Problems booting a DM3730 using an eMMC

Other Parts Discussed in Thread: DM3730

 

I have a customer with a hardware platform loosely based on Beagle XM but massively cutdown, it has a Toshiba eMMC device (2GB) on MMC1, and this is intended to act as the boot device.

They are doing a sector wise copy from an micro SD card to the eMMC, the SD card image is built using the DVSDK 4.02.00.06 and is tested on a Beagle XM and the same hardware with a SD card socket hardwired in place of the eMMC device, in both cases a successfully boot is achieved up to the linux prompt.

When they boot from the eMMC xload and uboot do the right thing and the kernel starts, when it gets to mount the file system from the second partition the device recognized as an MMC and the size is reported correctly. However  it hangs at this point and never recovers.

 They are currently adding printks to all the affected drivers but the method we have to use to clone the image onto the eMMC is very slow, so any help offered gratefully received.

 Has anyone else successfully used an eMMC to boot a DM3730?
