How to use "modprobe" command in app?

[tanaporn_y]

I want to modprobe mac80211 by using app but it was error.

    system("/home/root/wf200.sh &");
	sleep(2);
    system("ifconfig wlan0 up");

How to use command in the app c file?

[jyijyi]

how abut you change your wf200.sh to use absolute path like /sbin/modprobe?

[tanaporn_y]

I had wrote it right this.

#!/bin/sh
modprobe mac80211
insmod wfx.ko
echo 13 > /sys/class/gpio/export

[jyijyi]

how about changing it to " /sbin/modprobe mac80211" and re-run the legato app?

[tanaporn_y]

got this:

I have added this line and got this

PATH=/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin;

ok, it is better, at least there is no modprobe problem
