How do you flash Ubuntu to eMMC on Linux?
I've just received a ROC-RK3328-CC
I'd like to flash the Ubuntu 16.04 image to eMMC using a Linux server
According to the manual page here;
http://roc-rk3328-cc.readthedocs.io/en/latest/flash_emmc_linux.html
If I want to flash the raw image, I must use the rkdeveloptool
Thus, I've cloned the Git repo, and successfully built the rkdeveloptool tool.
Now... where to find the raw image.... Hmmmm, the Getting started page [1] contains a link to a raw image [2], but the link is broken (leads to a "page not found").
Does anyone have a link to the raw image file for the Ubuntu 16.04 image?
Or better yet, Ubuntu 18.04, since it's now released and generally available?

Answering my own question.
Rather than trying to find a pre-built image, I built my own.
Thanks to Armbian community members bholland & gspillman for the inspiration. I found the information in this Armbian forum thread extremely helpful.
It looks like that information was probably instrumental in the construction of this Firefly page, but there are a number of typos and omissions on that page.
In any event, I now have a custom kernel, and a custom Ubuntu-based image built and it's working well.
Did you test the hardware acceleration with your custom image (I'd be interested in x265 codec decoding...)? If not, would you be so kind to test it?
just try to play a video from https://x265.com/hevc-video-files/ or any other x265 video and tell me, if it actually plays without any visual lags/stuttering and how much of the cpu is used doing this,thanks
@TieKei I tried playing one of the videos you linked on my image. The performance is very bad (lots of lags/stuttering). So it would seem the kernel source from which I did a build does not include the hardware acceleration.

Try this https://github.com/armbian/config It can be added to any Debian based OS. In menu launch Armbian config/security and settings/instal to USB EMMC. It moves the installation from SD to EMMC or USB. It's built in in Armbian. I'm booting a 250 gig SATA in USB 3.0 dock/hub. I love it!
