MMC/SD on STM3210E_EVAL With uCLinux

Question asked by paiva.thales on Jan 10, 2012
Hi folks!

I'm working with  STM3210E_EVAL and uCLinux. For one week i have tried to activate the SD Card in this board, but no success =(

I compiled the kernel with MMC support and tried to edit the device.tab file but the devices nodes /dev/mmc or /dev/mmcblk (or something like that) never appears in my romfs. Am I missing any step?

Reference:
.config

CONFIG_MMC=y


# CONFIG_MMC_DEBUG is not set

# CONFIG_MMC_UNSAFE_RESUME is not set


# MMC/SD Card Drivers

CONFIG_MMC_TEST=y


# MMC/SD Host Controller Drivers


CONFIG_MMC_STM3210E_EVAL=y

CONFIG_SDIO_UART=y

device.tab

Thanks in advance!
