Hi @koan !
The device tree adaptation process is described in How to Modify a Toradex Easy Installer Image | Toradex Developer Center, as you already know. The process described there didn’t work for you?
To do so, one would need the source code of the Toradex Easy Installer application, but it is not publicly available.
We have the meta-toradex-tezi publicly available, but it will not allow you to build Toradex Easy Installer for the same reason as above.
Could you please elaborate on this necessity? We have already newer Toradex Easy Installer versions than 1.8 available for Colibri iMX6ULL. Please refer to Loading Toradex Easy Installer | Toradex Developer Center.
Best regards,
