WL1271 "ELP wakeup timeout" on scan

Hi everyone,

I am facing issue with WL1271 module by LSR TiWi-R2 on my custom board using DM8168... I am using wlan build scripts for building module, firmware and other utilities. Wlan is getting powered on and I get a message firmware is booted, but when i do scan, I get error saying ELP wakeup timeout and then a crash message comes.

Here is my command sequence:

------------------------------------------------------------

root@dm816x-evm:~# ifconfig wlan0 down
root@dm816x-evm:~# ifconfig wlan0 hw ether de:ad:be:ef:c0:fe

    Hello Ajay:

       I also have the problem of ELP wakeup_timeout , could you tell me the correct configuration of your wlan IRQ pin.

      My IRQ is as following:  

    gpio-39  (gpio1_07_mux1       ) in  lo irq-199 edge-rising

     interrupt as following:

    199:          0        GPIO  wl1271

    Hello Ajay:

       I also have the problem of ELP wakeup_timeout , could you tell me the correct configuration of your wlan IRQ pin.

      My IRQ is as following:  

    gpio-39  (gpio1_07_mux1       ) in  lo irq-199 edge-rising

     interrupt as following:

    199:          0        GPIO  wl1271

    Hi,

     

    As the driver boots up and loades the firmware it looks like your SDIO interace is working ok.

    My guess is that after the firmware is loaded (process which is not using interrupts from the module), and the driver start interacting with the module, it is not getting any interrupts from the wl12xx which cause a recovery.

     

    As the wl12xx interrupts are using a GPIO, please make sure that you have muxed it correctly and configured it as an input.

     

    You check  /proc/interrupts and verify whether the wl12xx interrupt line recived any interrupt.

     

    Best Regards,

    Eyal Reizer

    Could tell me the website of wl1271 compat-driver that you use.

    Hi Quan,

    You can use build script available on following wiki page to download and build wlan drivers and other related softwares.

    Hi Experts,

    I am using my custom board.

    Here "PCA9554PW,118" i2c expander is connected with the GPIO PIN (3,3) of AM335X processor. And GPIO_WL_IRQ is connected to the P1 pin of I2c Expander. Here how can i pinmux for WL IRQ?

    1. I getting some error while connect to the wifi (even IP is not assigned for my wlan0 interface)

    2. If interrupt pin is the only problem then. how to solved this issue?

    Thanks,

    Murugesan,

     

    Please check the following:

    1. in the board file (board-am335xevm.c) have you modified the wl12xx_platform_data structure ".irq" fielld with the modified GPIO number that you are using?

    struct wl12xx_platform_data am335xevm_wlan_data = {
     .irq = OMAP_GPIO_IRQ(AM335XEVM_WLAN_IRQ_GPIO),
     .board_ref_clock = WL12XX_REFCLOCK_38_XTAL, /* 38.4Mhz */
     .bt_enable_gpio = GPIO_TO_PIN(3, 21),
     .wlan_enable_gpio = GPIO_TO_PIN(1, 16),
    };

    2. When doing "cat /proc/interrupts" are you seeing that the number of "wl12xx" interrupts is increasing?

    root@am335x-evm:~# cat /proc/interrupts

    ...

    ...

    273:         50      GPIO  wl12xx

    3. If you do "iw wlan0 scan" are you getting scan results, or do you see a recovery?

     

    Best Regards,

    Hi Eyal Reizer,

    1.Yes we do

    #define WLAN_IRQ 129
    struct wl12xx_platform_data am335xevm_wlan_data = {
    .irq = OMAP_GPIO_IRQ(WLAN_IRQ),
    .board_ref_clock = WL12XX_REFCLOCK_38_XTAL, /* 38.4Mhz */
    .bt_enable_gpio = GPIO_TO_PIN(1, 30),
    .wlan_enable_gpio = GPIO_TO_PIN(1, 9),
    };

    3. If we do "iw wlan0 scan" i got the same recovery message from the console.

    FYI:-

    Connected more that one devices on I2C expander:

    And I2c Expander INT pin is connected to GPIO(3,3) of Processor AM3354

    We connected below device INT/IRQ pin to I2c expander i/o ports.

    GPIO HDMI INT--> P0

    GPIO WLAN IRQ --> P1

    GPIO Ecompass INT --> P4

    Can you please give some suggession to solve the Wifi issue.

    Thanks,

    As I see from the logs, interrupt is not getting generated. I think you need to look into your IO Expander why its not sending interrupts to SOC.

    Anything do i need to add in am335x board code in IO Expander?. If so Can you help us the IO Expander code level program.

    Since IO Expander interrupt pin is connected with GPIO (3,3), but All the device connected to the IO expander will generate the INT/IRQ. So how to find out which device generate the INT/IRQ using IO expander GPIO (3,3)?

    Please help me to solve this problem.

    Thanks,
