WL1285Q WiFi porting problem

One more question,
When wl12xx_set_platform_data() is used that of drivers/net/wireless/wl12xx/wl12xx_platform_data.c?
Not the one in the driver what we created by compat-wireless.

Hi,

Which AM335x SDK are you using?
Have you also added the board_tcxo_clock entry in the wl12xx_platform_data structure?
What are the values of board_tcxo_clock/board_ref_clock that you are using?

Can you confirm that the WLAN_EN is indeed going high (with a scope)?

The porting guide is available at: http://processors.wiki.ti.com/index.php/WL127x_Porting_Guide

Also, wl128x_switch_tcxo_to_fref() returns '0' on success.

I did not understand your other query regarding: wl12xx_set_platform_data() . The one in the compat-wireless should be invoked. Your kernel ".config" should only have CONFIG_WL12XX_PLATFORM_DATA set.

Regards,
Gigi Joseph.

1. SDK is 05.05, you can download it from the link in previous message.

2. here is platfrom data for wl12xx

struct wl12xx_platform_data am335xevm_wlan_data = {                 .irq = OMAP_GPIO_IRQ(AM335XEVM_WLAN_IRQ_GPIO),                 .board_ref_clock = WL12XX_REFCLOCK_26_XTAL, /* 38.4Mhz */                 .board_tcxo_clock = WL12XX_TCXOCLOCK_26, /* 26 MHz */                 .bt_enable_gpio = GPIO_TO_PIN(3, 21),                 .wlan_enable_gpio = GPIO_TO_PIN(0, 22), /* wifi- enable */ };

 3. WLAN_EN is working

4. "wl128x_switch_tcxo_to_fref()" returns zero, then "wl128x_boot_clk()" return "-EINVAL".

int wl128x_boot_clk(struct wl1271 *wl, int *selected_clock) {                 u16 sys_clk_cfg;                 int ret;                   printk("wl128x_boot_clk\n");                 /* For XTAL-only modes, FREF will be used after switching from TCXO */                 if (wl->ref_clock == WL12XX_REFCLOCK_26_XTAL ||                     wl->ref_clock == WL12XX_REFCLOCK_38_XTAL) {                                 printk("wl->ref_clock=%d\n", wl->ref_clock);                                 if (!wl128x_switch_tcxo_to_fref(wl)){                                                 printk("wl128x_switch_tcxo_to_fref return zero...\n");                                                 return -EINVAL;                                 }                                 goto fref_clk;                 }                 /* Query the HW, to determine which clock source we should use */                 ret = wl1271_top_reg_read(wl, SYS_CLK_CFG_REG, &sys_clk_cfg);                 printk("wl1271_top_reg_read[%d]\n", ret);                 if (ret < 0)                                 return ret;                 if (sys_clk_cfg == 0xFFFF)                                 return -EINVAL;                 if (sys_clk_cfg & PRCM_CM_EN_MUX_WLAN_FREF)                                 goto fref_clk;                 /* If TCXO is either 32.736MHz or 16.368MHz, switch to FREF */                 if (wl->tcxo_clock == WL12XX_TCXOCLOCK_16_368 ||                     wl->tcxo_clock == WL12XX_TCXOCLOCK_32_736) {                                 if (!wl128x_switch_tcxo_to_fref(wl))                                                 return -EINVAL;                                 goto fref_clk;                 }                 /* TCXO clock is selected */                 if (!wl128x_is_tcxo_valid(wl))                                 return -EINVAL;                 *selected_clock = wl->tcxo_clock;                 goto config_mcs_pll; fref_clk:                 /* FREF clock is selected */                 printk("FREF clock is selectedd\n");                 if (!wl128x_is_fref_valid(wl))                                 return -EINVAL;                 *selected_clock = wl->ref_clock; config_mcs_pll:                 return wl128x_configure_mcs_pll(wl, *selected_clock); }

 5. .config of the Kernel has "CONFIG_WL12XX_PLATFORM_DATA=y".

 

please review the log which is tested with adopted modification in below.

Hi Brandon,

This looks like an SDIO communication issue.
Can you verify if WLAN_EN is being toggled using a scope?

Regards,
Gigi Joseph.

WLAN_EN is working.

Hi Brandon,

In that case, can you verify the complete power up sequence? It is available here: http://processors.wiki.ti.com/index.php/WL18xx_Platform_Integration_Guide#WLAN_Reset.2FPower_up_sequence

Regards,
Gigi Joseph.

The sequence seems no problem.Is there any other thing to check?

Brandon,

the following:

ifconfig wlan0 up
[   22.053752] wl12xx: state: 0
[   22.079958] -------------------------- wifi on --------------------------------
[   26.342744] ------------[ cut here ]------------
[   26.347660] WARNING: at /MCU/ti/work-space-r5.sp5.01/compat-wireless/drivers/net/wireless/wl12xx/sdio.c:126

Indicate that the WL chip is not booted correctly

I know Gigi already requested to check the WLAN_EN and the boot sequence, but it still look as something in that area

In addition, you posted that you made a change in the FREF configuration, can you please revert that (or explain again what was the change and why)?

Shahar

Shahar,

Boot sequence has no problem, and WLAN_EN is working well, as written before.
It is using module and TCXO inside.

FREF change is done by Gigi, for error handling.

BR.

Thanks Brandon,
Please wait while we check what should be done/tested next

Hi,

Which wilink6 module is being used here? Can you attach a picture?

If I remember correctly the commercial wilink8 module used board_ref_clock of 38.4Mhz XTAL while below I see that you have set it up to 26_XTAL

struct wl12xx_platform_data am335xevm_wlan_data = {
                .irq = OMAP_GPIO_IRQ(AM335XEVM_WLAN_IRQ_GPIO),
                .board_ref_clock = WL12XX_REFCLOCK_26_XTAL, /* 38.4Mhz */
                .board_tcxo_clock = WL12XX_TCXOCLOCK_26, /* 26 MHz */
                .bt_enable_gpio = GPIO_TO_PIN(3, 21),
                .wlan_enable_gpio = GPIO_TO_PIN(0, 22), /* wifi- enable */

BR
