Olinuxino WiFi + TS LCD

SlyCom · April 11, 2013, 01:25:19 PM

Hi,

I'm new user of the Olinuxino. I've recently bought the Olinuxino Wifi with TS LCD.
I read that the board comes with build Android image. I connected the board to 7V (2A) power supply and the screen is black, the board is working I think as led is lighting.

Do I need to change something/somewhere to start working the board with screen?

Best regards

Hey SlyCom,

The board comes with image suitable for VGA screen. You need to upload the Android image suitable for 7'' display. Instructions and download location might be found here: https://www.olimex.com/wiki/A13-OLinuXino under "Using an operating system - Nand flash". You might want to browse/search the forums for more information - there is plenty of it on the subject.

Best regards,
Lub/OLIMEX

Hi,
Could you point me where is the android image for olinuxino wifi +LCD7ts. I can see only Linux images (Debian, Ubuntu Linaro) thank you.
Guillermo

Which image is correct for 7 inch lcd? 800x480 ?

SlyCom · May 30, 2013, 11:57:56 PM

Please help me with the board.
I uploaded both 800x600 and 800x480. I can see only something like backlight but nothing happen.

SlyCom · June 03, 2013, 05:04:18 PM

Any ideas? Broken board or LCD?

olimex · June 03, 2013, 05:21:54 PM

can you connect VGA to the board so you see if your power supply is OK at least?
board comes with Android preloaded for VGA, connect VGA monitor to the board, apply power supply and wait few minutes until Android make it first boot and buffer initializations

SlyCom · June 03, 2013, 05:52:52 PM

Is it possible to check the board (debug) via serial port and Telnet?

olimex · June 03, 2013, 11:52:38 PM

if you have USB-SERIAL-F cable you can connect and see the boot console messages

SlyCom · June 04, 2013, 01:03:55 AM

Hi,

I connected to the serial port and got a debug information. it's looks like the board is working but no LCD. Below is the log:

Any ideas? Its very important to run the LCD.

That is similar to mine except:
1. mine goes on past where your posted - does yours end there?
2. I use VGA

Please connect VGA device and report what it does.

Hey SlyCom,

Is it possible to power the board only from the USB and test if the board works with an VGA monitor this might shed some light on the source of the problem? Or at least again power the board only from the USB and see the boot log. Use the VGA image for the VGA monitor test.

It might be also a problem with the small connector of the 7'' display, check if the cable is straight and firmly attached to the plastic.

7V @ 2A supply should be more than sufficient to power the display.

800x480 is the native resolution of the display.

Best regards,
Lub/OLIMEX

SlyCom · June 04, 2013, 01:15:53 PM

Thank you for reply,

I will try VGA. I'm using regulated power source so I can set the proper power. I set the voltage to 12V and the power consumption is around 250mA. I checked the connector several times but with no results.

You wrote 2A. Its mean that there is something wrong with the LCD panel as main board + LCD consumes around 250mA.

SlyCom · June 10, 2013, 04:13:42 PM

Hi,

I connected the board to VGA. It works but when I connect the 40-pin cable to the board then the VGA can not be displayed.
Does the cable is ok, I use standard 40-pin IDE cable as board <-> LCD (board) ??

SlyCom · June 12, 2013, 02:32:52 PM

It seems that my LCD panel is not working. Is there any solution how to test the LCD? Otherwise I have to return my board and the LCD to the distributor.
