wl12xx: WARNING unsupported chip id: 0x0

Girish Buhalli

Other Parts Discussed in Thread: WL1271, SYSCONFIG, AM3505

Hi,

We are back porting wl12xx drivers from latest Compat Wireless package to my Kernel. My kernel version is 2.6.28.2. and platform is NXP LPC313X. We have interfaced WL1271 through SDIO(MMC slot 0)

I always get the "wl12xx: WARNING unsupported chip id: 0x0" error when I run the following command "ifconfig wlan0 up".

My sdio write/read operations are successful.

The log from console

We have done the necessary modifications to load the all the compat wireless related KOs ( compat.ko, rfkill_backport.ko, cfg80211.ko, mac80211.ko, wl12xx.ko and wl12xx_sdio.ko)

The following modifications to sucessfully load the modules

1. Disable all SDIO power management functions in Compat wireless drivers because the our kernel doesn't support SDIO/MMC run time power management functions

2. Modified the check to "if (func->num != 0x01)" from "if (func->num != 0x02)" in wl1271_probe() functions of sdio.c(/compat-wireless-2012-02-26/drivers/net/wireless/wl12xx/sdio.c)

3. The name was modified from "wl12xx_driver" to "wl12xx" in main.c

   static struct platform_driver wl12xx_driver = {
   .probe       = wl12xx_probe,
   .remove       = __devexit_p(wl12xx_remove),
#if LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,30)
   .id_table   = wl12xx_id_table,
#endif
   .driver = {
   //   .name   = "wl12xx_driver",
       .name   = "wl12xx",
       .owner   = THIS_MODULE,
   }
};\

With the above changes my wl12xx_probe() is being called successfully.

We had issues with writing to "W_ACCESS_ELP_CTRL_REG_ADDR" using "sdio_f0_writeb()" function. We used to error as (-22) EINVAL always for this register

Now we have replaced the "sdio_f0_writeb" & sdio_f0_readb" functions with "sdio_writeb" and "sdio_writeb" and "sdio_readb". now we don't see any sdio read/write failuers.

But the chip id is not being read properly and due to this firmware is not loaded.

Please let us know any suggestions on this

Thanks

Hi Girish,

lookint the kernel code it is possible to replace the "sdio_f0_writeb" & sdio_f0_readb" functions with "sdio_writeb" and "sdio_writeb" and "sdio_readb". assuming you had set the func->num to 0 in functions sdio_writeb" and "sdio_readb".

please confirm that you had done that correctly

see reference for the functions:

void sdio_writeb(struct sdio_func *func, u8 b, unsigned int addr, int *err_ret)

398 {

399         int ret;

401         BUG_ON(!func);

403         ret = mmc_io_rw_direct(func->card, 1, func->num, addr, b, NULL);

404         if (err_ret)

405                 *err_ret = ret;

406 }

void sdio_f0_writeb(struct sdio_func *func, unsigned char b, unsigned int addr,

657         int *err_ret)

658 {

659         int ret;

661         BUG_ON(!func);

663         if ((addr < 0xF0 || addr > 0xFF) && (!mmc_card_lenient_fn0(func->card))) {

664                 if (err_ret)

665                         *err_ret = -EINVAL;

666                 return;

667         }

669         ret = mmc_io_rw_direct(func->card, 1, 0, addr, b, NULL);

670         if (err_ret)

671                 *err_ret = ret;

672 }

Eyal

Hi Eyal,

Thanks fir the reply.

I want to clarify here that I am not explicitly setting the func->num to 0 in functions sdio_writeb" and "sdio_readb". These functions are implemented in Linux-2.6.28.2/drivers/mmc/core_sdio_io.c.

I read the value of func-num as 0x1, which we guess is not correct.

I had backported the mmc stack from Linux-2.6.32 and currently I am able to use the sdio_f0_writeb and sdio_writeb functions itself.

Now the issue I am facing is the WL1271 chip id is always read as 0x0. The reason I suspect is the issue with struct sdio_func *func->num,

The Wi-FI interface in WL1271 can work with function number 0x2, however, when I load the wl12xx_sdio.ko, I get the func->num = 0x01, Which could a reason why I fail.

My system log when the mmc platform driver loaded is as follows

mmc0: card claims to support voltages below the defined range. These will be ignored.
mmc0: queuing CIS tuple 0x91 length 3
mmc0: new SDIO card at address 0001

I am new to Linux and SDIO stack. Let me the mistake I am committing here

Thanks

Hi Girish,

The logs that you got are good, it indicates that the Linux kernel had probed the SDIO and completed the negotiation with it

mmc0: card claims to support voltages below the defined range. These will be ignored.
mmc0: queuing CIS tuple 0x91 length 3
mmc0: new SDIO card at address 0001

However if you will not keep func->num to 0 then the SDIO read write transactions will not be to the right place and that could explain why the chip ID is read as 0

Hi Girish,

Would like to touch base on the issue, were you able to have progress with that?

Hi Eyal,

Sorry for not replying on the progress made

We are able to make resolve the issue with reading the WL1271 chip ID. Now we are reading the chip ID as 0x4030111.

The issue is with powering-on the Bluetooth while loading the kernel. Due to this kernel was passing the function number as 0x1 and the wl12xx driver used to read/write the memory area of function 1(Bluetooth). Now after disabling the powering-on of Bluetooth and explicitly returning from wl1271_probe() for function other than 0x2, the driver will be accessing the memory are of Wi-Fi.

Still we are not sure why we should keep the BT powered-down while system booting.

We are able to load of all the Compat Wireless Modules, ifconfig wlan0 operations to assign the Mac address and starting the wlan0 interface.

