[yocto] Error trying to generate Raspberry Pi initramfs

[Greg Wilson-Lindberg]

I'm trying to generate an initramfs for a raspberry pi 3 for a sumo build. We are based off of the Qt boot2qt system.

I have followed the instructions in the meta-raspberrypi.pdf documentation, section 3.14 Image with Initramfs.

I edited the meta-raspberrypi/recipes-kernel/linux/linux-raspberry.inc file and added the variables into my local.conf file. I created a rpi-minimal-initramfs.bb recipe and it is created when I build the system. But the command line that is put into the boot partition is:

dwc_otg.lpm_enable=0  root=/dev/mmcblk0p2 rootfstype=ext4 rootwait    fbcon=map:10 fbcon=font:VGA8x8

No initramfs.

In the linux-raspberry.inc file, after the insertion point for the new kernel variables, there is a test for KERNEL_INITRAMFS. I tried setting this in my local.conf file, but when I do I get an error for a missing file:

| /home/..../tmp/deploy/images/raspberrypi3/uImage1-raspberrypi3.bin: No such file or directory

So, apparently that can't be set directly.

There seems to be something missing in the instructions in the meta-raspberrypi.pdf documentation. Anyone that has any experience with setting this up and can help me figure out what I'm missing, I would greatly appreciate the help.
