wifi binding on imx6sl evk based board
来源：互联网 发布：网络d是什么意思 编辑：程序博客网 时间：2024/05/22 06:14
We are having problem with board that is based on imx6sl evk and rtl8192cu (chip on wifi module is RTL8188CTV). The wifi module is on USB interface.
We integrated rtl8192cu driver from another package, we used manual supplied by realtek to integrate there driver into android (from zip fileRTL8188C_8192C_USB_linux_v4.0.2_9000.20130911.zip pdf file \android_ref_codes_JB_4.2\Realtek_Wi-Fi_SDK_for_Android_JB_4_2.pdf).
The driver is build as part of the kernel, not module. We used there's wpa_supplicant, that came with realteks package (wpa_supplicant_8_jb_4.2_rtw_r8680.20130821.tar.gz).
Package is from this site: http://www.realtek.com/downloads/downloadsView.aspx?Langid=2&PFid=48&Level=5&Conn=4&ProdID=277&DownTypeID=3&GetDown=false&Downloads=true
RTL8192CU for Linux/Android
Firmware is from this link: rtl819x - Linux Wireless
Using serial interface terminal, we tested the wlan0 interface, we can bring it up, and get ip number:

We need to use dhcpcd wlan0 command, the suggested init.rs service doesn't work, but thats not the problem.
Our problem is that binding from android ui and kernel isnt working.
When we tried to turn on wifi, from Settings>Wifi in Android UI, the slider button can move and change to On state, but the message on display "To see available networks, turn WiFi on" is still there.
in logcat we get:
D/WifiService( 2363): setWifiEnabled: true pid=2363, uid=1000
After that we can't move slider back.
When we exit that menu and return, the slider is back in Off state.
Using wifi from shell, we can get all the other wifi networks:

We also added permissions for wifi in android ..
Please, ask me if you need more details, I kept track of all the changed done in the android and kernel.
Logcat with DBG for classes in wifi is also available.
Does anyone have any idea about this problem? Could you help us, please? We wasted a lot of time on this.
Yes, we manage to get wifi working. Here are info's in more detail, so if anybody else has problem ...
We build driver as part of the kernel:

WIFI_DRIVER_FW_PATH_STA := ""
WIFI_DRIVER_FW_PATH_AP := ""
WIFI_DRIVER_FW_PATH_P2P := ""