With Compat Wireless -2012-02-22 and Firmware ver 03 - wl127x-fw-3.bin, and after applying the patches, we are able to get the interface up and able to connect in open mode.

http://permalink.gmane.org/gmane.linux.kernel.wireless.general/84311

http://permalink.gmane.org/gmane.linux.kernel.wireless.general/84312

However the calibration is not successful.

I am running the following command

./calibrator plt autocalibrate wlan0 /tmp/wl12xx_sdio.ko /lib/firmware/ti-connectivity/ini_files/TQS_S_2.6.ini /lib/firmware/ti-connectivity/wl1271-nvs.bin 00:01:02:03:65:29

With latest Compat wireless package (2012-04-03) and firmware ver (04 - wl127x-fw-4-sr.bin and wl127x-fw-4-plt.bin, ) I am able to successfully calibrate and nvs file sucessfully.

However, I am not able to connect to any device. there is crash in the modules. However I am able to do the scan operation successfully.

There is crash after running the following commands

ifconfig wlan0 down &
ifconfig wlan0 hw ether de:ad:be:ef:c0:fe &
iwconfig wlan0 mode ad-hoc
iwconfig wlan0 essid brady123
ifconfig wlan0 192.168.1.6 up

Please find the log below

Let us know the right version of the firmware and Compat Wireless package to be used for both calibration and successful operation

Hi,

From your log it looks like youare trying to work in IBSS mode.

The commands you are using (using iwconfig) are a bit obsolete (iwconfig is not fully supported any longer).

Please try the sequence as in the below link and let us know if it works better:

"Let us know the right version of the firmware and Compat Wireless package to be used for both calibration and successful operation" +1

I asked it ~month before. But no one answered.

Hi Petrov,

Can you please explain why were your question not answered? Please get in the links you have in the e2e that you mentioned, there are build instructions for WLAN with links to the Compat that we are using and for the firmware’s that matches o that Compat.

Maybe what is confusing that as far as our Catalog offering (SDK releases) we provide Comapt and firmware that was tested by us and not the one that you get from the open source.

For example if you go to link http://processors.wiki.ti.com/index.php/OMAP_Wireless_Connectivity_OpenSource_WLAN_release_R4SP2_Engineering_Drop

You can see that the Compat is from:

WLAN Driver & Firmware - Build the TI compat-wireless package

Download the compat-wireless package from <R4SP2 Compat wireless> location
Extract the compat wireless zip file to your PC

And firmware is from:

Download and install the wl12xx Firmware Files

Clone the firmware git (same git is used for hostapd and WPA supplicant):

git clone git://github.com/TI-OpenLink/ti-utils.git

Point to the specific Commit ID (d8513c2c8dfa1913e51f2b12436a4bbebc470064):

git reset --hard d8513c2c8dfa1913e51f2b12436a4bbebc470064

Copy the firmware files to the EVM under the /lib/firmware/ti-connectivity directory in your root file system.

Regards,

Eyal

It's OK Eyal, sorry for that. There are a lot of versions, patches, files and so on.... it's very simply to make a mistake. Your information almost correct ).

Hi Girish,

Do you still have an issue with the IBSS?

Hi Petrov,

You are right, it is very confusing, for that reason we are releasing SDK so customers will be able to get some order in it

Hi Eyal,

Currently we are not trying with latest Compat Wireless package.

As the Compat Wireless-2012-02-22 (with WL1271 Firmware Rev 6.3.0.0.77) works fine for us except issue with autocalibration, we are using the same for further Wi-Fi direct verification for product.

The only issue with that version is the calibrated wl1271-nvs.bin file size is only 503 bytes instead of 912 bytes

Let you know if any issues once we try the latest Compat Wireless package

Thanks

Girish

TI__Genius 9240 points

Hi,

In case the wl1271-nvs.bin is wrong size (should be 912 bytes) then the WLAN driver will not even go up and WLAN will not work at all, so I would first like to know if you are able to bring up the WLAN, perform scan and connect to AP.

In addition the wl1271-nvs.bin is a product of the Calibration process (although there is one provided in the file system), so could you please send me the Calibration process you do and the terminal logs? (i ssume it is different than the log you provided earlier) I would like to understand if the process also the ini file that you had used.

Regards,

Eyal

Hello eyal,

I am also back porting wl12xx to my kernel (modified version of TI's linux-03.00.01.06 kernel for AM3517EVM kernel) and platform is AM3505. We have interfaced WL1271 through SDIO (MMC slot 0).

I am able to load sdio based modules of Compat Wireless package 2.6.37. With this I am able to up the wlan0 interface using ifconfig wlan0 up when PM_RUNTIME is disabled and i can scan and connect to Access Point successfully. But as i want to run calibrator utility i need to power it down, up, down and so on. So must enable PM_RUNTIME in my kernel.

Please let me know whether PM_RUNTIME is available for this kernel linux-03.00.01.0 ( which is 2.6.32 baseline kernel, if i am not wrong). And please give me direction if it is not available in this kernel. I already tried the patches given on the wireless community and i am failed to apply those patches as it seems some files should be in my kernel and which is not in my kernel.

My end goal is to run calibrator utility and hence i selected Compat wireless package 2.6.37.

Regards,

Hitesh V.

Hi,

With PM_RUNTIME disabled have you tried doing ifconfig wlan0 down/up and made sure it is not working?

If this is the case then you may be able to write a custom power_on function and pass to mmc[1].dev->platform_data->slots[0].set_power = wl12xx_set_power.

This function would then be called when you up/down the driver and you can explicitly control the WLAN reset pin from it:

Please refer to the following link:
