Hello, Developers.
My goal is to provide MMC/SD card support on at91rm9200 embedded
system. Hardware connected properly with slot A.
In a board-specific .c file I made:
static struct at91_mmc_data __initdata naviboard_mmc_data = {
.slot_b = 0,
.wire4 = 1,
.det_pin = AT91_PIN_PC0,
};
And in board init function:
at91_add_device_mmc(0, &naviboard_mmc_data);
Part of my .config, related to MMC:
# OTG and related infrastructure
#
# CONFIG_USB_GPIO_VBUS is not set
# CONFIG_NOP_USB_XCEIV is not set
CONFIG_MMC=y
CONFIG_MMC_DEBUG=y
# CONFIG_MMC_UNSAFE_RESUME is not set
#
# MMC/SD/SDIO Card Drivers
#
CONFIG_MMC_BLOCK=y
CONFIG_MMC_BLOCK_BOUNCE=y
# CONFIG_SDIO_UART is not set
# CONFIG_MMC_TEST is not set
#
# MMC/SD/SDIO Host Controller Drivers
#
# CONFIG_MMC_SDHCI is not set
CONFIG_MMC_AT91=y
# CONFIG_MMC_ATMELMCI is not set
# CONFIG_MMC_SPI is not set
# CONFIG_MEMSTICK is not set
And mmc-related logs from dmesg. Not depends on card is inserted, or not.

No reaction on SD inserting, no mmcblk* file in /dev.
Please, how do you explain the problem.
Kernel versions I tried: 2.6.30.9, 2.6.32.59
Thanks.