We disabled p2p, since we dont need it:
vim device/fsl/imx6/{yourboard}.mk
PRODUCT_COPY_FILES += \
#frameworks/native/data/etc/android.hardware.wifi.direct.xml:system/etc/permissions/android.hardware.wifi.direct.xml
or
rm out/target/product/{yourboard}/system/etc/permissions/android.hardware.wifi.direct.xml
or just remount system partition:
root@{yourboard}:/ # mount -o remount, rw /system;
and remove xml:
root@{yourboard}:/ # rm /system/etc/permissions/android.hardware.wifi.direct.xml
edit:
root@{yourboard}:/ # busybox vi system/etc/permissions/required_hardware.xml
or
vim device/fsl/{yourboard}/required_hardware.xml
or
vim out/target/product/{yourboard}/system/etc/permissions/required_hardware.xml
<!--
<feature name="android.hardware.wifi.direct" />
-->
If you use it as module, you will need to add it also in PRODUCT_COPY_FILES
You need to correct init scripts, leave just this lines:
(this is from: http://blog.linuxconsulting.ro/2010/04/porting-wifi-drivers-to-android.html )
You can do it directly to out folder:
vim out/target/product/{yourboard}/root/init.rc
or/and (rebuild the whole system):
vim device/fsl/imx6/imx6.mk
mkdir /system/etc/wifi 0770 wifi wifi
chmod 0770 /system/etc/wifi
chmod 0660 /system/etc/wifi/wpa_supplicant.conf
chown wifi wifi /system/etc/wifi/wpa_supplicant.conf
#wpa_supplicant control socket for android wifi.c (android private socket)
mkdir /data/misc/wifi 0770 wifi wifi
mkdir /data/misc/wifi/sockets 0770 wifi wifi
chmod 0770 /data/misc/wifi
chmod 0660 /data/misc/wifi/wpa_supplicant.conf
chown wifi wifi /data/misc/wifi
chown wifi wifi /data/misc/wifi/wpa_supplicant.conf
setprop wifi.interface wlan0
setprop wlan.driver.status "ok"
#setprop wifi.ap.interface wlan0
#and also remove this lines:
# mkdir /data/system/wpa_supplicant 0771 wifi wifi
# chmod 0771 /data/system/wpa_supplicant
# symlink /data/misc/wifi/wpa_supplicant /data/system/wpa_supplicant
you can read it in that blog link, about unix/android standard socket setup.
vim out/target/product/{yourboard}/root/init.freescale.rc
or/and
vim device/fsl/{yourboard}/init.rc
#this is the only supplicant service and dhcpcd service for wifi that we use:
service rtw_suppl /system/bin/wpa_supplicant -dd -iwlan0 -Dnl80211 \
-c/data/misc/wifi/wpa_supplicant.conf
socket wpa_wlan0 dgram 660 wifi wifi
class main
disabled
oneshot
service dhcpcd_wlan0 /system/bin/dhcpcd -aABKL
class main
disabled
oneshot
service iprenew_wlan0 /system/bin/dhcpcd -n
class main
disabled
oneshot
To keep it clean (it doesnt effect wifi):
vim device/fsl/imx6/imx6.mk
PRODUCT_PACKAGES += \
rtw_suppl \
We needed to make a little change in wifi_realtek.c since our jb is 4.3:
vim hardware/realtek/wlan/libhardware_legacy/wifi/wifi_realtek.c
int wifi_start_supplicant(int p2p_supported)
..
wifi_stop_supplicant(p2p_supported);
….
int wifi_stop_supplicant(int p2p_supported){
char supp_status[PROPERTY_VALUE_MAX] = {'\0'};
int count = 50; /* wait at most 5 seconds for completion */
if (p2p_supported) {
property_get("wifi.supplicant", supplicant_name, P2P_SUPPLICANT_NAME);
snprintf(supplicant_prop_name, PROPERTY_KEY_MAX, P2P_PROP_NAME, supplicant_name);
} else {
property_get("wifi.supplicant", supplicant_name, SUPPLICANT_NAME);
snprintf(supplicant_prop_name, PROPERTY_KEY_MAX, SUPP_PROP_NAME, supplicant_name);
}
Our problem was wrong supplicant name in prop setup. And, when wifi starts it first stops supplicant, and it wasn’t able to transfer that info through system. It was quite fun tracking this problem.
vim ./frameworks/base/wifi/java/android/net/wifi/WifiStateMachine.java
mWifiNative.killSupplicant(mP2pSupported);
if(mWifiNative.startSupplicant(mP2pSupported)) {
setWifiState(WIFI_STATE_ENABLING);
if (DBG) log("Supplicant start successful");
mWifiMonitor.startMonitoring();
transitionTo(mSupplicantStartingState);
} else {
loge("Failed to start supplicant!!");
}

igorpadykov 2014-4-25 上午2:36 （回复 Zoran Lukic）
Hi, Zoran
what Android was used, is it Freescale Android (link below) ?
IMX6_JB43_110_ANDROID_SOURCE_BSP
: i.MX 6Quad, i.MX 6Dual, i.MX 6DualLite,i.MX 6Solo and i.MX 6Sololite Android jb4.3_1.1.0 0 BSP, Documentation and Source Code
i.MX 6SoloLite Evaluation Kit
Also very often WiFi modules have different firmware, so different drivers are needed, though module
name may the same. Have you contacted Realtek for updated version of driver for this specific module ?

Hello,
Thank you for answering,
Yeah, I wanted to add that info. It was JB4.3 and the Realtek porting for rtl8192cu driver is for JB4.2.
Some more porting work was needed to be done that wasnt in the manual.
Also we are currently working on nfs, there shouldnt be some permissions problem.
We put every all firmware files in the root fs (nfs) just in case.

but driver source it askes for:

also, driver is build in the kernel, from boot:

because system handles driver. But I will check out this, more.
Other thing is that wpa_supplicant isnt not called from init script, there is no trace of it in logcat.

