Are the other patches working?
Other recipes from the layer are being built OK
Could you share all the changes you have done?
Basically I made the changes needed to detect the EC20 Quectel device (following this PDF guide, part 3.2) from the sources of kernel in branch linux-toradex-4.9-2.3.x-imx as we are using the bsp 2.8b6. This is the patch content:

What exactly do you want to do? Why do you want to change angstrom-lxde-image.bb?
Basically what I want is to use the EC20 module from Quectel I have to use it as a GNSS module, in order to do that I found this repo containing the recipe to add the EC25 module to a yocto based project, and made a similar patch but based on the EC20, the rest is all the same.
I added a modified recipe to a layer I made that contains other recipes from other projects like gpsd.
I don’t care which toradex image I use at the moment, it was just an example to test the build. In a project I found, which had many useful recipes, they modify console-tdx-image.bb and add their recipes after the IMAGE_INSTALL += " \ … and I thought that I should add my patch there with them.
Is this the right way to do it?
