[yocto] Wifi Module + udev configs

[Raul Rosetto Munoz]

Hello All,
I need to configure my yocto project to work with wifi dongle realteck
rtl8192cu.

I'm using this building configuration:

Build Configuration:
BB_VERSION        = "1.16.0"
TARGET_ARCH       = "arm"
TARGET_OS         = "linux-gnueabi"
MACHINE           = "beaglebone"
DISTRO            = "poky"
DISTRO_VERSION    = "1.3"
TUNE_FEATURES     = "armv7a vfp neon cortexa8"
TARGET_FPU        = "vfp-neon"
meta
meta-yocto        = "danny:47b0864fbd65746558d8186450c182d98bac78ca"
meta-ti           = "danny:1e898d9b619545dadf2ececad81cd58cdf37c8cd"
meta-oe


First, I built all the modules needed for the wifi dongle and installed in
Angstron standard distro.

This worked well and I had the following lsmod:

Module                  Size  Used by
arc4                    1183  2
rtl8192cu              73042  0
rtl8192c_common        52118  1 rtl8192cu
rtlwifi                57197  1 rtl8192cu
mac80211              149274  3 rtl8192cu,rtl8192c_common,rtlwifi
cfg80211              122225  2 rtlwifi,mac80211
rfkill                 14659  1 cfg80211
g_mass_storage         24014  0
ipv6                  209407  14

Then I tried to do the same for my project and installed the following
packages:
packages:

IMAGE_INSTALL_append = " \
        libxml2 \
        gnupg \
        curl \
        gdb \
        curl-dev \
        minicom \
        lrzsz \
        libcap \
        ppp \
        ppp-dialin \
        usbutils \
        mtd-utils \
        openssh \
        dhcp-server \
        dhcp-client \
        kernel-modules \
        udev-extraconf \
        wpa-supplicant \
        i2c-tools \
        update-modules \
        modutils-initscripts \
        zeroconf \
        wireless-tools \
        openssl \
        net-tools \
        busybox \
        linux-firmware \
        systemd \
        connman"

My first problem is that the module does not go up automatically rtl8192cu
different than Angstron distro that when I plug the dongle all modules rise.

Another important difference is that on Angstron distro I have on /lib/udev
the "firmware" binary file.  I really was not able to install this
functionality in udev.

Please some one can Help me to configure this device?

And How to make this firmware binary go to /lib/udev?

I have not found the way to configure the udev features.

Thanks all for help.
