Integrating TiWi-R2 (WL1271) with AM3354 using 1.8V SDIO/MMC?

Hi Andrew,

Can you try with the official SDK 5.07 filesystem and see if the same problem still exist?
Also, can you post the commands you entered and messages you saw as well?
It looks like your WL1271 card is either defective, not inserted correctly, or something else is wrong in the filesystem.

Hi Victor,

It took me a while to get everything going, but here is what I have found:

I am using 'ti-sdk-am335x-evm-05.07.00.00' and the associated 'linux-3.2.0-psp04.06.00.10' kernel - modifying the 'board-am335xevm.c' (3240.board-am335xevm.c) board file for my purposes.

I have connected the TiWi-R2 to MMC1 according to the following mux configuration:

static struct pinmux_config mmc1_jaguarshark_wifi_pin_mux[] = {
{"gpmc_ad8.mmc1_dat0", OMAP_MUX_MODE2 | AM33XX_PIN_INPUT_PULLUP},
{"gpmc_ad9.mmc1_dat1", OMAP_MUX_MODE2 | AM33XX_PIN_INPUT_PULLUP},
{"gpmc_ad10.mmc1_dat2", OMAP_MUX_MODE2 | AM33XX_PIN_INPUT_PULLUP},
{"gpmc_ad11.mmc1_dat3", OMAP_MUX_MODE2 | AM33XX_PIN_INPUT_PULLUP},
{"gpmc_csn2.mmc1_cmd", OMAP_MUX_MODE2 | AM33XX_PIN_INPUT_PULLUP},
{"gpmc_csn1.mmc1_clk", OMAP_MUX_MODE2 | AM33XX_PIN_INPUT_PULLUP},
{NULL, 0},
};

The additional GPIO lines for WLAN_ENABLE/IRQ, as well as the 'wl12xx_platform_data' structure are as follows:

#define JAGUARSHARK_WLAN_PMENA_GPIO GPIO_TO_PIN(1, 12)
#define JAGUARSHARK_WLAN_IRQ_GPIO GPIO_TO_PIN(1, 13)

struct wl12xx_platform_data am335xevm_wlan_data = {
.irq = OMAP_GPIO_IRQ(JAGUARSHARK_WLAN_IRQ_GPIO),
.board_ref_clock = WL12XX_REFCLOCK_38_XTAL, /* 38.4Mhz */
.bt_enable_gpio = GPIO_TO_PIN(1, 28),
.wlan_enable_gpio = GPIO_TO_PIN(1, 12),
};

static struct pinmux_config wl12xx_jaguarshark_pin_mux[] = {
{"gpmc_ad12.gpio1_12", OMAP_MUX_MODE7 | AM33XX_PIN_OUTPUT}, // WLAN ENABLE
{"gpmc_ad13.gpio1_13", OMAP_MUX_MODE7 | AM33XX_PIN_INPUT}, // WLAN IRQ
{"gpmc_ben1.gpio1_28", OMAP_MUX_MODE7 | AM33XX_PIN_OUTPUT_PULLUP}, // BT ENABLE
{NULL, 0},
};

The MMC for wl12xx is initialised as follows:

static void mmc1_jaguarshark_wl12xx_init(int evm_id, int profile)
{
setup_pin_mux(mmc1_jaguarshark_wifi_pin_mux);
am335x_mmc[1].mmc = 2;
am335x_mmc[1].name = "wl1271";
am335x_mmc[1].caps = MMC_CAP_4_BIT_DATA | MMC_CAP_POWER_OFF_CARD;
am335x_mmc[1].pm_caps = MMC_PM_KEEP_POWER;
am335x_mmc[1].gpio_cd = -EINVAL;
am335x_mmc[1].gpio_wp = -EINVAL;
am335x_mmc[1].ocr_mask = MMC_VDD_165_195; // 1.8V
am335x_mmc[1].nonremovable = true;
}

The board config structure is as follows:

static struct evm_dev_cfg jaguarshark_dev_cfg[] = {
{am335x_rtc_init, DEV_ON_BASEBOARD, PROFILE_NONE},
{clkout2_enable, DEV_ON_BASEBOARD, PROFILE_NONE},
{tps65217_init, DEV_ON_BASEBOARD, PROFILE_NONE},
{rgmii1_init, DEV_ON_BASEBOARD, PROFILE_ALL},
{usb0_init, DEV_ON_BASEBOARD, PROFILE_NONE},
{usb1_init, DEV_ON_BASEBOARD, PROFILE_NONE},
{mmc1_jaguarshark_wl12xx_init, DEV_ON_BASEBOARD, PROFILE_ALL},
{mmc0_init, DEV_ON_BASEBOARD, PROFILE_NONE},
{wl12xx_init, DEV_ON_BASEBOARD, PROFILE_ALL},
{NULL, 0, 0},
};

Hardware-wise, I have 10k pull-up resistors on SDIO_D0...3 and SDIO_CMD. VDDSHV1,2,3 are supplied with 1.8V.

So with all this in place, and some other necessary changes made to bring up my board with the TI SDK I still cannot get the wlan SDIO to work. I have double checked the hardware and pin-mux settings, so I am sure I am using the correct pins as configured, so I'm still wondering if there is something fundamentally wrong with using 1.8V for SDIO - are you sure that support has been added for 1.8V SDIO since release 04.06.00.07?

My dmesg output is as follows: It appears I am getting sdio read failure (-84 return code) - do you have any other suggestions for things to try - or changes that I could make to my boads file?

Hi Andrew

I am using Beagle Bone A6 with Tiwi-5E WiF module and getting the same error message as you have observed. Did you successfully solve the issue  ?

I have posted a query in http://e2e.ti.com/support/low_power_rf/f/307/t/291593.aspx

Can you help me out to solve this issues. Appreciate your help.

Sunil 

1.8v support is just fine.. otherwise card detection would not have worked.

The mux/pad seem to be fine..did you scope the mmc clk line and see if the clk are not cut off..

there seems to response from the chip and irq line is toggled and sdio read is getting stuck?

enable MMC_DEBUG from the kernel config..

Thanks

Vijay

Hi Vijay

I have observed the slow clock which is 32K looks fine and voltage is 1.8V. Do i need to enable any configuration for SDIO ?

Hi Vijay

Find the log after enabling the mmc_debug
