Yocto BSP Mickledore-LF6.1.22 : How to add Network Manager

[khang_letruong]

Dear Community,

I was able to add the Network Manager into the Yocto Hardknott by adding following lines into the <build-folder>/ conf/local.conf :

IMAGE_INSTALL_remove += " ofono connman connman-gnome connman-conf"
IMAGE_INSTALL_remove += " packagegroup-core-tools-testapps"
PACKAGE_EXCLUDE += "ofono connman connman-gnome connman-conf"
PACKAGE_EXCLUDE += "connman-client connman-tools"
PACKAGE_EXCLUDE += "packagegroup-core-tools-testapps"
DISTRO_FEATURES_remove = " 3g"
IMAGE_INSTALL_append = " networkmanager networkmanager-nmcli modemmanager"
IMAGE_INSTALL_append = " networkmanager-bash-completion"
PACKAGECONFIG_append_pn-networkmanager = " modemmanager ppp"

On the newer Yocto BSP Mickledore-LF6.1.22, I did nearly the same :

IMAGE_INSTALL:remove = " ofono connman connman-gnome connman-conf"
IMAGE_INSTALL:remove = " packagegroup-core-tools-testapps"
PACKAGE_EXCLUDE += "ofono connman connman-gnome connman-conf"
PACKAGE_EXCLUDE += "connman-client connman-tools"
PACKAGE_EXCLUDE += "packagegroup-core-tools-testapps"
DISTRO_FEATURES:remove = " 3g"
IMAGE_INSTALL:append = " networkmanager networkmanager-nmcli modemmanager"
#IMAGE_INSTALL:append = " networkmanager-bash-completion"
PACKAGECONFIG:append_pn-networkmanager = " modemmanager ppp"

with an exception that networkmanager-bash-completion is NOT appended as it generated error during the bitbaking.  The nmcli is installed but not working (i.e. it does not show the available network interface with nmcli con show command) however. Current behavior :

root@viperimx8mp:~# nmcli con show
NAME UUID TYPE DEVICE
lo 132bd08f-c6db-41f4-86b8-60bf6345ad56 loopback lo

Expected behavior (in older BSP Hardknott LF-5.10.72) :

root@viperimx8mp:~# nmcli con show
NAME                UUID                                  TYPE      DEVICE
Wired connection 1  fca1ee92-220b-393a-af88-32613a404fe6  ethernet  eth0

Could you advise, please ?

Hi @khang_letruong!

Thank you for contacting NXP Support!

If you plan to use systemd-networkd as the primary network configuration utility, you should remove connman first (when using a console-only image, you won't need to remove connman-gnome). You can use the package manager to remove the package from pre-built images by invoking.

in local.conf

# Remove connman
IMAGE_INSTALL:remove = " connman"
IMAGE_INSTALL:remove = " connman-client"
IMAGE_INSTALL:remove = " connman-gnome"
IMAGE_INSTALL:remove = " connman-plugin-wifi"
IMAGE_INSTALL:remove = " connman-plugin-ethernet"
IMAGE_INSTALL:remove = " connman-plugin-loopback"
# Add NetworkManager
IMAGE_INSTALL:append = " networkmanager"
IMAGE_INSTALL:append = " modemmanager"

Best Regards!

Hi @Chavira ,

Unfortunately with your suggestion, I also have same issue as described here : https://community.nxp.com/t5/i-MX-Processors/MICKELDORE-6-1-36-how-to-add-bitbake-recipe-for-Network...

Hi @khang_letruong!

Sorry for the late response.

I can add the packages to my evk board.

The steps that I following are the next:

1: Compile the image only removing conman:

On local.conf:

# Remove connman
IMAGE_INSTALL:remove = " connman"
IMAGE_INSTALL:remove = " connman-client"
IMAGE_INSTALL:remove = " connman-gnome"
IMAGE_INSTALL:remove = " connman-plugin-wifi"
IMAGE_INSTALL:remove = " connman-plugin-ethernet"
IMAGE_INSTALL:remove = " connman-plugin-loopback"

# Add NetworkManager
#IMAGE_INSTALL:append = " networkmanager"
#IMAGE_INSTALL:append = " modemmanager"

2: After the image is generated you have to clean the image:

Bitbake -c clean <Image>

3: Add the packages to local.conf:

On local.conf:

# Remove connman
IMAGE_INSTALL:remove = " connman"
IMAGE_INSTALL:remove = " connman-client"
IMAGE_INSTALL:remove = " connman-gnome"
IMAGE_INSTALL:remove = " connman-plugin-wifi"
IMAGE_INSTALL:remove = " connman-plugin-ethernet"
IMAGE_INSTALL:remove = " connman-plugin-loopback"

# Add NetworkManager
IMAGE_INSTALL:append = " networkmanager"
IMAGE_INSTALL:append = " modemmanager"

4: compile the image to generate the final image with the added packages:

Bitbake <Image>

Best Regards!

Hi @Chavira,

I tried your suggestion but there's still following error :

Hi!

I got the same error the first time because I compiled the image without removing Connman first.

Please, try to delete your Yocto Project and follow the steps I provide before.

Best Regards!

Hi @Chavira ,

Should I remove Connection Manager from and add Network Manager into the conf/local.conf at the same time or should I bitbake with Connection Manager removed first then re-bitbake with Network Manager added later?

Khang

Hello @khang_letruong ,

I got the same error.

I found the below package also contain the connman. So, remove the connman's package in the .bb file.

poky/meta/recipes-core/packagegroups/packagegroup-core-tools-testapps.bb

Then build the image again. The build will be succeed.

Hi @khang_letruong!

Yes, you have to compile the image deleting Connection Manager and then, do a clean, and finally add the packages to add Network Manager.

1: Compile the image only removing conman:

On local.conf:

# Remove connman
IMAGE_INSTALL:remove = " connman"
IMAGE_INSTALL:remove = " connman-client"
IMAGE_INSTALL:remove = " connman-gnome"
IMAGE_INSTALL:remove = " connman-plugin-wifi"
IMAGE_INSTALL:remove = " connman-plugin-ethernet"
IMAGE_INSTALL:remove = " connman-plugin-loopback"
# Add NetworkManager
#IMAGE_INSTALL:append = " networkmanager"
#IMAGE_INSTALL:append = " modemmanager"

2: After the image is generated you have to clean the image:

Bitbake -c clean <Image>

3: Add the packages to local.conf:

On local.conf:

# Remove connman
IMAGE_INSTALL:remove = " connman"
IMAGE_INSTALL:remove = " connman-client"
IMAGE_INSTALL:remove = " connman-gnome"
IMAGE_INSTALL:remove = " connman-plugin-wifi"
IMAGE_INSTALL:remove = " connman-plugin-ethernet"
IMAGE_INSTALL:remove = " connman-plugin-loopback"
# Add NetworkManager
IMAGE_INSTALL:append = " networkmanager"
IMAGE_INSTALL:append = " modemmanager"

4: compile the image to generate the final image with the added packages:

Bitbake <Image>

Hi Alejandro,

Thanks for confirming the steps with the fresh yocto environment (after removing the build folder). That was however what I did so far in the following video but the error still persists : https://drive.google.com/file/d/1RTXGPiNOFMYx6835cYJzHVzsizojIMtj/view?usp=share_link
