Hi @daniel_m.tx ,

I did some test. Unfortunately, didn’t solve. Please, check the result below:

1. Test

  • In local.conf has the MACHINE ?= "colibri-imx6ull".
  • I copy the colibri-imx6ull.inc file to my layer, layers/meta-custom/conf/machine/include/colibri-imx6ull.inc and update the TORADEX_PRODUCT_IDS variable to my-custom-devicetree-file.dtb.
  • Also, I changed the BBFILE_PRIORITY_meta-custom = "99" inside the layer.conf.
  • And run the commands
$ bitbake -c cleansstate tdx-reference-multimedia-image
$ bitbake -f tdx-reference-multimedia-image
  • Result: It Didn’t work. After build, the image.json still with the Toradex’s device tree file.

2. Test

  • I copied the colibri-imx6ull.conf file to my layer.

  • and run the commands to clean the state and build again the tdx-reference-multimedia-image recipes.

  • Result: It Didn’t work. After build, the image.json still with the Toradex’s device tree file.

3. Test

Following these instructions,

  • I copied the colibri-imx6ull.conf file to my layer.
  • I created my own MACHINE my-colibri-imx6ull.conf. Inside the my-colibri-imx6ull.conf has just:
require conf/machine/colibri-imx6ull.conf
  • Changed the file name from 'colibri-imx6ull.inc to my-colibri-imx6ull.inc.
  • Updated the local.conf to MACHINE ?= "my-colibri-imx6ull".
  • I remove the build/tmp and sstate-cache folders

My layer structure is:

├── conf
│   ├── layer.conf
│   └── machine
│       ├── colibri-imx6ull.conf
│       ├── colibri-imx6ull-extra.conf

But I got the errors:

Whether, inside the colibri-imx6ull.conf, I modified the MACHINEOVERRIDES =. "my-colibri-imx6ull:", I still got those errors.

Do you have another suggestion? Thanks!