If we manual start dhcp for wlan0, we can get wifi ip address (in my previous post).
When we manually call wpa_supplicant:
wpa_supplicant -iwlan0 -c/system/etc/wifi/wpa_supplicant.conf -B
we get this in logcat:
--------- beginning of /dev/log/main
I/wpa_supplicant( 2938): Successfully initialized wpa_supplicant
E/wpa_supplicant( 2938): nl80211: Could not add multicast membership for scan events: -2 (No such file or directory)
E/wpa_supplicant( 2938): Failed to initialize driver 'nl80211'
In board config file:
(./device/fsl/evk_6sl/BoardConfig.mk file)
BOARD_WPA_SUPPLICANT_DRIVER := NL80211
BOARD_HOSTAPD_DRIVER := NL80211
in both
./external/wpa_supplicant_8/wpa_supplicant/android.config
and
./external/wpa_supplicant_8/hostapd/android.config
CONFIG_DRIVER_NL80211=y
We didn't contacted Realtek yet, we believe that we have some binding problems with driver and android ui.
Also, slider button for wifi in the Settings menu in the Android ui seamed not to be connected to Settings>Wifi button.
I can move button in Settings menu, to On state. And the enter the Settings>Wi-Fi and the button is in Off state.
Exiting Settings>Wi-Fi menu and entering it again, it shows that button is back in Off state.
Toggling wifi button to Off state isn't possible, after it was set to On state by us.
After moving the wifi button slider to Off state we get this in logcat:
D/WifiService( 2401): setWifiEnabled: true pid=2561, uid=1000
E/WifiService( 2401): Invoking mWifiStateMachine.setWifiEnabled
in system/core/include/private/android_filesystem_config.h file we can see uid's
#define AID_SYSTEM 1000 /* system server */
#define AID_WIFI 1010 /* wifi subsystem */
Do we need to register platform driver callbacks, but this is usb module, it shouldn't need that?
Is it some nfs permission related issue with wifi?
So, what do you think?

Re: wifi binding on imx6sl evk based board
igorpadykov 2014-5-6 上午12:34 （回复 Zoran Lukic）Hi Zoran, I got advice from our expert:
I had been reading about this issue and also i read the description from the client and seem
there's some missing configuration which the client could try.
First of all try to set BOARD_WPA_SUPPLICANT_DRIVER to WEXT in the Android BSP.
Also you need to provide a proper wpa configuration file for your device.
For more details check this reference:
PaNiC Random Rant (or how we used to call it: .plan): Porting WiFi drivers to Android
Hope this helps

Re: wifi binding on imx6sl evk based board
Zoran Lukic 2014-5-6 下午2:24 （回复 igorpadykov）Yep, I tried this link.
In manual provided with rtl wifi driver, it states to use new nl80211 interface.
BoardConfig.mk
BOARD_WPA_SUPPLICANT_DRIVER=NL80211
Problem is that Wifi slider switch cant be moved, but nothing happens, so some binding or some permissions are problem. This is done in nfs.
When slider is moved to On position in logcat we get this:
D/WifiService( 2401): setWifiEnabled: true pid=2561, uid=1000
E/WifiService( 2401): Invoking mWifiStateMachine.setWifiEnabled
there should be more data or some error or permission staff for wifi, after this.
wpa_supplicant doesnt start automatically, but it is in init.freescale.rc script. It can start manually with nl80211 driver.
WEXT, I will try this again, thank you. I am not sure it will work, i dont think the driver is problem. I can scan and get all networks in area, using shell.

Robert McLean 2014-5-27 下午1:46 （回复 Zoran Lukic）
We have a similar setup and are having the same problems. Right down to the same bogus IP address reported by netconfig after dhcpcd seems to believe it got an address from the DHCP server on my Access Point.
Has there been any activity on this?

