Replace nvpmodel.conf with a custom one in dunfell-l4t-r32.6.1

Hi

I want to replace the default nvpmodel.conf file. That has been working fine using the trick described in #89 where you append the recipes for tegra-binaries and tegra-nvpmodel-base. That was on dunfell32.4.3.

However, now I've switched to dunfell32.6.1 and this trick it not working anymore. The error I'm getting is

| install: cannot stat '/home/myhomedir/repos/meta-mymetalayer/build/tmp/work/jetson_tx2_devkit-poky-linux/tegra-nvpmodel-base/32.6.1-20210726122859-r0/tegra-nvpmodel-base-32.6.1-20210726122859/config-replacements/nvpmodel.conf': No such file or directory

Apparently, the file nvpmodel.conf cannot be found. I am also surprised how this trick even worked in the first place as I thought that recipes don't interact with each other.
I am building for a Jetson TX2.

Is there another recommended way to get a custom nvpmode.conf into the build?
Can this trick be fixed?

Starting with R32.6.1, we switched to populating most of the BSP files using NVIDIA's deb packages, rather than extracting them from the L4T tarball. That should simplify things, as you can use a bbappend directly on the tegra-nvpmodel recipe to add your custom file to the SRC_URI, like you would do with most other recipes.

Thank you! That helped me.
I ended up appending to the tegra-nvpmodel-base since this is the one that deals with the nvpmodel conf file. Using the tegra-nvpmodel directly caused a error when building the image. Something along the lines: "There are two recipes trying to install the same file".
I also opted to append to the nvpmodel config instead of replacing it completely.

In tegra-nvpmodel-base_%.bbappend
do

FILESEXTRAPATHS_prepend := "${THISDIR}/files:"

SRC_URI += "file://nvpmodel.txt"

NVPMODEL_CONFIG_DEFAULT= "5"
do_install:append:tegra186() {
        cat ${WORKDIR}/nvpmodel.txt >> ${D}${sysconfdir}/nvpmodel.conf
}

Oops, right, that's the one. I had to split some of the recipes so we could add stuff from the layer on top of what's in the L4T packages.
