I have a verdex pro XL6P based computer with a gumstix-oe system
Everything works fine, but for the SD Card, i m unable to mount a 4GB SD.
I can how ever mount 1GB SD without problem.
If i'm putting the 4GB SD on a external usb device, then the 4GB SD
on the exact same system.
Does anybody knows why ? and if it's patchable ?

I did the same and the card is readable if it's in the card reader
since bootstrap, but it's never possible to write on it or to mount
it. As I wrote I tried with different models and sizes and I always
got the same results. Tomorrow I will try with a mmc card: I hope I
won't have problems.

I think it is possible; maybe you can try with different cards, made
by different brands.

I have a waysmall 400xm-bt, and I have the directory you mentioned
listed under /dev. For me this is a mistery :)
Le domande non sono mai indiscrete. Le risposte lo sono, a volte
The protocol for SD cards with more than 2GB of storage is different than 2GB
and under. They are usually called SDHC (SD high capacity). I think there is
something you need to enable in bitbake to make SD cards with more than 2GB

I use a SanDisk 8GB SHDC memory card. It works fine with the Overo.
The package I bought had this nice little USB adapter, so I use Linux
running on a VMware image and use the USB adapter to program the SHDC
card and insert it into the Overo.
