Eliminating unwanted devices on Orin NX p3767?

[HowardE592]

I'm new to the Jetson and the guides to building images using this code are a godsend! Thank you all to those who figure this stuff out and share. I have an application which is using the p3767 module, and the support I find here includes the p3768 carrier board. So I'm using the machine "p3768-0000-p3767-0000" and I get an image that make the chip boot, but:

1. It insists on looking for the camera which we don't have and throws errors

2. It insists on offering the operator the option or pressing ESC to change boot device and such.

I created a new machine that is a copy of the p3768-0000-p3767-0000 file that has the include for the devkit removed, but it's still looking for peripherals that are probably part of the 3768 carrier. What I need is a configuration that simply supports the peripherals on the 3767 board along with the serial port for the console. If I had that I could build up to the devices we're adding to our own custom carrier.

I've seen the discussions pointed to by the Ridgerun page (https://www.ridgerun.com/post/yocto-for-nvidia-jetson-platforms) and a fun blog by Miru (https://www.miruml.com/blog/tutorial-building-a-yocto-image-for-nvidia-jetson). Is there another resource that talks in detail about customization?

Thank you in advance for any suggestions.

Welcome!

I've seen the discussions pointed to by the Ridgerun page (https://www.ridgerun.com/post/yocto-for-nvidia-jetson-platforms) and a fun blog by Miru (https://www.miruml.com/blog/tutorial-building-a-yocto-image-for-nvidia-jetson).

Those look to be largely about getting started - you may also look at https://github.com/OE4T/tegra-demo-distro for a turn-key example demo with necessary layers and some demo images/functionality.

Is there another resource that talks in detail about customization?

Your best bet is likely the wiki and discussions here, or you might be able to get some input in the matrix/gitter channel referenced from https://github.com/OE4T/meta-tegra/wiki. https://github.com/OE4T/meta-tegra/wiki/Creating-a-custom-MACHINE is one which is worth a look if you haven't looked at that one yet. There are also some relevant discussions about devicetree customizations which might be useful for you, and I suspect that's where you'll need to start to modify a devicetree from a devkit to remove things you don't have on your custom hardware.

Improvements in the form of examples or wiki additions/updates would be greatly appreciated, so if you could keep notes as you go about things which would have helped to be documented here or elsewhere I'm sure others will find them helpful as well.

Thank you so much Dan! That's one guide I hadn't found but I'll give that a look and see if it leaves me with fewer dead ends. It seems that the guides make assumptions about the carriers and if you're doing something truly embedded as we are, that might not be appropriate.
