X51V SD Specs

Greetings Folks

In another thread of mine it came up about whether the Axim V51(V) supports the new SDHC (2.0) spec. Does anyone know for sure one way or the other ?

Not yet. But since the main difference between SDHC and SD cards appears to be a software issue it is theoretically possible that Windows Mobile 6 or even and independent software dev. could include a driver for the new storage card format.

I'm crossing my fingers that they will eventually put out a patch that will upgrade it, much like Casio did for my digicam upgrade to SDHC.

If you all read the link I put up in the other thread under "Fake Sandisk 4GB card", as per this link off the SD Association's website, on Page 17 they mention that there are some differences between 'normal' SD cards and SDHC ones - and that they've also provided in the specification a way to have SD cards which have both SDHC and SD capability... but that's only accessible through a physical switch. This suggests that there's also some changes to the way the cards are accessed by the units in question, which goes beyond software or file allocation table differences - otherwise PCs wouldn't require SDHC-capable readers, like the one that SanDisk is bundling with every 4GB SDHC card they're selling.

It's probably like the difference between CDs and DVDs, all over again...

That doesn't mean it's a software change - the slot itself is probably already SD 2.0 capable as those cameras referenced were all manufactured in the past two years... which is when the standard was finalized, as per the specification sheet I listed; the firmware change is likely there just to allow the camera to use all of what the hardware's capable of doing, much like AKU 3 for Windows Mobile 5 enables WPA2 for WPA2-capable hardware... but isn't likely to make an iPaq h3600 WPA-capable, since it doesn't even have the WiFi hardware in place. This rather like assuming that because a DVD drive was given a firmware change that allows it to read a few more DVD formats, that a CD drive is also capable of reading those DVD formats with a firmware update.

As I noted in that reference straight from the SD Association which defines the SD Standard there are apparently more changes than just software to the SDHC (SD 2.0) standard. I'm starting to be reminded of the people who assume that SanDisk is releasing SD 1.1 4GB cards, just because someone said that SanDisk was doing so, ignoring their press releases and the website.

Edit: Changed the [/url] tag to [/b] to actually bold the text I wanted bolded. SHows me for posting this at like 3AM.

Guess Dell would have to do a ROM update for us if that is even possible. I will not hold my breath though.

Then why is there not a similar probability that the X51 series' slot is not already SDHC capable yet just needs a firmware refresh as it's of similar vintage?

Anyways, thanks for the links to the SDHC specs.

I think there are some differences in our posts. You are posting the SDHC specs. and I have no intention to argue against those factual specs. My posts are based clearly on wishful thinking that I hope will occur and at the same time citing an example of where the upgrade was possible.

It could be very likely that some manufacturers (Casio) had the foresite to implement the SDHC hardware into the slots during the previous two years and only needed a firmware upgrade to unlock the goods, yet other manufacturers choose not to. I still hope Dell is in the former group. :)

Probably because PDAs are NOT cameras - and they aren't usually the designers aren't the most forward-thinking of folk when it comes to accessories.. or things they put onto them for that matter. Plus, in order to save costs, a lot of other unnecessary features have been trimmed. Remember back when iPaqs came with CIR, rather than the cheaper IR transmitters which have since become the de-facto standard across the board? Or how Windows Mobile 5 devices come with 64MB of RAM for the most part, despite the fact that the OS takes up about half of it under normal operation?

As I said in my previous post, Casio was thinking ahead and put the hardware in place for it, requiring just a firmware unlock, because cameras NEED the extra memory capacity. Nobody in 2004 seems to have thought the PDA to be useful for more than the odd MP3 or web browsing, to judge by how the feature sets of PocketPCs circa 2004 were less than friendly to multimedia - it's rather like they expected everyone to get Personal Media Players as well as their Dells and their iPaqs. Given Dell's mania about cutting costs in order to keep things reasonably priced (which explains the VGA screens which aren't as vivid as that of the hx4700's or LOOXs of the world), I have my doubts that they asked HTC to give it anything but basic SD/SDIO functionality.

All great points Haesslich.

As rlarson_mn says, I shouldn't hold my breath.

You could hold it, but you'll probably pass out before any new ROM updates show up...

This is really a shame.... SDHC 8GB cards are under 80$ now.

We'll have to wait for someone to develop a driver for it. Here's something I noticed in the registry of my Axim x51v

HKEY_LOCAL_MACHINE/Drivers/BuiltIn/SDHC
Default (value not set)
CardDetectIRQ 0x20(32)
CardDetectISTPriority 0x65(101)
ClockAlwaysOn 0x0(0)
ClockOnIfInterruptsEnabled 0x1(1)

going down two more lines in the same registry key,

DLL pxa27x_sdhc.dll

Anyone smart enought to figure why this is in the registry if it can't even recognize a SDHC card?

SDHC according to Microsoft = SDIO standard Host Controller
SDHC according to SanDisk = SD High Capacity

It's got nothing to do with SDHC functionality.

Thanks for the clarification. Hope a driver is develop soon.
