Step By Step How To Install Ubuntu Image

[mkocsis]

Need some help.

I downloaded the image, with {code:bash}xzcat xenial-pine64-bspkernel-20160507-1.img.xz|sudo dd of=/dev/disk2s1 bs=1m{code} to flush to the sd card (32G) from my Mac. I have a raspberry pi microUSB power source (2Amp), and a HDMI cable. Pretty sure HDMI cable and SD card are working, as I basically pulled them off from my raspberry Pi.

And I think I finished the write, I have the output of:
0+59201 records in
0+59201 records out
3879731200 bytes transferred in 2984.895890 secs (1299788 bytes/sec)

Nothing happened except the red light was on after the power source was plugged in. No video output. Any ideas?

THANKS!

It seems dd didn't manage to write anything to your sd card, the numbers in red above should be the other way around. The first number indicates how many full blocks of data have been read or written, the second number shows the number of incomplete blocks. 

I don't know for certain how Macs assign device names but it seems you have used an existing partition on your sd card (dev/disk2s1) rather than the whole device (/dev/disk2s, excluding the 1 at the very end). Try using the entire command leaving out the final 1 in the device name.

Before dd'ing an image to a card I have a habit of wiping the card with fdisk to remove all partitions that might exist on the card. I don't know if it's necessary, it's probably not.

Looks like this is my problem as well. I've tried a few images and it's not working. I'll see what I can dig up. I guess I could try to find my old Windows laptop but needing Windows would be super disappointing.

Power -> Red Light only. Attached via power only cable from an Anker 5V 2.4A dedicated 60W power supply + HDMI-DVI to 1600x1200 Dell monitor.

EDIT: Probably actually a different problem - looks like my dd command was successful, but I'm getting the same symptoms.
