Pine A64+ 2GB can´t boot
#1
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?
Come have a chat in the Pine IRC channel >>

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Edit: the debian image you've used is very outdated.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
You can find me on IRC, Discord and Twitter

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.