正确答案Re: wifi binding on imx6sl evk based board
Zoran Lukic 2014-5-28 上午6:52 （回复 Robert McLean）Yes, we manage to get wifi working. Here are info's in more detail, so if anybody else has problem ...
We build driver as part of the kernel:

WIFI_DRIVER_FW_PATH_STA := ""
WIFI_DRIVER_FW_PATH_AP := ""
WIFI_DRIVER_FW_PATH_P2P := ""
WIFI_DRIVER_FW_PATH_PARAM := ""
We disabled p2p, since we dont need it:
vim device/fsl/imx6/{yourboard}.mk
PRODUCT_COPY_FILES += \
#frameworks/native/data/etc/android.hardware.wifi.direct.xml:system/etc/permissions/android.hardware.wifi.direct.xml
or

and remove xml:

vim device/fsl/{yourboard}/required_hardware.xml
or
vim out/target/product/{yourboard}/system/etc/permissions/required_hardware.xml
<!--
<feature name="android.hardware.wifi.direct" />
-->
If you use it as module, you will need to add it also in PRODUCT_COPY_FILES
You need to correct init scripts, leave just this lines:
(this is from: http://blog.linuxconsulting.ro/2010/04/porting-wifi-drivers-to-android.html )
You can do it directly to out folder:
vim out/target/product/{yourboard}/root/init.rc
or/and (rebuild the whole system):
vim device/fsl/imx6/imx6.mk
mkdir /system/etc/wifi 0770 wifi wifi
chmod 0770 /system/etc/wifi
chmod 0660 /system/etc/wifi/wpa_supplicant.conf

chown wifi wifi /data/misc/wifi
chown wifi wifi /data/misc/wifi/wpa_supplicant.conf
setprop wifi.interface wlan0
setprop wlan.driver.status "ok"
#setprop wifi.ap.interface wlan0
#and also remove this lines:
# mkdir /data/system/wpa_supplicant 0771 wifi wifi
# chmod 0771 /data/system/wpa_supplicant
# symlink /data/misc/wifi/wpa_supplicant /data/system/wpa_supplicant
you can read it in that blog link, about unix/android standard socket setup.

To keep it clean (it doesnt effect wifi):
vim device/fsl/imx6/imx6.mk
PRODUCT_PACKAGES += \
rtw_suppl \
We needed to make a little change in wifi_realtek.c since our jb is 4.3:
vim hardware/realtek/wlan/libhardware_legacy/wifi/wifi_realtek.c
int wifi_start_supplicant(int p2p_supported)
..
wifi_stop_supplicant(p2p_supported);
….
int wifi_stop_supplicant(int p2p_supported){
char supp_status[PROPERTY_VALUE_MAX] = {'\0'};
int count = 50; /* wait at most 5 seconds for completion */
if (p2p_supported) {
property_get("wifi.supplicant", supplicant_name, P2P_SUPPLICANT_NAME);
snprintf(supplicant_prop_name, PROPERTY_KEY_MAX, P2P_PROP_NAME, supplicant_name);
} else {
property_get("wifi.supplicant", supplicant_name, SUPPLICANT_NAME);
snprintf(supplicant_prop_name, PROPERTY_KEY_MAX, SUPP_PROP_NAME, supplicant_name);
}
Our problem was wrong supplicant name in prop setup. And, when wifi starts it first stops supplicant, and it wasn’t able to transfer that info through system. It was quite fun tracking this problem.
vim ./frameworks/base/wifi/java/android/net/wifi/WifiStateMachine.java
mWifiNative.killSupplicant(mP2pSupported);
if(mWifiNative.startSupplicant(mP2pSupported)) {
setWifiState(WIFI_STATE_ENABLING);
if (DBG) log("Supplicant start successful");
mWifiMonitor.startMonitoring();
transitionTo(mSupplicantStartingState);
} else {
loge("Failed to start supplicant!!");
}

