Hi all,

My android source code built successfully and i am able to connect to an AP with my wifi module through terminal.I have to do with GUI.When i am turning on the wifi on screen supplicant is not running.I made changes in init.rc file in out/target/product/evk6sl/root/init.rc but it was not including the changes that i did in that file.Please share if any one knows how to run the supplicant through GUI automatically. Waiting for positive and fast reply.Please help me in getting out of this.

Hi Saurabh,

Thanks for the reply.I am very new to android and i think i am doing well with your help.

I added a few changes in the init.rc wherein I try to start the supplicant. The following are the changes:

service wpa_supplicant /system/bin/wpa_supplicant -iwifi0 -Dnl80211 -c \

/system/bin/release/sta_settings.conf -dd

class main

socket wpa_wifi0 dgram 0660 wifi wifi

group wifi system

disabled

oneshot

I do this change in the file init.rc present in the path /myandroid/out/target/product/evk_6sl/root/

I then do a make snod, make. I even tried make bootimage. Having done this, I flashed the images on the SD memory card. After having booted with the sd card, I then check the init.rc file. The init.rc doesn't have the changes that I made. Firstly, how do I ensure that the changes I made in init.rc are actually reflected in the final bootimage.

I will send across the logcat output as well. Another issue is I get the option to turn on wifi from Android->Settings. I am unable to turn off WiFi at all. Is there something to do with my driver or where can I find control to turn off Wifi?

What hardware you are using? And what build command is used?

For full built i am using

1) source build/envsetup.sh

2) lunch evk_6sl-user 3) make 2>&1 | tee build_evk_6sl_android.log

Thank you,

Mutyala Rao.

Hi,

init.rc is in boot.img. So I think you can delete all of the boot*.img and ramdisk* in out folder. Then use " mm bootimage -B" command to build the boot image again.

Thanks.

Hi,

Delete all of *.img is not necessary. In fact "mm bootimage -B" will always rebuild the boot.img. So you can simply use "mm bootimage -B".

Besides make sure you are editing the correct init.rc as we have some board specific folder in device/fsl.

Thanks.

Can you please let me know which init.rc is to be modified.. the one in out/target/product/evk_6sl/root/ or the one in device/fsl/evk_6sl?

Hi,

Please do not edit the init.rc in out/target/product/evk_6sl. It will be refresh when compile and it will be in vain.

Please edit the init.rc in device/fsl/evk_6sl/.

Then "mm bootimage -B".

Thanks.

Hi,

Glad to see progress were made.I suggest to mark this topic as "Answered". And post your logcat with the wifi scanning issue to a new topic.

Then more experts will see your issue and help to solve the issue.

Thanks.
