SOPINE A64 DRAM init error - vicb - 05-29-2017

Hi!

I received the SOPINE A64 with motherboard. 
The problem is that the initializing SDRAM Fail
The log from serial console:


Code:
HELLO! BOOT0 is starting!
boot0 commit : 045061a8bb2580cb3fa02e301f52a015040c158f

set pll start
set pll end

rtc[5] value = 0x00000000
DRAM driver version: V1.1
rsb_send_initseq: rsb clk 400Khz -> 3Mhz
PMU: AXP81X
ddr voltage = 1500 mv
DRAM Type = 3 (2:DDR2,3:DDR3,6:LPDDR2,7:LPDDR3)
DRAM clk = 672 MHz
DRAM zq value: 003b3bbb
DRAM error status 0 
DRAM init error!
initializing SDRAM Fail.


It's a hardware problem or can I solve it?
Thank you!

Mod edit: wrapped terminal output in code tags - heaps with long code, and also prevents 'smilies' randomly popping up

Looking like you run the PINE A64 OS build on SoPine module. The SDRAM fail is due to SoPine using LPDDR3 system memory. Please uses the OS build that targets for SoPines and should able to boot up properly.
