Thanks Marcel for your kind explanations.<br>I am sure hardware specs at N800/N810 is an issue, so what <br>I mean is SPIO gps card ( gps + sd memory card) made as gps logger<br>and have software solution at N800/N810 reading nmea sentences saved in memory cells as a gps data file.<br>So SD memory card should act as gps sentences buffer.<br>I am aware I should ask that question to vendors of SDIO cards too.<br>Such solution would be welcome by owners of old PDAs with only one memory card slot (CF or SD) and not bt, wifi or internal gps enabled.<br><br>Market is open for millions of such modified SPIO gps cards bundled with software drivers for no-SDIO controller phone/ smartphones/ PDAs, Palms<br>manufactured in the past.<br><br>http://www.arasan.com/products/prod_overview/AC2200-Flyer-1-0.pdf<br> <br>It would be nice to have that solution incorporated into N800s one day.<br>I can donate one used N800 for tests.<br><br>Darius<br><br><b><i>Marcel Holtmann

While it<br>might work, it is a really bad example of doing a SDIO stack. However<br>starting with 2.6.24-rc1 the Linux kernel has its own SDIO stack which<br>is working perfectly fine. It
also comes with host and bus controllers<br>and drivers for GPS, Bluetooth and Marvell WLAN drivers. A driver for<br>the AR6k cards from Atheros are work in progress.<br><br>However the real problem is to get a working host driver. While on most<br>laptop based system the host will follow the SDHCI standard, in the<br>embedded world it is a special host controller. And while most<br>controllers are supported, this doesn't automatically mean the will work<br>with SDIO. In theory they should, but the reality with this embedded<br>host controllers is different.<br><br>So if the MMC/SD controller inside the N800 supports SDIO (this is not a<br>must and didn't look at the hardware specs for it), then you might get<br>lucky and it works or you have to port the host controller to support<br>SDIO. After that you actually have to check if your specific GPS card<br>follows the specification or if it needs a vendor
