About

I work in tech support for a leading open source company. I first started experimenting with Linux in 1999 (a floppy initiated version of RedHat 6.5 purchased from PC World in Solihull – I still have the floppy disk with Tux on the label somewhere) and I’ve been in the IT industry since 1997. I have experience of lots of hardware, operating systems and other software, and I’ve held RHCE, MCP’s and Citrix CCA at various stages in my career.

This website is mostly about my escapades making Chromebooks capable of running Linux natively.

  1. I know this probably is not the best place to ask.. I have a stack of c300m’s (asus) that will not restore.. during recovery, i am getting an error :
    dd error writing ‘/dev/mmcblk0’ : Input/Output error

    then it proceeds to do a error scan forever..

    Is there any way to get a unit in this condition to boot a sd card (i believe its considered /dev/mmcblk1) rather than from what I assume is a failed emmc?

    Just seems odd to have soo many units failing with the same errors.

    (note: I know the recovery usb is working correctly, since I have used that same usb to recover about 6 other units)

    I tried getting assistance from asus.. I may as well consider these units spare parts with the support they don’t give.

    1. You could boot from a ChromiumOS USB (maybe that works with an SD card too, not sure) – https://www.chromium.org/chromium-os/quick-start-guide

      You can then either continue to use ChromiumOS, or write a new RW_LEGACY slot, and boot some form of Linux from an SD card – https://johnlewis.ie/custom-chromebook-firmware/rom-download/

      It doesn’t seem that odd to me – failure rates with cheap flash are pretty high, and they generally seem to go pretty close together. I remember MyDigital SSD NGFF SSD’s would generally go within 6 months (although they “said” it was fixed by a firmware update).

      You may have more luck going to Google to get support. I think OEM support is pretty bad at the best of times.

  2. Have you recently updated your supported models matrix? I ask as I see that my Acer R11 (cyan) is no longer listed as being suitable for a full ROM coreboot build. However, I have an Acer R11 which I have flashed using your firmware, and it is running GalliumOS without a hitch. I don’t miss the ChromeOS at all, and I run LibreOffice Impress and everything there works perfectly too. I am very pleased. Thank you.

    1. Nope. The R11 has never been able to take a full ROM. Perhaps you loaded somebody else’s attempt at a full ROM.

      It has, and will do RW_LEGACY though, which will allow you to use GalliumOS.

      You’re welcome.
