SDIO limitations

Kuzmin Alexey

Hello,

We are using WINCE 6.0 with modified Adeneo BSP (version from BSP_WINCE_ARM_A8_01_02_00_Source.exe)." for our new device.
The SDHC driver that included into this BSP operate OK with MMC memory and SD memory card but does't work with SDIO device.
As I know, the SDHC driver was updated by Adeneo in latest release. So I have question:

Have current driver from Adeneo any limitations for SDIO operation (like buffer size in bytes, multibyte read/write operation, data pointers, etc.) ?
What is conditions when we can run (into) with this limitations?

Thanks for answers!

What SDIO device did you try to use on the SD port? Depending on the type of SDIO device you plug, you may need a specific class driver to use on top of SDIO.

Hello,

We are using Wi2Wi Bluetooth/Wifi module W2CBW003. Already added Clent Driver entry following:

[HKEY_LOCAL_MACHINE\Drivers\SDCARD\ClientDrivers\Custom\MANF-02DF-CARDID-9103-FUNC-1]
"Prefix"="NDL"
"Dll"="SDIO8686.dll"
"Instance0"="SDIO8686:SDIO86861"

[HKEY_LOCAL_MACHINE\Comm\ <skipped>

It is hard to tell whether your chip not working comes from a SDIO driver limitation as lots of parts are involved here. Can you provide error log of your problem? That would help narrow down to the faulty layer.

Excuse me, I think, I can't provide it in public view now.

But at first message I asked about host driver only, not about client.

It was unexpected surprise for me when I found error into IsMultipleBlockReadSupported(), in simplest place.

Now SHDC driver havent any limitations and my SDIO bgan works fine.

Thank you, Adeneo, for this funny and costly jokes. )))))))
