Pine A64+ 2GB can´t boot

[elTorres]

Hi,

I bought this board at the beginning from kickstarter, but I can´t find time to test it until now.

The problem is that the board can´t boot (I test with Android and linux) and if I connect to the serial console using PINE64 USB SERIAL CONSOLE/PROGRAMMER I get this:

Code:

HELLO! BOOT0 is starting!
boot0 commit : 8
boot0 version : 4.0.0
set pll start
set pll end
rtc[0] value = 0x00000000
rtc[1] value = 0x00000000
rtc[2] value = 0x00000000
rtc[3] value = 0x00000000
rtc[4] value = 0x00000000
rtc[5] value = 0x00000000
DRAM driver version: V1.0
DRAM Type = 3 (2:DDR2,3:DDR3,6:LPDDR2,7:LPDDR3)
DRAM clk = 552 MHz
DRAM zq value: 003b3bbb
rsb_send_initseq: rsb clk 400Khz -> 3Mhz
PMU: AXP81X
ddr voltage = 1500 mv
DRAM DQS gate training error
DRAM init error!
initializing SDRAM Fail.

¿It's a hardware problem o can I solve it?

I have an open ticket in support platform, but I have not any respone.

Thanks in advance,
Fernando
