Hi Jagannadha,
Hi,
I need some help on mmc driver development on u-boot.
Few questions:
- is mmc framework in u-boot supports all type of card interfaces
like SD, MMC, and eMMC
Yes there is a generic framework for MMC. -> ./drivers/mmc/ {mmc.c}
- If I write a driver do I need to develop
the common driver for all or a separate drivers for individual cards.
This is a generic framework. Normally you only need to write MMC controller specific code to use it.
- Is there any drivers in current u-boot drivers/mmc have individual
card interfaces support (SD & MMC & eMMC)
AS fair as I know there aren't any "special" drivers for any particular vendor.
- is there any drivers in
current u-boot driver/mmc for common card intefaces (SD | MMC | eMMC)
Yes, you can refer to mmc.c One good example is the sdhci.c code which serves for SD cards and eMMC (at least for Samsung).
Request for help.
Thanks, Jagan.
