SDRW - SDIO

[Anonymous]

Just read some good news about SDIO. According to www.cewindows.net there is a rom upgrade for Ipaqs that make them SDIO compatible. http://www.cewindows.net/faqs/sdioupdates.htm Hopefully it is just a matter of time before a patch for the XDA is released as well. I also read that in windows ce.net there will be support for SDIO, so let's just hope it is possible to upgrade the XDA to .net.

Just read some good news about SDIO [...]

Before everyone gets their hopes up: the SD port on the XDA appears hooked up to a custom HTC-built ASIC. Not saying upgrade is impossible, but if there is a future upgrade, it is likely to be very different from the iPaq upgrade.

Since HTC makes the iPAQ, is it not the same ASIC?

From what I read, it seems that the upgrade has little to do with the hardware providing the SD port as long as it supports the same basic api. Also, as HTC is making the Ipaq, it seems probable that the SD-chipset is not all that different between the two.

As far as I have read it the current change to allow SDIO is related to two things. First it seems mandatory to have a IRQ line connected to a GPIO line. If this hardware connection is not there someone suggested polling, but I doubt that is workable.

The second thing I've noticed so far all concrete examples were for the Xscale. There were also some indications this was a nessecary prerequisite.

So I'd say the chances for XDA are very slim.
