Tips, Tricks and Guides / Re: Cubian Video Kiosk with Mplayer on CB2
« on: December 01, 2013, 04:22:46 pm »
I got some time to try this out and I'm not getting it to work. I'm trying this on a CB1 and using the latest Cubian release. What's odd at this point is that when I try to debug what is going on I can no longer issue a sudo command. It comes back and says

cubie is not in the sudoers file
. I can ssh in with cubie/cubie but can't do any sudo commands.

For reference here's some info:

Code: [Select]
cubie@Cubian:~$ sudo nano /etc/modules

I do get the login menu on the HDMI monitor but it doesn't let me log in with cubie/cubie. Perhaps this has something to do with the slim modification?

Could you perhaps make a SD or NAND image of your setup so we can test it easily?

Just solder a wire across D2, I made a good picture of it here, http://www.iotllc.com/joomla/media/kunena/attachments/901/Cubie_D2.png. There are hundreds of people doing this and with a short little wire on the Cubie it is easier to handle than if you have a 4-pin power connector soldered on the bottom of the board. By using the 4-pin power connector you then also have to match the height of this connector to the other GPIO pin headers.

Is there a reason why your images aren't posted on the CubieForum server?

If you click on the picture in that link it will open up a full view of the picture which shows the location of D2 with a white wire soldered across the diode to short it.

Sorry for the late reply, I missed this post.

Beginners / Re: How to connect touch screen to Cuieboard
« on: April 13, 2013, 05:50:57 pm »
  • You're going to need to know the specifics of the LCD panel so you can configure the FEX file for the proper timings.
  • You're also going to require additional power supply rails since there's a good chance you'll need 3.3V for the LCD and 12V for the backlight.
  • Looks like that panel is using a 4-wire resistive touch screen which could be directly connected to the A10 touch screen controller
  • The harder part is going to convert the FFC cable to something that you can attach to the Cubie. There are some FFC-to-Pin Header adapter boards available on the internet but they can be expensive.

Most of what you need to connect LCD panels to the Cubie can be made using my Baseboard if that's of any interest to you.

I confirmed that one of my boards had a dead crystal which is used for the network chip. IF you have access to a scope and soldering tools you can check and replace the crystal if needed.

Cubieboard v1 Hardware (A10 Based) / Re: LCD/Touchscreen
« on: April 03, 2013, 10:04:45 pm »
I've got 15.6" screens and touch screens on my site for sale. I used this model LCD and touch screen for all of the initial testing when bringing up my baseboard. If you're looking for that size you can get everything you need to make a nice little system.

I see cubiebase board use lcd1 HS/VS
I think not work for vga
!!?https://store.iotllc.com

My baseboard was designed before the problem was found on the Wiki for the connection. A simple modification on the intial boards allowed the VGA to work. This has been changed  in the design now.

Introduce yourself / Re: Introductions

George from sunny California here. I've been into electronics for as long as I can remember. When I first started in the corporate world it was with a semiconductor company and the first parts we produced at the Roseville factory were 4k DRAM (you know, the parts before even memory modules came along). I grew up on memory and as the industry changed I was heavily involved working directly with the major OEMs on the first memory modules (think NeXt, IBM with a dual zip SDRAM module, SGI with a stacked module). It was very good to travel around the world and interface with all the different companies and cultures.

I left the corporate world about 10 years ago and have been doing my own product designs and contract work for other companies. I'm mostly a 1 man show so I often need to dig into software on all levels to go along with debugging hardware. I produce boards as well as complete products so between that and my family my days are pretty full.

Cubieboard v1 Images (A10 Based) / Re: Ubuntu 12.04 LTS + Lima400

Is the Lima400 driver working for general video decoding or do you have to compile your "video player" specifically for Lima400 usage?

Sorry, is this a question? I'm confused what you are trying to do.

Cubieboard v1 Hardware (A10 Based) / Re: hardware clock for the Cubieboard
« on: February 25, 2013, 08:28:40 pm »
Yes, I think my next revision of the baseboard will include a RTC chip with battery backup. Tom had mentioned a while ago that their next version of the Cubie board would include I2S output but I haven't seen any possible dates for that change. I would like to make my baseboard changes support any changes that Tom is planning on making.

Cubieboard v1 Hardware (A10 Based) / Re: Dual LVDS support

I've only used Linaro (both ALIP and Desktop). If I recall correctly this also worked for Android too.

Not directly since the 2nd LVDS port is used for other connections but I have run both HDMI and LVDS at the same time
