BBB - Yocto - Kirkstone - USB connection

General Discussion

Hello, I have question,

I have followed this guide How the Yocto Project Brings Linux to the BBB – Takeoff Technical
And build new image based on “kirkstone”.
core-image-full-cmdline

I use Ubuntu 18 KDE Plasma.
But $lsusb doesn’t return new devices
$ ifconfig -a doesnt show new network interfaces
However I use FTDI serial to USB convertor and the hardware serial is working.
So the image that I have build is working but I don’t have usb connection.

Is the image that I use correct,I don’t see nothing in $ lsusb?
How can I make it work?

I followed this guide too Building BeagleBone Systems with Yocto, it is using poky-dunfell distribution.
But it is the same thing, when I’m building the yocto myself I don’t have the internet connection through USB.

Any ideas, do I need to set some parameter in local.conf or something?

Btw when building kirkstone, I’m not downloading
meta-openembeded and meta-beagleboard which are downloaded and added like layers here

Do I need some of these to make the USB/Ethernet connection works?

Or do I need to add thigns to the local.conf? For example:
IMAGE_INSTALL_APPEND = " openssh "

Solution!

The USB gadget hasn’t been enabled. I had to enable it.
To do this I created append recipe for the kernel - linux-yocto_5.15.bbappend which calls cfg file.
MY_CONFIG_FILE = “${TOPDIR}/…/poky/meta-mms-bsp/recipes-kernel/linux”
SRC_URI += “file://${MY_CONFIG_FILE}/my_custom.cfg”

my_custom.cfg file contains
CONFIG_USB_ETH=y
CONFIG_USB_G_NCM=m
CONFIG_USB_MASS_STORAGE=y

Also I added tothe image recipe CORE_IMAGE_EXTRA_INSTALL += “usbinit”

Hello Nichirenshu,

What is meta-mms-bsp? Where is it from or it is created by yourself?

Thanks!

Hello,

@RobertCNelson , do you know of anyone updating this meta-beagleboard thing for poky in recent times?

It seems worth it to have some working for the BBB or is it for reference only?

I don’t believe meta-beagleboard has been updated in over 10 years…

Okay. No issue…probably just wishful thinking on my part.

I guess someone or something should update it! Maybe not me but someone w/ more experience might want to jab at it?

This is layer created by me. The important thing is to make in your own layer a kernel append recipe. In this case linux-yocto_5.15.bbappend.
Put the rows from my previous post inside and make own custom.cfg file that contains these USB settings.
(Actually you can make the append file with universal name, not depending of the selected kernel version but I forgot how exactly was the naming in this case)

The universal name for this append recipe is linux-yocto_%.bbappend, I just checked this.
