CT stays in red LED

Hi all,

recently I have purchased a Cubietruck. After the initial setup, according to this manual:

http://docs.cubieboard.org/tutorials/cb3/start

the CT stays in red LED. The proccess to install the OS ended succesfully (with Ubuntu 13.10)

I have plugged in with several ac adapterss (ipad, iphone adapters, with 5V and 1-2A), but I have no results. There isn't any HDD or uSD card inserted... I am so confused with this, could be a hardware problem?

Thanks!

Hey,

are you talking about the red led near the power connector or one of the four multi-colored leds near the SD-card slot?

You can disable the four led bank. But afaik the single red led is the simply a power indicator and will always be lighted as soon as the CT is powered on.

Do you get any output on screen or are you able to connect via ssh?

Hi neo9,

thanks for your quickly response... About your question, yes, is the red LED between the power connector and ethernet RJ45. I have just retry to reinstall the OS through the same method, but I have not response, only the red LED powered on. The method ended succesfully again.
I plugged in through HDMI, but the CT  hasn't any output (on a TV).

I don't know if it could be an hardware issue... I will try to contact with the vendor.

Update: I have seen in this post the same problem:

Thanks again,

Mhm, so ONLY the red LED? Doesn't sound good then.  :-\

Normally after a clean boot the four other LEDs should be making quite some disco on the other side of the board.

Any chance you can test with another monitor, like a "normal" pc lcd screen, only to make sure?

Do you have an microSD card at hand? That way you could test the board with a card image, not using the nand.

EDIT: Another question: Do you use the "re-format nand option" when flashing an image? (You should).

Yes, I have a 4GB microSD now... How can I test the board with the card image? Could be the following manual?

http://docs.cubieboard.org/tutorials/ct1/installation/install_lubuntu_desktop_server_to_sd_card

Any additional help/link/manual? Thanks again, it's my Christmas present...

About re-format nand option...When I enter in FEL mode, I click on yes to format the device...I use LiveSuit to do this.

Use a ready to copy sdcard image. The image contains bootsektor as well as all partitons and filesystems.
Just write the image to the SDCard like burning an iso-image to a CD.

Images can be found here  http://cubieboard.cmabreu.com.br or elsware in this forum.

Yep, the instructions from that link should work. Read this too: http://linux-sunxi.org/Bootable_SD_card
There is a lot of other good stuff on http://linux-sunxi.org/Main_Page you might want to read that too if you are new to the CT.  ;)

EDIT: Using a Pre-Made, Ready-to-Flash card image, as rose suggested is a very good idea and maybe easier.

Thanks guys! While I download the images, I will try to reinstall the preloaded Android OS, as an additional test. I will update the thread with the results.
Again, thanks for your responses.

Hi all,

finally I have obtained the boot log from a serial connection. I have attached it. First of them is a boot log from NAND flash, and second one is boot log from uSD card.
Both stop to log in serial console when it starts to load kernel... I have searched about this but I can't get too much information. Today I will install again other OS (Android, Fedora or Lubuntu), if I get any result I will update the post.
Could be a bad write in nand/sd card? How can I get a log from OS when it's booting? Any experience about this issue?

Thanks again!

Regarding to your attached logs I doubt that your OS booted.
There are two possibilities.Either you are using unsupported image or your NAND is damaged. Try to flash lubuntu-server image.
