Christmas pine64 2GB - DOA - sendonline@yahoo.com - 12-28-2016
Greetings all,
My brother gave me a pine64+ 2GB model for Christmas and I believe it's DOA.
Let me first start off that my power supplies certainly meet the requirements of this board with 2amp, 2.5 amp, and yes, I borrowed a 4.0 amp from my ws2812 strings to try. The voltages are tight to usb 5v specs.
I'm a long time user of Pi boards. All of the aforementioned power supplies work fine with my Raspberry Pis and so do the sdcards I've tried with the Pine.
I'm also a long time user of linux and consider myself advanced in the OS. I use "dd" to dump and read often for other systems. Every image I've dumped for the pine is fine. Some of the images I've tried create a fat for /boot, others have /boot in rootfs.
I tried several images and never got a thing, until I decided to hook up the debug port to a ttl adapter and this is what I got:

It appears the RAM is bad and never attempts to access the card which explains why none of the imaging I've done ever worked.
I submitted a ticket to them (overdue), but at this point I don't think I'll get a response. I sure hope they can do something. My brother, who doesn't have money waist and is disappointed as well.
This is my experienced thus far.
