Hi Praveen,
Sorry it took so long to answer, but this has been a holiday and I've been
away.
I'm responding to two questions.
1.
> One thing more there are two notifications for knowing Start-UP viz.
> 1)sysNotifyLateWakeupEvent
> 2)sysNotifyEarlyWakeupEvent

I do not use the early wakeup, or at least do not rely on it, because it is
not reliable. I have found that it is not always sent.
2.

I was attempting to explain the way the 16 bit (UInt16) dock status word is
passed in the sysExternalConnectorAttachEvent notification. The notification
structure includes a (void*) notifyDetailsP. Normally, this is a pointer to
data. In the sysExternalConnectorAttachEvent notification, notifyDetailsP is
not a pointer, but the actual dock status cast to a (void*). Use it like
this:
Err NotifyCallback(SysNotifyParamType * pNotifyParam)
{
UInt16 dockStatus = (UInt16) pNotifyParam->notifyDetailsP;
}
My second point is that the dock status passed in the notification is what
was immediately known at the time of the connection. Other functions such as
charging are initiated after the connection event. If you need to how the
platform responded to the attachment, you must poll the dock status some
time after the attach notification. The dock status API may not be exposed,
so I included a definition.
> UInt16 HwrDockStatus(void) SYS_TRAP(sysTrapHwrDockStatus);
Hope this helps.

Hi Jeffry,
Thanks for the reply.
Can you please explain the details given in the below mail. I could not
follow it.
Thanks and regards,