Hi All,
I am working to bring up RealTeck USB wifi dongel on android 4.3 and kernel 3.0.35 below are steps I followed :
1) I am building drivers as modules, copying them to /system/lib/modules/ and after that I added below lines in init.rc before wpa_supplicant service start.
insmod /system/lib/modules/cfg80211.ko
insmod /system/lib/modules/mac80211.ko
insmod /system/lib/modules/rtlwifi.ko
insmod /system/lib/modules/rtl8192c-common.ko
insmod /system/lib/modules/rtl8192cu.ko
2)wlan0 interface is creating successfully in /sys/class/net/wlan0.
3) After that I try to run below commands :
root@sabresd_6dq:wpa_supplicant -Dnl80211 -iwlan0 -c/data/misc/wifi/wpa_supplicant.conf -dd -B ---> success
root@sabresd_6dq: wpa_cli ----> Able to scan the devices form command line .
But if I try to do from application I am getting below errors:

Zoran Lukic 2014-11-18 上午3:48 （回复 Ranganath tm）Hello Ranganath,
You need to run wpa_supplicant as service (in init.rc or init.xxxxx.rc script).
Do you need rf kill ?
We removed it completely from our android system.

Re: wifi binding on imx6sl evk based board
Zoran Lukic 2014-11-18 上午4:48 （回复 Ranganath tm）Are the service name and the name in the interface file same?
vim hardware/realtek/wlan/libhardware_legacy/wifi/wifi_realtek.c
static const char SUPPLICANT_NAME[] = "rtw_suppl"; /* without p2p concurrent */
and
in init.rc or init.xxxxx.rc script

-c/data/misc/wifi/wpa_supplicant.conf

class main

oneshot
You could add ALOGE to wifi_start_supplicant function, to get more debug data.
p2p is another service and interface.
Are the modules loaded ok, after booting?
Is the insert mod in the right place (you have on early-init, on boot, on fs), so maybe to make it as part of kernel, not modules, for start, to eliminate that.

Re: wifi binding on imx6sl evk based board
Ranganath tm 2014-11-18 上午5:27 （回复 Zoran Lukic）Hi Zoran,
Thanks for reply,
1) Yes services names are same inside init.freescale.rc and wifi_realtek.c, kindly find below :
static const char P2P_SUPPLICANT_NAME_REALTEK[] = "rtw_suppl_con"; /* p2p concurrent */
service rtw_suppl_con /system/bin/rtl_wpa_supplicant \
-iwlan0 -Dnl80211 -c/data/misc/wifi/wpa_supplicant.conf
class late_start
socket wpa_wlan0 dgram 660 wifi wifi
disabled
oneshot
2) I added logs inside function wifi_start_supplicant function and it pass below condition which give confidence supplicant is running,
if (pi != NULL) {
__system_property_read(pi, NULL, supp_status);
if (strcmp(supp_status, "running") == 0) {
ALOGE("TMR supplicant running success");
return 0;
}
3) Yes the modules are loading after boot in init.rc. Below is the result of lsmod,
rtl8192cu 91079 0 - Live 0x00000000
rtl8192c_common 54246 1 rtl8192cu, Live 0x00000000

4)But it fails in wifi_connect_on_socket_path function inside condition
ctrl_conn[index] = wpa_ctrl_open(path1);
if (ctrl_conn[index] == NULL) {
ALOGE("TMR wifi_connect_on_socket_path inside if");
ALOGE("Unable to open connection to supplicant on \"%s\": %s",
path, strerror(errno));

