WIFI

The original factory did not provide the WiFi driver source code, only provided the.ko file.As can be seen from rootfs.mk, the copy of wifi-related files is controlled from interface_wlan.

# vi project/image/configs/i2m/rootfs.mk

# ls project/release/nvr/i2m/common/glibc/8.2.1/wifi/*

According to the project/configs/nvr/i2m/8.2.1/spinand.glibc.011a.64 –> nvr_i2m_display_glibc_tailor.mk，You can find the interface_wlan defined in the project/release/customer_tailor/nvr_i2m_display_glibc_tailor.mk

# vi project/configs/nvr/i2m/8.2.1/spinand.glibc.011a.64

# find ./project/ -name nvr_i2m_display_glibc_tailor.mk

# vi project/release/customer_tailor/nvr_i2m_display_glibc_tailor.mk

You can seen defind vlaue is enable.

• DTS configuration

As can be seen from the schematic diagram, wifi is USB interface (USB1),It is configured by default and does not need to be modified.

# vi infinity2m-doublenet.dtsi 

# vi infinity2m-ssc011a-s01a-padmux-rgb565-rmii.dtsi

After the system starts, the device you can see through lsusb is WiFi module.(1b20:8888)

• Load driver
  /config/wifi/ssw01bInit.sh Auto load drive:

  # /config/wifi/ssw01bInit.sh

  

After the driver is loaded, we can see the WLAN 0 network card:
