102 SDIO WIFI Verification

1. Hardware

The hardware connection is as follows.

  • EVB

    1. Only the nor flash has been verified, connect as shown in the figure below.

    2. SDIO WIFI connection is as follow.

  • Demo Board

    Verify NOR and NAND FLASH.

2. Software

The content to be modified is as follows:

  • EVB

    1. Modify path kernel\arch\arm\boot\\dts\pioneer3.dtsi.

    2. Modify the following content.

  • Demo Board

    1. Modify path kernel\arch\arm\boot\dts\pioneer3-demo.dtsi

    2. Modify the following content.

3. Config

  • EVB

    make dispcam_p3_spinand.glibc-9.1.0-s01a.64.qfn128_defconfig

  • demo board

    make
dispcam_p3_spinand.glibc-9.1.0-s01a.64.qfn128.demo_defconfig

make clean;make image-nocheck -j8

When compiling Ikayaki and Takoyaki:

  1. Support multi-threaded compilation.

  2. Compile the kernel simultaneously by default.

4. Burn Software

Refer to environment setup.

5. Verification

  1. Check whether the sdio device is recognized normally.

    Check the boot log, if there is the following print, it has been recognized normally.

  2. Check whether the wifi related files are in the board.

    Path: /config/wifi.

  3. Modify the default connection file.

    Modify vi /appconfigs/wpa_supplicant.conf：

    network={

ssid="nova3"

psk="12345678"

}

  4. Run the following commands.

    1. Execute ./102_demo.sh in /config/wifi

    2. Connect to the wifi corresponding to wpa_supplicant.conf normally.

    3. Use the command to test whether it is connected: ping -I wlan0 14.215.177.39.

6. Verify AP Mode

Modifty the code based on the STA mode.

  1. Path: project\image\configs\rootfs.mk.

  2. Compile ap into the program.

    The nor flash memory is small, and the program is not compiled into the program by default during development until it needs to be verified. After the functions are added, the program will be compiled into the program by default according to the usage of the nor flash partition.

  3. Use the above configuration, recompile and burn the program.

7. Enable AP Mode

  1. Execute the following commands.

    export PATH=/config/wifi:$PATH
export LD_LIBRARY_PATH=/config/wifi:$LD_LIBRARY_PATH

touch /appconfigs/hosts
mkdir -p /tmp/wifi/run
chmod 777 /tmp/wifi/run
mkdir -p /appconfigs/misc/wifi/
mkdir -p /var/wifi/misc/
mkdir -p /var/lib/misc/
mkdir -p /var/run/hostapd/
rm -f /dev/random
ln -s /dev/urandom /dev/random
insmod ./ssw102b_wifi_sdio.ko
mdev -s

ifconfig p2p0 up
ifconfig p2p0 192.168.1.100 netmask 255.255.255.0

cd /config/wifi
./hostapd -B /config/wifi/hostapd.conf
./dnsmasq -i p2p0 --no-daemon -C /config/wifi/dnsmasq.conf &

  2. Connect with another device.

    ssid: ssw101bap

    passwd: 12345678

    You can modify the ssid and password of hostapd.conf.
