Support RTL8188 8192 wifi dongle in FSL JB4.2.2-GA release

1 Kudo

Development environment

Hardware: i.MX6Q SabreSD connecting rtl8188cus or rtl8192cus wifi dongle

Software: FSL JB 4.2.2-1.1.0-GA release

Advantage brought by JB4.2.2

As we may know that in JB4.0.x, Wifi-Direct is exclusive to normal Wifi access AP, so means that you have to turn off Wifi normal AP access, then turn on Wifi-Direct. But in JB4.2.x, it can support the following topologies in use scene as following:

So that means you can keep p2p connection meanwhile access internet throught AP.

Feature verified

1. Wifi connection support internet surf, and DLNA.

2. Wifi-Direct can support files transmission like Gallery sharing based on Wifi-Direct Demo.apk from FSL.

3. Particial support Wifi-Display, but due to unavailability of Wifi-Display sink module, so cannot be verified fully.

Usage:

untar the attached file, then "patch -p1 <" in corresponding subdirectories. It would be better to untar the file in an empty directory, so you can understand which subdirectories are newly created (ex. hardware/realtek is newly created), then within these newly created subdirectoies, you need to "git init" first, then do "patch -p1<" to adopt all newly added files and subdirectories.

Original Attachment has been moved to: WiFiDirectDemo.apk.zip

Dear Xia Zhang

We are using your patch :

Support RTL8188 8192 wifi dongle in FSL JB4.2.2-G...

To use 8188 CUS, after make the patch.

And load the cfg80211.ko ,mac80211.ko and 8192cu.ko,

But still can not use the WiFi on JB4.2.2

Here is the error message:

Hi, Steven,

Your log messages show that you still use Atheros, not realtek. Pls check whehter you correctly merge the code in devices/fsl directory. I use sabresd_6dq-user. Do you use the same target board?

Regards,

Alan Zhang

steven1758 · ‎08-05-2013

Dear Xia Zhang

Thank you very much for your reply.

Just have found this too.

In device/fsl/sabresd_6dq/BoardConfig.mk is still the Atheros one

This patch patch4rtl8188_8192_on_jb4_2_2-ga\device\fsl\0001-Adopt-rtl8188-rtl8192-usb-dongle-support.patch does not work.

excute like this

~myandroid/device/fsl$ patch -p1 < patch4rtl8188_8192_on_jb4_2_2-ga\device\fsl\0001-Adopt-rtl8188-rtl8192-usb-dongle-support.patch

But nothing changes. : (

Can you help me how to make this patch . : )

Thanks

Kind Regards

steven

AlanZhang · ‎08-05-2013

Pls check your directory's attribute whether they are read-only! Also check "patch" command works or not. The patch file (devices/fsl/) contains all necessary modification inside, you can open it and check.

Alan Zhang

steven1758 · ‎08-05-2013

Dear Xia Zhang

Thanks for your reply.

The directory's attribute all is ok: as you can see here.

I am sure that the patch file (devices/fsl/) does not work, the file in (device/fsl) folder still the older one.

Dear Xia Zhang

After manual patch devices/fsl/ folder ,all is ok now. : )

Thanks again for your help.

I have a boundary devices sabrelite board and applied your patches to the jb source code for this board. Eveything besides board-specific patches (i.e. in drivers/fsl) worked. I then manually patched the board specific files. When I try to build, I get the following error:

Dear Xia Zhang,

We are using this patch for implementing "Wi-FI Direct" but we have a issue about p2p.

The operation for STA mode is Ok but the problem occur when target find other p2p device.

after debugging along with source code, I find that "p2p_find" function is not called in "wpas_p2p_find", "P2_supplicant.c" because "wpa_s->global->p2p" is null.

Could you give some advice for solving this problem? And then Where should I check any part of "wpa_supplicant" part?

Actually I am working with wifi-module firstly, so I have a less knowledge about this.

I am wating for your reply. let me know what you need if you need something for checking this issue.

Thank you. Best regards. from Cloud.

I gone through your patches and this patches works for ath6k series chips. i'm using ath9k series atheros chips, which uses PCIe interface. the respective driver creates wlan0 interface in driver level and i want use create p2p0 interface and want to UP both the interface and use concurrently, do you have any idea how i can do it.

I tried following steps to create p2p0 interface from user space but fail to assign MAC address to P2p0 interface.

https://community.freescale.com/message/388240#388240

Kind;y give me your inputs regarding this.

thanks in advance.
