PINE64

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

Moin moin,

what image are you trying to boot? Are you using a power supply that can deliver 2.5A+ at 5V?

I tried android 6 from ayufan and Debian Base 3.10.65 BSP.

And yes, I use a power supply that can deliver 3.0A at 5V

Try the troubleshooting steps.

It will be easier to determine whats causing the issue.

Edit: the debian image you've used is very outdated. If you need debian then please try Armbians variant ... you can also use ubuntu base

I had review the troubleshootings steps with no luck:

Tried several Cards
Tried several images
Make the images from Windows and Linux
Test power supply
Deatach all but power supply and SD Card

I have seen that in the first versions of the board there were problems with the SDRAM, and it appear very similar as my problem (DRAM DQS gate training error), that is why I ask for others things that can cause that error .

I would be grateful if someone from Pine64 support would tell me how to proceed with a replacement board.