Re: wifi binding on imx6sl evk based board
Zoran Lukic 2014-11-18 上午6:42 （回复 Ranganath tm）This is P2P supplicant.
static const char P2P_SUPPLICANT_NAME_REALTEK[] = "rtw_suppl_con"; /* p2p concurrent */
or
static const char SUPPLICANT_NAME[] = "rtw_suppl"; /* without p2p concurrent */
Do you have rtw_suppl running on system?
I only have primary interface, not p2p (we dont need it)
root@shd_6sl:/ # ps | grep supp
wifi 2915 1 3108 1856 c00fdb8c 40191448 S /system/bin/wpa_supplicant
root@shd_6sl:/ # getprop |grep suppl
[init.svc.rtw_suppl]: [running]
Do you have this file in android fs:
/data/system/wpa_supplicant/wlan0 ?
I dont think this is correct path.
What is your wpa conf file, after you start wifi?
Mine is:
root@shd_6sl:/ # cat /data/misc/wifi/wpa_supplicant.conf
update_config=1
ctrl_interface=wlan0
eapol_version=1
ap_scan=1
fast_reauth=1
/* PRIMARY refers to the connection on the primary interface
* SECONDARY refers to an optional connection on a p2p interface */
Did you made modification so that jni (android_net_wifi_Wifi.cpp) can interface this driver?
vim frameworks/base/core/jni/android_net_wifi_Wifi.cpp
static jboolean android_net_wifi_killSupplicant(JNIEnv* env, jobject, jboolean p2pSupported)
{
return (jboolean)(::wifi_stop_supplicant(p2pSupported) == 0);
}
In 4.3 wifi_stop_supplicant function has argument:
int wifi_stop_supplicant(int p2p_supported);
also we have to add this (and some debug log):
vim hardware/realtek/wlan/libhardware_legacy/wifi/wifi_realtek.c
int wifi_stop_supplicant(int p2p_supported) {
.......
if (p2p_supported) {
property_get("wifi.supplicant", supplicant_name, P2P_SUPPLICANT_NAME);
snprintf(supplicant_prop_name, PROPERTY_KEY_MAX, P2P_PROP_NAME, supplicant_name);
ALOGE("p2p_supported wifi.supplicant=%s\n",supplicant_name);
} else {
property_get("wifi.supplicant", supplicant_name, SUPPLICANT_NAME);
snprintf(supplicant_prop_name, PROPERTY_KEY_MAX, SUPP_PROP_NAME, supplicant_name);
ALOGE("wifi.supplicant=%s\n",supplicant_name);
}
If you do not use modules for rtl wifi, remember to add return 0; in wifi_realtek.c functions:
insmod,rmmod,load_driver,wifi_load_driver,unload_driver,wifi_unload_driver.

In init.rc file, you have to setup correct permission, group and owner:
mkdir /system/etc/wifi 0770 wifi wifi
chmod 0770 /system/etc/wifi
chmod 0660 /system/etc/wifi/wpa_supplicant.conf
chown wifi wifi /system/etc/wifi/wpa_supplicant.conf

What is in the logcat?
Do you have this:
cat system/etc/permissions/required_hardware.xml | grep wifi
<feature name="android.hardware.wifi" />
there should be also android.hardware,wifi.direct or something like that. You could try it for now, without wifi.direct.
Edit file
vim ./frameworks/base/data/etc/platform.xml
or directly in android /system/etc/permissions/platform.xml and add those lines

Re: wifi binding on imx6sl evk based board
Zoran Lukic 2014-11-21 上午1:00 （回复 Ranganath tm）This means that android is working correctly:-).
As I said, couple messages before, wlan0 isnt in
/data/system/wpa_supplicant
I am not sure that there is even that directory.
In your wpa_supplicant.conf file, you set path to interface directory, but that path doesnt exist, and of course wlan0 file isnt there.
Please try with wpa_supplicant.conf that I've sent you before.

Ranganath tm 2014-11-21 上午5:00 （回复 Zoran Lukic）Hi Zoran,
When I execute by copying content of wpa_supplicant.conf as specified by you, I am not able to lunch wpa_supplicant below are errors,
rtl8192cu: MAC auto ON okay!
rtl8192cu: Tx queue select: 0x05
rtl8192c: Loading firmware file rtlwifi/rtl8192cufw.bin
ADDRCONF(NETDEV_UP): wlan0: link is not ready
mkdir[ctrl_interface]: Read-only file system
But if lunch wpa_supplicant in command, after that if I turn on my wiifi from settings app its working for me.
Zoran Kindly let me know where all the wpa-supplicant will stopped in HAL layer and who will the status of update init.svc.wpa_supplicant.

Could you pack this files/folders and send them to me. I will send you my email address in pm.

It is irrelevant, it just reports if process is running. Its a way to get info between layers in android.

Could you try without hub?
Have you build driver as modules? (remember return 0; for insmod in driver)
Could you add LOG to see what is the command?
