Composite Function on OMAP3530 (RNDIS + Serial)

Other Parts Discussed in Thread: OMAP3530

Hi,

I am trying to use USB Composite funtion on OMAP3530 EVM Rev.G(Mistral's) Board.

I have enabled SYSGEN_USBFN_COMPOSITE. The following are the registry entries that I has used

 

[HKEY_LOCAL_MACHINE\Drivers\USB\FunctionDrivers]

"DefaultClientDriver"=-

 

; erase previous default

[HKEY_LOCAL_MACHINE\Drivers\USB\FunctionDrivers]

"DefaultClientDriver"="CompositeFN"

[HKEY_LOCAL_MACHINE\Drivers\USB\FunctionDrivers\CompositeFN]

"ClientDriverList"=multi_sz:"RNDIS","Serial_Class"

Looks the device enumerates properly. The WinXP System is not able to load the drivers for it.

When I use the RNDIS or Serial with out composite PC is able to load the drivers.

Has any one tried the same on OMAP3530?

Please let me know if I have to do any additional steps.

Regards,

GSR

    From my past experience, I have not been able to make RNDIS + serial/mass storage work in composite mode. I was successful in getting serial and mass storage enumerated at the same time on my PC using Composite function (dont have the registry settings with me now but a simple google would help) but never RNDIS. I am not sure if it was something missing in my registry setting or it was an invalid option. I would recommend posting this on MSDN forum as this is more of WinCE core feature.
