Driver access to User LEDs: LE49 and LE51 ??

Attempting to port a driver to this platform for a customer of Digi i.e. I work for a 3rd party.
Can anyone tell me to which physical addresses the two User LEDs respond? Would like to use them to debug our driver. Even better if you could provide snippet of code that controls the LED(s).
(At the moment does not appear that our SDIO card is recognized - have verified that registry entries are correct).

Highly appreciative,

Hello Gerald,

I guess you are in WCE platform. is it ?
You have sample application in Linux & WINCE as well.
Try that it will help in accessing user LEDs.

LEDs are GPIO 73 -> GPIO3_9 & 74 -> GPIO3_10.
In code i guess you can access it as GPIO 73 & GPIO 74.
This must be mentioned in sample code coming with WINCE bsp… I found it in linux ESP.

Thanks Bob for the pointer to the H/W reference manual.

Unfortunately, I don’t have access to the CE7 BSP.
That should help me determine if our miniport gets loaded. Odd that I see ‘Card is Present’ from the serial Console port but no indication that an attempt is ever made to load our driver. Wonder if CE7 imposes more constraints on miniports than CE6?
