Other Parts Discussed in Thread: WL1837, MIO, WL1271
Tool/software: Linux
Hello.
I'm trying to integrate WL1837MODCOM8I module on AVNET UltraZed board.
My kernel version is 4.9.0-xilinx-v2017.2
I use petalinux 2017.2 tools to build and obtain image.ub and BOOT.BIN to load on the board.
In order to integrate WL1837MODCOM8I on the board i've done the following steps:
I've enabled all these features on the kernel
# Need for PLT calibration modes
CONFIG_NL80211_TESTMODE=y
# MAC 80211
CONFIG_WLAN=y
CONFIG_WIRELESS=y
CONFIG_WIRELESS_EXT=y
CONFIG_WL12XX_PLATFORM_DATA=y
CONFIG_KEYS=y
CONFIG_SECURITY=y
CONFIG_CRYPTO=y
CONFIG_CRYPTO_ARC4=y
CONFIG_CRYPTO_ECB=y
CONFIG_CRYPTO_AES=y
CONFIG_CRYPTO_MICHAEL_MIC=y
CONFIG_CRYPTO_RNG=y
CONFIG_CRYPTO_AEAD=y
CONFIG_CRYPTO_CCM=y
CONFIG_CRYPTO_GCM=y
I've modified the system-user.dtsi file, in order to add on global system-top.dts (main device-tree), the wifi entry. System-user.dtsi is
/include/ "system-conf.dtsi"

When the board starts doing ifconfig-a i'm not able to see wlan0 interface and obviously doing ifconfig wlan0 up kernel says "No such device"
On proc file /sys/firmware/devicetree/base/wlcore i see the following folder
board-ref-clock compatible interrupt-parent irq name platform-quirks
cat of compatible gives me ti,wl1837
So it seems that kernel recognize correctly wifi tree
What's wrong?, What's missing? Whi i'm not able to see interface wlan0
Do i need to integrate wlconf on my project or this was just for old kernel
Hope i receive your suggestions soon
Thanks in advance
Regards
Alessandro
