Hi!

Is there any way to change that SD port into a port with
SDIO-support? (maybe ripping sd out and pasting sdio in) ???

Yeah, I would also like to know this, although I would guess it
is a hardware shortfall.

This would enable us to get much more add-ons for this limited
device.

The main missing thing being Bluetooth ! !

Have a look at the link below - who knows, it might just happen.

The info posted there doesn't help since the XDA has a StrongARM and not an XScale CPU.

If you read it properly: a) the article doesn't exclusively talk about XScale b) the person posting wasn't suggesting it applies to the XDA, just not to give up hope.

I have my doubts, but I'm not writing off the possibility of a solution.

Sorry, but you're wrong. There is no way you could try to enable SDIO in the same way on a StrongARM you could do on an XScale.

This is because the XScale has an integrated SDIO-cabable MMC-controller on-chip and the StrongARM has not.

I have to agree. I'm sorry, Martin Long, but you should read the article properly. It's even stated in its headline: "Got X-Scale? Got SD? You have SDIO!"...): The article DOES talk exclusively about XScale.

The XScale processor has an on-chip MMC controller which can be used to support SDIO cards in 1-bit mode if the processor is wired properly (see the comments in the discussion forum on pocketpcthoughts.com).

The StrongARM processor has no on-chip MMC oder SD controller. So the trick suggested in the article would never work for the StrongARM.

Sorry but that is the reality.

I know this doesn't apply to the XDA, however, as I said, the article doesn't exclusively refer to the XScale. Read the line: "Any OMAP processor device"

I wasn't trying to make a point that this definately applies to XDA, just that there may be a way around at some point, but, as I also said, i doubt it.
