Hello All,

 

I have successfully build and booted linux kernel on imx233 via NAND flash.

Now I wanted to mount SD card on it. However I am not able to find any mmc files in /dev folder of the booted kernel.

I have already enabled the following MMC related configuration symbols while building kernel:

 

#

# OTG and related infrastructure

#

CONFIG_USB_OTG_UTILS=y

# CONFIG_USB_GPIO_VBUS is not set

# CONFIG_NOP_USB_XCEIV is not set

# CONFIG_MXC_OTG is not set

CONFIG_MMC=y

CONFIG_MMC_DEBUG=y

CONFIG_MMC_UNSAFE_RESUME=y

 

#

# MMC/SD/SDIO Card Drivers

#

CONFIG_MMC_BLOCK=y

CONFIG_MMC_BLOCK_BOUNCE=y

CONFIG_SDIO_UART=y

CONFIG_MMC_TEST=y

 

#

# MMC/SD/SDIO Host Controller Drivers

#

CONFIG_MMC_SDHCI=y

CONFIG_MMC_SDHCI_PLTFM=y

CONFIG_MMC_SPI=y

CONFIG_MMC_IMX_ESDHCI_PIO_MODE=y

CONFIG_MMC_MXS=y

# CONFIG_MEMSTICK is not set

# CONFIG_ACCESSIBILITY is not set

# CONFIG_NEW_LEDS is not set

CONFIG_RTC_LIB=y

CONFIG_RTC_CLASS=y

CONFIG_RTC_HCTOSYS=y

CONFIG_RTC_HCTOSYS_DEVICE="rtc0"

# CONFIG_RTC_DEBUG is not set

 

Please help me in this regard.

I have attached the completed configuration also.

 

Thanks in advance

 

Regards,

Venkatesh

Hi Venkatesh

please refer to sect.22.5 Menu Configuration Options

attached document and L2.6.31_10.05.00_SDK_SOURCE : Linux 2.6.31

Source Code Files.

Note gpmi (nand) are used also for ssp2 interface, iMX23 EVK uses ssp1.

Best regards
