How to 8GB nand memory along with 4GB on chip eMMCto GPMC in Beable bone using device tree in kernel

Hi Dhvanil,

BBB and kernel 3.8 are supported by the community at http://beagleboard.org/Community/Forums However, what you want requires switching the 8 data pins between GPMC and MMC1 modes. I don't know whether this would be feasible in a real design.

Thanks you response.

GPMC can handle multiple devices right?

We are only adding another 8GB Nand flash using GPMC. Is this possible with GPMC?

We want only one flash is active at time using GPMC control signal.

If this is possible then can you provide me kernel device tree for this configuration.

Thanks in advanced,

I think you didn't understand me. The eMMC uses the same data pins as GPMC, but they are configured as MMC1 pins. eMMC cannot be accessed via the GPMC interface.

Sorry, I cannot help. This isn't a use case that's ever been considered. For kernel v3.8 I suggest you turn to the community at http://beagleboard.org/Community/Forums
