Hi, May be this is already discussed here, but different threads say different things, so please clarify. I am using a gumstix verdex XLP6 board and is able to mount/read/write to a 1GB microSD card. But the 2GB microSDHC card is not detected by gumstix at all. I had a look at the linux mmc core drivers and they seems to have support for SDHC. The PXA27x spec says, mmc controller only suppports SD specicfication 1.0/1.1v. But i think SDHC requires rev 2.0 of the spec. Can somebody please clarify whether gumstix verdex supports SDHC or not..

Hi Shameer, I believe that the older version of uboot (1.2.0) on the Verdex line does not support SDHC cards; I can access a microSD in uboot on my Verdex XM4 but not a microSDHC. My SDHC (4GB) card is accessible in Linux though using the default 2.6.21 kernel. -Ash On Thu, Feb 4, 2010 at 1:33 PM, shamiali2008 <sha...@gm...> wrote: > > Hi, > > May be this is already discussed here, but different threads say different > things, so please clarify. > > I am using a gumstix verdex XLP6 board and is able to mount/read/write to a > 1GB microSD card.

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.

Hi Shameer, Hmm - that's interesting. I can confirm that I am able to access a SDHC card on my Verdex XM4 using Linux 2.6.21; this is a 4GB Lexar card. <<<<<<<<<<-----snip---->>>>>>>>>>>>> Thanks for your reply. Just to clarify, when you say accessible through linux, is this on a gumstix verdex board or a PC? I have tried with a Sandisk 2GB microSDHC and both u-boot and linux 2.6.21 on verdex board fails to detect the card. <<<<<<<<<<-----snip---->>>>>>>>>>>>> N.B.

Well if thats the case, it might be a card problem. But interestingly the card works fine on my laptop. Anyway will try with a Lexar one.
