About

I support OpenStack and Linux servers 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) and I’ve been in the IT industry since 1997. I have experience of lots of hardware, operating systems & other software, and I’ve held RHCE, MCP’s & Citrix CCA at various stages in my career.

  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.
