Using eMMC

  • @wappi That's only one dd command. Hardly worth integrating a tool that is just 1 line. Maybe in the future when there's more distros, we will add a tool for downloading and dding.

  • It was odd, I loaded the ubuntu 16.04 image to the SD, and I can probably do the same as the above with the different IMG files.

    The tricky part is the timing of plugging in power, and within 1~3 seconds snapping on the emmc module (this part of the process is kinda wonky).

    LibreElec is super snappy on the emmc module, I agree SD works pretty well period on this board as compared to the RPI2-3 models. However, my librarys are rather large (+400 videos) and with the setup right now, I haven't even needed any advanced settings for video playback. Its quite nice.

    The process in the write up should be much easier for standard ubuntu image transfer to the emmc module. As others had stated the desktop version for me had a no hdmi error, or some lockup, but the server headless version worked for me.

  • I agree with @loverpi the commands to make this work, was really only 3~4. Keep a backup sd with a standard ubuntu load if you ever need to edit the files.

    I will say, the ubuntu version I downloaded did not have the eth0 interface up or set for dhcp, and no nano to edit locally. That was actually more time-consuming than it took to DL (wget) extract (GZIP) the IMG, then zero out my EMMC (dd if=/dev/zero) only because it was pre-loaded with android.

    I can test this with a different img if you'd like @wappi , to confirm its reproduceable.

    I will say that the handling or perhaps using the uboot to define which media is used for boot (uboot button?) to make it easier to simply boot with both SD and EMMC plugged in.

    Rather than deal with the power on, then quickly plug emmc module fiasco.

    @deviat1 Can you try to dd Android image to eMMC and try to boot from? Interesting would also be Armbian from eMMC.
    @loverpi I do not need a tool for dd commands - just OS desktop images that work and boot from eMMC. I understood that boot.scr needs to be changed to boot from eMMC...
  • @deviat1 I used Armbian from SD and dd Libreelec to eMMC... really nice to have my eMMC in function again. Thanks.
    It always boots first from eMMC. Therefore I agree we need somehow a way to choose between. I am not sure about how often eMMC can be plugged in and out until connection is damaged.

  • @wappi glad to hear, its snappy, I'm happy with Libreelec on it. I am currently flashing the Android preview to tinker with and see if it boots.

  • Seems with the Android preview, I get no video output.
