eMMC flashing an ubuntu image?

Been browsing the forums looking for information for my shiny new Le Potato.
I believe this is the one that includes the mali GPU binaries so that I'll be able to use hardware acceleration. I'm not certain tho, haven't been able to put it all together.

When I go to load the image with the USB_Burning_Tool, it complains that Parse burning image fail, and doesn't work. I assume then that the ubuntu image I downloaded cannot be flashed to the eMMC directly?

If my assumption is correct, how do I flash the image onto the eMMC card?

    Why this isn't included in the README.php file within the image directory, I do not know.
    But here is a how to: Link

    Ah, I must've missed this, thanks! That was a bit awkward, but not impossible. I wish they had a git repo I could PR into, I'd happily update some of their documentation as I go along.

    Welp, things don't seem to be working very well. The EMMC flash always fails after the partition table. I've even tried zeroing out the device first.

    I guess this means my MMC card is bad? and I should return it?

    There's a bug with the eMMC driver that was recently fixed. We haven't pushed the code yet.

    Ah, good to know, I can cancel my return then and hang on to the emmc card.
