wl1271: ERROR sdio read failed (-110)

Hi,

Do you see this error only during calibration, or you see it even when turning on WLAN? Can you share the lsmod details?

Also, please check the below link and confirm if you have all the required changes in your board file
http://processors.wiki.ti.com/index.php/WL127x_Porting_Guide

Regards,
Gigi Joseph.

Hi Gigi,

I also face this error when i execute bellow command

ifconfig wlan0 hw ether 00:80:48:BA:d1:30 up

bellow is output of lsmod command

I already refereed mentioned link, and have changes in board file according it.

Hi,

Can you please also confirm if you are using the latest wl12xx driver/firmwares? 
The latest release is "ol_R5.SP7.01"

Regards,
Gigi Joseph.

Hi Gigi,

I am not able to find wl12xx driver/firmwares version but I am using firmware come along with IPNC_RDK.3.8

Hi,

You can identify the driver/firmware release by following the below instructions
http://processors.wiki.ti.com/index.php/WL12xx_NLCP_Driver_Debug

Please ensure that you are using the latest release...

Regards,
Gigi Joseph.

Hi Gigi,

I have build wl12xx driver with reference to following link

http://processors.wiki.ti.com/index.php/WL12xx_NLCP_Build_Instructions

After successful compilation when i boot my board with new wl12xx driver/firmware i get following boot logs

Hi,

ol_R5.SP4.01 is not the latest, but it should work.
Can you check if the connection and all is fine? Can you share your board file?

Hi Gigi,

There is connection problem on SDIO line which resolves above issue. Now I am able to calibrate and also able turn on wlan interface by

ifconfig wlan0 up

wl12xx: ERROR FW Assert Watchdog timeout
wl12xx: removing interface 00:0c:0c:a0:06:4c
ieee80211 phy0: Hardware restart was requested

what may be the problem?

Hi,

The below error:
"wl12xx: ERROR ELP wakeup timeout!"

suggests that the WLAN_IRQ line is not mapped correctly in your board file. Please ensure that...

Gigi Joseph.

Hi Gigi,

For interrupt line I have following configurations in my board file

Defining WLAN_IRQ gpio

#define GPIO_WLAN_IRQ    ((1 * 32) + 25)

Pinmux for WLAN_IRQ gpio

omap_mux_init_signal("gpio1_25", TI814X_INPUT_EN | TI814X_PULL_DIS);

Registering WLAN_IRQ in  wl12xx_platform_data structure

static struct wl12xx_platform_data wlan_data __initdata = {
    .irq = OMAP_GPIO_IRQ(GPIO_WLAN_IRQ),
    /* COM6 (127x) uses FREF */
    .board_ref_clock = WL12XX_REFCLOCK_38_XTAL,,
    .platform_quirks = WL12XX_PLATFORM_QUIRK_EDGE_IRQ,
};

Is these any thing wrong done by me in IRQ line mapping?

Hi Chetan,

Sorry for the late response...
If it is still relevant, can you enable the DEBUG_IRQ driver logs and send me the logs. I can verify if you are getting any interrupts from the WLAN chipset.

To enable DEBUG_IRQ logs,
echo 256 > /sys/module/wl12xx/parameters/debug_level

Gigi Joseph.

Hi Gigi,

I have compiled latest wifi modules and used it with my board, from log i can see versions as follow

Compat-wireless backport release: ol_R5.SP4.01

Backport based on wl12xx.git ol_R5.SP7.01

Firmware virsion : Rev 6.3.10.0.139

when i am trying to do ifconfig wlan0 up i get following error

wl12xx: state: 0
wavu_dbg: wl12xx_set_power reseting
wl12xx: ERROR timeout waiting for the hardware to complete initialization
