omap4470 with Wlink6

Hello,

You should follow all the steps described in 4AJ2.5P2 Release notes in order to build your MLO, u-boot, kernel & AFS.

When executing the http://omappedia.org/wiki/4AJ.2.2_OMAP4_Jelly_Bean_Panda_Notes#Building_WLAN_driver

AND prepare the android binaries by following: http://omappedia.org/wiki/4AJ.2.2_OMAP4_Jelly_Bean_Panda_Notes#Preparing_Android_binaries

You should flash your device & after that execute (on your platform):

# su

# wilink7.sh

In order to make Android work with WiLink7.

Best Regards,
Yordan

Dear Yordan

I appreciate your quickly reply, and I have one thing need to clarify.

   wl127X is belong with WiLink6 like this  http://processors.wiki.ti.com/index.php/WL127x

    Does WLan driver from http://omappedia.org/wiki/4AJ.2.2_OMAP4_Jelly_Bean_Panda_Notes#Building_WLAN_driver is   WiLink6?

     It is said that WiLink7 (wl1283) from http://omappedia.org/wiki/Android_Mac80211#WLAN_Calibration_Instruction

but our chipset is wl1721

Hello,

The WLAN driver from 4AJ.2.2 Release Notes, that you refer to, is WiLink7 driver.

But I think it should work with your chip as well. Or with slight modifications to the script.

The script itself removes all WiLink 8 modules from /system/lib/modules. And then copies the WiLink 7 modules (located in /system/lib/modules/wl7) in the /system/lib/modules folder as folllows:

 # Copy WL7 modules
ln -s $WL7_MODULES_PATH/cfg80211.ko $MODULES_PATH/cfg80211.ko
chmod 644 $MODULES_PATH/cfg80211.ko
ln -s $WL7_MODULES_PATH/mac80211.ko $MODULES_PATH/mac80211.ko
chmod 644 $MODULES_PATH/mac80211.ko
ln -s $WL7_MODULES_PATH/wl12xx.ko $MODULES_PATH/wl12xx.ko
chmod 644 $MODULES_PATH/wl12xx.ko
ln -s $WL7_MODULES_PATH/wl12xx_sdio.ko $MODULES_PATH/wlcore_sdio.ko
chmod 644 $MODULES_PATH/wlcore_sdio.ko
sleep 2
sync

So a slight modification to that script should get it to work with your wl1721 module.

Best Regards,
Yordan

Hi Yordan

Sorry. I don't know what you mean about " a slight modification to that script ". wilink7.sh?  I will appreciate if you provide me  further hints. According to your inform,  the source code of compat_12xx in 4AJ2.2 is same with compat_12xx in 4AJ2.5P2? 

We use Wilink7 driver refer to 4AJ.2.5P2 Release and print the log attached. It seems that it doesn't recognize  the  HW.

so I guess that driver doesn't work on wl1721 chipset

Hi,

All Android releases for OMAP4 devices use WiLink7 or WiLink8 (by default 4AJ2.5 uses WiLink8, hence it needs to be configured to work with WiLink7 if your hardware platform uses wl128x chip).

You use wl1721 chip, right (I haven't worked with this wi fi module; official ti platforms use WiLink7 & WiLink8)? It does not belong to WiLink 7 or WiLink 8 family of wireless chips. That is why 4AJ2.5 log shows "wl12xx: ERROR could't get hw info" .

You need to build the sources for your wl1721 chip. Steps should be similar as in the release notes & the build will produce similar outputs (the highlighted, in yellow, names should be different, to reference the wl17xx chip) : compat.ko, cfg80211.ko, mac80211.ko, wl18xx.ko, wlcore.ko, wl12xx.ko and wl17xx_sdio.ko 

Once you have your wl17xx object files built you need to: 
1. copy them in system/lib/modules/wl7/

2. modify the wilink7.sh script to link your wl17xx object files to  /system/lib/modules/ folder, by changing the names of the .ko files in  $WL7_MODULES_PATH/ (highlighted bellow): 

 # Copy WL7 modules
ln -s $WL7_MODULES_PATH/cfg80211.ko $MODULES_PATH/cfg80211.ko
chmod 644 $MODULES_PATH/cfg80211.ko
ln -s $WL7_MODULES_PATH/mac80211.ko $MODULES_PATH/mac80211.ko
chmod 644 $MODULES_PATH/mac80211.ko
ln -s $WL7_MODULES_PATH/wl12xx.ko $MODULES_PATH/wl12xx.ko
chmod 644 $MODULES_PATH/wl12xx.ko
ln -s $WL7_MODULES_PATH/wl12xx_sdio.ko $MODULES_PATH/wlcore_sdio.ko
chmod 644 $MODULES_PATH/wlcore_sdio.ko
sleep 2
sync

Best Regards,

Yordan

Dear Yordan

I'm sorry, all of my fault.

We use wl1271 chipset not wl17XX, so  I think wilink7.sh doesn't need to be modified.

We adapt your suggestion that you think WiLink7 driver can work on wl127x, and we find wg7311-2A(We use

wg7311-0A)porting guide http://59.124.231.13/index.php/WG7311_Driver_for_OMAP4.

Thus, we build WLan7 source from 4AJ2.5P2, and the log is below

Hello Bernie,

I looked at the code in /home/users/ykovachev/blaze_4460/4AJ.2.2/kernel/android-3.0/drivers/net/wireless/wl12xx, and the source files seem to support the wl1271 chip. 

Could you please check your board file to see which wifi chip it references? Maybe you haven't modified it & it still uses the wl128x device.

Maybe this is why you get an error, when you try to enable the wilink7 by wilink7.sh script & modifications described in: http://59.124.231.13/index.php/WG7311_Driver_for_OMAP4

Best Regards,

Yordan

Hello Yordan

We toward the message of "wl1271_sdio mmc2:0001:2: sdio write failed (-110)" to fix.And we have referenced wl1271 porting guide.  Can you give me some further advice?

I trace the code in board-44xx-54xx-connectivity.c find some thing weird.

static struct regulator_init_data omap4plus_vmmc_regulator = {
        .constraints            = {
        .valid_ops_mask = REGULATOR_CHANGE_STATUS,
    },
    .num_consumer_supplies  = 1,
    .consumer_supplies      = &omap5_evm_vmmc3_supply,  <-- does it should be &omap4_vmmc5_supply replaced?
                                                                                                      we are using omap4470. 
};

thank you

Hi,

This depends on how your wilink chip is connected on the board. If it interfaces with mmc5, then yes.

Since I cannot test this on my side, because you are using a custom board, I suggest you have a look at the configuration for omap4 panda board (files are available in android sources), it uses wl1271 chips for wireless connection (refer to pandaboard board file, and make modifications to the board file you use).

Best Regards,

Yordan

Hi Yordan

Thanks your quickly reply, I am just researching Panda. But I need your help,thanks.

1  Is there the difference between  &omap5_evm_vmmc3_supply and &omap4_vmmc5_supply just interface mmc3 or  mm5? what about omap4 and omap5?

2  If I use 4AJ2.2 source code, does it work that I change 4AJ2.5P2

    mydroid/hardware/ti/wlan/mac80211/compat_wl12xx  to the other form 4AJ2.2, and build them with steps from

    4AJ2.5P2?

    Thank you very much

     BestRegards

     Benrie 

Hello Bernie,

Regarding your questions:
 

 1. You should change that to &omap4_vmmc5_supply, because OMAP4 devices use MMC5 to interface with wifi chips, while OMAP5 devices use MMC3 (you can check this in pandaboard schematics & Figure 1-1. OMAP4470 High-Tier Environment of OMAP4470 TRM) . So you should use &omap4_vmmc5_supply.

 2. I think both releases contain drivers for wl1271 chips. So it should be ok to replace them & build using the steps from release notes.

It also shouldn't be a problem to use the 4AJ2.5 source & enable the wl1271 drivers inside it.

Best Regards,
Yordan

Good!  I've attached  Panda patch on my code, and got the same problem.

cat  sys/bus/mmc/devices--> mmc0:0001

                                              mmc2:0001

cat sys/bus/mmc/devices/mmc2:0001/type -> SDIO

cat sys/bus/mmc/devices/mmc2:0001/runtime_status -> suspended

So,our aim is make mmc5 appear on device? 

 BestRegards

Hello Bernie,

Have you tried adding the TQS_S_2.6.ini file in /system/etc/wifi/TQS_S_2.6.in and then execute the calibration procedure for WL1271 chip, as described here: http://omappedia.org/wiki/Android_Mac80211#WLAN_Calibration_Instruction

Best Regards,

Yordan

Hi Yordan

First,I very appreciate you concerning this issue.

According to the website you give me, I do some steps below

1 mount -o remount rw /system
2 rm /system/etc/firmware/ti-connectivity/wl1271-nvs.bin
3 export TARGET_FW_DIR=/system/etc/firmware/ti-connectivity
4 export TARGET_NVS_FILE=$TARGET_FW_DIR/wl1271-nvs.bin
5 export WL12xx_MODULE=/system/lib/modules/wl12xx_sdio.ko
6 export TARGET_INI_FILE=/system/etc/wifi/TQS_S_2.6.ini
7 calibrator plt autocalibrate wlan0 $WL12xx_MODULE $TARGET_INI_FILE $TARGET_NVS_FILE

show

insmod: can't open '/system/lib/modules/wl12xx_sdio.ko'
Failed to load kernel module using command /system/bin/insmod /system/lib/modules/wl12xx_sdio.ko
Calibration not complete. Removing half-baked nvs

I think we must enable the wifi that it can find AP around first and than do calibrate 


BestRegards

Hello Bernie,

A couple of ideas, after reading some similar issues on wl1271 in the WiLink™ WiFi + Bluetooth Forum http://e2e.ti.com/support/wireless_connectivity/f/307.aspx (I think it is a good idea to post there as well, since someone may have already encountered that problem and propose a solution faster):

 1. Can you verify that your WLAN_EN line is toggling? Check your schematics, the WLAN_EN signal should be connected to a GPIO.

2. Double check the MMC configurations (pin mux, clocking). Having a look at the configurations in your previous post  I see you've taken care of pin mux & power supply, but how about MMC5 clocking?

Best Regards,
Yordan

Hi Yordan

I will check your recommend later. But I have another question, Does calibration steps after doing  wilink7.sh or before ?

Thank you very much.

As far as I remember, when working on blaze, I ran the wilink7.sh script first and then executed the calibration steps. But looking at the instruction I don't see a requirement to run the wilink7.sh script first, so I guess both are possible.

Regards,

Yordan

The problem had solved, that because mmc2 vdd doesn't have voltage enough  . Thank you.

Glad to hear that. Thanks for posting the solution to your case.

Best Regards,
Yordan
