Re: [Gumstix-users] Vedex XLP6 and SDHC MMC card support

[shamiali2008 <sha...@gm...>]

I am not sure whether this is a U-boot limitation or the mmc controller on
Verdex board(It is using PXA270 and the spec says the mmc controller
supports only SD spec version 1.0/1.1 only).

Highly appreciated if someone can please clarify this. We are planning to
use gumstix verdex board as a data logger and lack of  SDHC MMC support is a
big bottleneck as of now.

Thanks,
Shameer
