Set the environmental variable bootcmd to specify the boot type. The following script shows the values of the boot

variables for USB (usbboot) and TFTP (tftpboot) server required to boot the kernel.

bootcmd=run usbboot

bootargs=root=/dev/ram rw console=ttyS0,115200

usbboot=usb start;setenv bootargs;fatload usb 0:1 1000000 uImage-t1023rdb.bin;fatload

3. Set up the access point in kernel

Perform the following steps to set up access point in kernel using the scripts given below:

a. Load the module to optimize the CPU utilization

Use the following command to load the module for the optimum utilization of CPU:

modprobe br_ol

echo 1 > /proc/sys/net/core/ol_forward_enable

b. Bring up the Wi-Fi cards

Use the following script to bring up the 802.11ac Wave 2 Wi-Fi cards.

export PATH=$PATH:/etc/ath

cfg -x

cfg -a AP_STARTMODE=dual

cfg -a AP_MODE=ap-wds

cfg -a AP_RADIO_ID=0

cfg -a AP_PRIMARY_CH=36

cfg -a AP_CHMODE=11ACVHT80

cfg -a AP_SSID=QCA_11AC_5G_1

cfg -a RX_CHAINMASK=15

cfg -a TX_CHAINMASK=15

iwconfig ath0 txpower 21

iwpriv ath0 wds 1

cfg -a AP_MODE_2=ap-wds

cfg -a AP_RADIO_ID_2=1

cfg -a AP_PRIMARY_CH_2=149

cfg -a AP_CHMODE_2=11ACVHT80

cfg -a AP_SSID_2=QCA_11AC_5G_2

cfg -a RX_CHAINMASK_2=15

cfg -a TX_CHAINMASK_2=15

iwconfig ath1 txpower 21

iwpriv ath1 wds 1

cfg -a CMWMODE=2

cfg -c

apup

NOTE

Use the following commands to modifyWi-Fi module MAC address in Linux

kernel:

iwpriv wifi0 setHwaddr `fw_printenv -n wifi0addr`

iwpriv wifi1 setHwaddr `fw_printenv -n wifi1addr`

c. Set the bridge connection

Use the following script to set up the bridge connection.

brctl addbr br0

brctl addif br0 ath0

brctl addif br0 fm1-mac4

ifconfig fm1-mac4 up
