Easy Installer Error downloading or writing image


I’m trying to build an image for a Colibri iMX7D 1GB following this guide.
I’m working from Windows10 on a virtual machine running Ubuntu 18.04 (Virtualbox).

I then transfer the oe-core/build/deploy/images/colibri-imx7-emmc folder on an USB drive and use it to flash the image on the board via Toradex Easy Installer (v 2.0b7).

I’m experiencing 3 issues:

  • sometimes the image on the drive is not listed at all in the available images in Toradex Easy Installer
  • sometimes an image is found but is listed as not compatible with the module
  • even when the image is listed and compatible, I try to install it but the following error message is shown:

Error downloading or writing image

xz: (stdin): File format not recognized

tar: This does not look like a tar archive

tar: Exiting with failure status due to previous errors

Can you please tell me what I’m doing wrong?

Thank you

Thank you Alex, it worked.


If build completed successfully you should get a tar file which contains Toradex Easy Installer compatible image. For example: Colibri-iMX7-eMMC_Reference-Minimal-Image-Tezi_5.2.0+build.7.tar Please check for details here.

Then you need to untar that file to USB drive. And use it to flash Colibri module.
