions "not rev C1" in one place but I did not use that image.

Thx,

Tried with the Android Lollipop image (from http://www.wandboard.org/index.php/downloads), same problem. I am trying to understand how to get onto wandboard.org mailman list but the link provided there seems broken.

I tried with a different power supply and now the board boots cleanly! Tested with both Android Lollipop and Ubuntu Trusty images.
The non-working power supply was of the brand Actiontec. It was hardly ever used.
