Damn, looks like I too, joined the club of people with broken DRAM.
Booting on SPI: rk2aw + U-Boot's TPL on secondary:
Booting from TowBoot on SD Card:
SPI rk2aw + Rockchip's ddrbin on Primary:
Damn.
So, yes. I've joined the club of people seeing that.
Given that it's complaining of not being able to initialize a RAM channel, I'm starting to suspect that "managing to fix it" involves either a chip reflow workstation (for the DIY solution) (Which is way beyond my reach) or a main board replacement (which is expensive).

So, yes. I've joined the club of people seeing that.
