Beginners / Re: Working with cheap China HDMI display
« Last post by rgmhtt on Today at 09:11:47 am »
Go to http://linux-sunxi.org and look up the various boards, and their uboot support state.  This will tell you which processor, graphic engine and the like for each product supported by sunxi uboot.

I have an old, rather cheap AOC monitor with VGA/DMI.  I use a DMI/HDMI connector and it works fine with my Cubieboard2 and Cubietruck HDMI.  Note that the Cubietruck VGA only kind of works.  This is a known limitation of its uboot.

I use Fedora and Centos as my distros.  I am a tester of both.

Beginners / Working with cheap China HDMI display

Dear colleagues!

Please, help with your HDMI experience.

I have a project with a plenty of small linux boards which must be connected to the cheap displays. I’d like to use these:

https://ru.aliexpress.com/item/Podofo-7-inch-LCD-Car-Monitor-Rearview-Screen-HDMI-VGA-DVD-Digital-Display-HD-Resolution-for/32788985703.html?spm=a2g0s.9042311.0.0.366833edyaa86f&aff_platform=aaf&cpt=1528348687239&aff_trace_key=e4fc4b8e1a624052ba5b93eac03716c5-1528348687239-01705-VnYZvQVf&terminal_id=6f98e3562e4f453c8baccee27367e3ab&dp=43b77dae0a3ae29c39e51463c1ea5190&af=139947&cv=47843&afref=http%3A%2F%2F4pda.ru%2Fforum%2Findex.php%3Fshowtopic%3D750921%26st%3D5240&mall_affr=pr3&aff_platform=aaf&cpt=1528365410096&sk=VnYZvQVf&aff_trace_key=84a6e5076bfc45e6a7fe76045d06fbb0-1528365410096-08679-VnYZvQVf&terminal_id=6f98e3562e4f453c8baccee27367e3ab

This display works via HDMI with Raspberry but refuse to works with Orange Pi PC plus.  As I can understand it is same issue described there

https://www.cnx-software.com/2017/09/15/7-lcd-display-with-hdmi-input-audio-output-launched-for-orange-pi-boards/#comment-546014

My only need from linux board : eMMC (or NAND) memory (SD card is not reliable) and cooperation with such displays. Raspberry can work but does not have eMMC chip.

What do u think , can I use one of Cubieboards in my application? Does it have same HDMI interface with Orange Pi or completely another?
 
Thanks!

What would I specify on ebay to get some more power cables.

This USB to 4mm cable is really handy.  I have been using them for other things and now I need a few more...

thanks

General Discussion / Re: Centos 7 for Cubieboard 2 and 3 (Truck)

A couple of updates.

First the uboots rpm is  uboot-images-armv7

And since my server is a Cubieboard2 with this rpm installed, it was easy to make a symlink to the directory or all the uboot files and update the page to the uboot location:

http://www.htt-consult.com/uboot

So this should simplify matters.  Note that the uboot for the Cubietruck Plus is NOT the one you want.  I will update this once they get things simplified for the Plus.

I have finally updated my Centos 7 howto:

http://www.htt-consult.com/Centos7-armv7.html

It is really easy now to get Centos7 up and running.  You have an image choice of server, Gnome, or KDE (EPEL issues with Xfce still).

Caveat is you need a system where you can install uboot-tools to get the right uboot file.  For me it is easy on my Fedora notebook.  If your desktop does not provide uboot-tools, you can always first install Fedora28-arm:

https://arm.fedoraproject.org/

Grab the uboot file and go to the Centos installation.

Or perhaps I can put the latest uboots on my server...  Hmmm.

Cubieboard 5 support in the works.  A few have it working.

I suspect Fedora works well with the latest kernel.

Fedora 28 (probably still 4.17.n) can be gotten from the production page:

https://arm.fedoraproject.org/

You can get Fedora 29 or Fedora Rawhide (30) which already has 4.18 from:

https://koji.fedoraproject.org/koji/tasks?state=all&view=tree&method=appliance&order=-id

I am currently testing F29-Xfce and minimal on Cubie2 as it has openSSL 1.1.1 beta.

There has been a thread on this over at the Centos7-arm SIG.

Go to: https://lists.centos.org/pipermail/arm-dev/2018-August/thread.html

And look at the "Cubieboard5 performance" thread I started.

I don't own a Cb5, but was looking into one.  Decided no due to that sata is via internal usb, but it started an effort to finally get the right uboot and kernel in place.

You may be able to use this kernel work for linaro.  Or switch to Centos7...
