Install Lubuntu to Plus 2E eMMC and pre-set resolution?

Galane · Published in 2016-12-7 10:59:49

I want to try Lubuntu on the eMMC of my Orange Pi Plus 2E, and pre-set the HDMI output to 1280x1024 to match a Dell DVI monitor. I have the Lubuntu_1404_For_OrangePi_Plus2E_v0_8_0.img a 16 gig class 10 micro SD and various PCs running Windows 10.

I have a HDMI to DVI/audio splitter box, but either it's not working with the video output the stock Android install is doing or the monitors I've tried don't support the 720p default from the O-Pi. I know that's the default from hooking it up to my big TV, but I don't want to use this in my living room.

I am still waiting on my Plus2Es on the mail, but I am also interested in your exact setup. I would like to run Lubuntu on them, connected to 1280x1024 (HP) DVI monitors. Having a look at /media/boot on one of my OPi-PCs running the Jacer image, I wander if it would be just a matter of editing script.bin say for the OPi-Plus, for example, as a starting point. Please share your findings on this.

Hi

I've got Orange Pi PC Plus. Successfully installed Lubuntu on the SD card. I tried to install Lubunto on eMMC. There are some instructions in the folder /home/orangepi/burn_to_emmc/readme.txt I followed instruction but the system not work. I can read some log via UART port. There are messages about a problem with image reading.

Have You got some good bootloader or some image of lubuntu to instali it on eMMC ?

Best

Note added after writing: all the information contained here is either in the forum or in links pointed from it, but it is scattered and somewhat difficult to put together. I hope this helps people save precious time. All credit goes to the many people who posted the original information in the first place.

Still waiting for the +2Es on the mail, but I finally got to do some tests with my OPi-PCs regarding the video resolution, and after some sweat I got them working with some of my (DVI) HP monitors. My test setup is:

OPi-PCs running Jacer Lubuntu (15.04), connected to HP monitors via DVI, with HDMI cables from the OPis hooked to cheap HDMI->DVI adapters from eBay or Aliexpress. The monitors I tested so far were 1280x1024 native resolution (60Hz). I will try another HP with 1440x900 as soon as I have a chance.

I first messed around with script.fex, but that was not enough. The kernel was not aware of other resolutions (via HDMI) besides the few 16:9 default ones and a couple others, so in as few words as possible this is what you need to get it working.

1) Edit script.fex as follows:
- in [clock] section, change pll_video to 432 (which is a multiple of 108.00). It is probably set to 297 (multiple of 148.50); (*)
- in [hdmi_para] section, add:
      - hdcp_enable = 0 (this is a potential point of trouble, better save yourself the trouble, disable HDCP);
      - hdmi_cts_compatibility = 1
- in [disp_init] section I made a few modifications, they may not all be necessary, but I do not have the time to strip them out one by one now just to find out. It is working as follows:
      - screen0_output_type = 3 (this is probably how it is at the moment, i.e., use HDMI)
      - screen0_output_mode = 5 (for 1280x1024. Use mode 4 for 1024x768, but I have not tested that) (*)
      - fb0_scaler_mode_enable = 1 (including this line and editing the next two may not be necessary)
      - fb0_width = 1280
      - fb0_height = 1024
2) Replace the default /media/boot/uImage with the one provided by dni here. Basically this image has modes 4 and 5 (720p50 and 720p60) replaced by the new ones (4:3 1024x768 and 5:4 1280x1024, respectively), or at least that's what I made from it. dni probably edited the timings in hdmi_core.c and perhaps modified some other files and recompiled the kernel. Any questions contact dni directly

And that's it! You should have Lubuntu 15.04 running in your 1280x1024 ( | 1024x768) monitor via DVI. Easy and painless.

(*) 1024x768 required pll_video = 260, if I am not mistakened.

Note: Armbian seems to have a whole bunch of video modes already setup, so if it's all the same to you, it could be interesting for a new install. If you have systems already set up and/or need Ubuntu for whatever reason you may have, the procedure described here should not take more than a few minutes.

Hello Everyone!

I did the same as wmisio, but it didn't work as well. The Lubuntu image for Opi+ 2E work perfectly on the SD card, but when I try to transfer to the EMMC nothing happens. The board appears don't turn on without the SD card. I also tried other Ubuntu images for ARMhf unsuccessfully, allways the network drivers don't work.

Does someone knows how to install a Ubuntu/Lubuntu image on Opi+ 2E's EMMC?

Thank you very much.

With Armbian everything works. Network, eMMC install, video decoding, ...
