Other Parts Discussed in Thread: AM3352

Hello

I have a custom board based on AM3352 with 2 SD cards, but only one mmc0 is recognized and working well in linux :

[    2.499206] mmc0: host does not support reading read-only switch. assuming wr
ite-enable.
[    2.509399] mmc0: new high speed SD card at address 0260
[    2.515594] mmcblk0: mmc0:0260 SD    977 MiB
[    2.523162] mmcblk0: p1 p2 < >

in the board-am335Xevm.c file i added the mmc1_init call with the correct pinmux.

Where must we declare the number of SD-card for linux

regards

thanks

Hi,

For reference look how this is done in the evm_dev_cfg structure for the General Purpose EVM inside board-am335xevm.c:

{mmc1_init, DEV_ON_DGHTR_BRD, PROFILE_2},

Please note that this only works in CPLD profile 2 of the EVM, because otherwise these pins are used for the NAND flash.

Best regards,
Miroslav

And make sure you have that line before the mmc0_init.

Hello

thanks for your reply; i have made the following modifications for my second SD card :

1° call mmc1_init :

{mmc1_init, DEV_ON_BASEBOARD, PROFILE_ALL}, /* added */
{mmc0_init, DEV_ON_BASEBOARD, PROFILE_ALL},

2° update mmc1 init according to my GPIOs for CD and WP :

static void mmc1_init(int evm_id, int profile)
{
   setup_pin_mux(mmc1_common_pin_mux);

   am335x_mmc[1].mmc = 2;
   am335x_mmc[1].caps = MMC_CAP_4_BIT_DATA;

   am335x_mmc[1].gpio_cd = GPIO_TO_PIN(0, 14); //GPIO0_14

   am335x_mmc[1].gpio_wp = GPIO_TO_PIN(3, 18); //GPIO3_18

   am335x_mmc[1].ocr_mask = MMC_VDD_32_33 | MMC_VDD_33_34; /* 3V3 */

   /* mmc will be initialized when mmc0_init is called */
   return;
}

3° update mmc1_common_pin_mux according to my GPIOs

static struct pinmux_config mmc1_common_pin_mux[] = {
    {"gpmc_ad11.mmc1_dat3",   OMAP_MUX_MODE1 | AM33XX_PIN_INPUT_PULLUP},
   {"gpmc_ad10.mmc1_dat2",   OMAP_MUX_MODE1 | AM33XX_PIN_INPUT_PULLUP},
   {"gpmc_ad9.mmc1_dat1",   OMAP_MUX_MODE1 | AM33XX_PIN_INPUT_PULLUP},
   {"gpmc_ad8.mmc1_dat0",   OMAP_MUX_MODE1 | AM33XX_PIN_INPUT_PULLUP},
   {"mcasp0_aclkr.gpio3_18", OMAP_MUX_MODE7 | AM33XX_PIN_INPUT_PULLUP}, //WP
   {"uart1_rxd.gpio0_14", OMAP_MUX_MODE7 | AM33XX_PIN_INPUT_PULLUP}, //CD
    {"gpmc_csn1.mmc1_clk",   OMAP_MUX_MODE2 | AM33XX_PIN_INPUT_PULLUP},
   {"gpmc_csn2.mmc1_cmd",   OMAP_MUX_MODE2 | AM33XX_PIN_INPUT_PULLUP},
   {NULL, 0},

4°keep the following struture

static struct omap2_hsmmc_info am335x_mmc[] __initdata = {
   {
       .mmc            = 1,
       .caps           = MMC_CAP_4_BIT_DATA,
        .gpio_cd        = GPIO_TO_PIN(0, 6),
        .gpio_wp        = GPIO_TO_PIN(3, 18),
       .ocr_mask       = MMC_VDD_32_33 | MMC_VDD_33_34, /* 3V3 */
   },
   {
       .mmc            = 0,   /* will be set at runtime */
   },
   {
       .mmc            = 0,   /* will be set at runtime */
   },
   {}      /* Terminator */
};

The only line concerning mmc1 is the following : mmc1: mmc_rescan_try_freq: trying to init card at 400000 Hz

-> I put the MMC_DEBUG_TRACE and get trace about wl12xx_sdio : can it be the problem ; how can i suppress that ?

-> Have you any clue why my SD2 is not recognize ?

-> should am335x_mmc structure be modified ?

Thanks a lot

Hello

is there a way to suppress "Performing wifi calibration... "
and disable the wl12xx_sdio loading ? (maybe it is making trouble on my mmc1 ?)

thanks

The calibration is done by the /etc/init.d/calibrate.sh script. You can remove this script from the Runtime Control with the following command:

update-rc.d -f <script_name> remove

Hello

thanks for your reply, that's correct, i don't have any more trace about wl12xx, but my mmc1 is still not working...

Have you any idea ?

i have made the following modifications to have a second SD card reader :

1° call mmc1_init :

{mmc1_init, DEV_ON_BASEBOARD, PROFILE_ALL}, /* added */
{mmc0_init, DEV_ON_BASEBOARD, PROFILE_ALL},

2° update mmc1 init according to my GPIOs for CD and WP :

3° update mmc1_common_pin_mux according to my GPIOs

4°keep the following struture

Hi,trichet christophe :

I have got the same problem like you.The kernel log only has the info "mmc1: mmc_rescan_try_freq: trying to init card at 400000 Hz".

I use the mmc_data as MODE_2,it doesn't work.How did you resolve the problem?

Thank U very much!
