We have been working on supporting on-chip Ethernet controller (similar to
TOSHIBAS tc35815 Ethernet controller) of TX4938 on WindowsCE .NET Operating
System.

TX4938 supports 2 Ethernet channels which are connected to the internal PCI
controller. To get access to the registers of the on-chip Ethernet
controller, the internal PCI controller was initialized at the HAL layer and
the MBASE registers of the on-chip Ethernet controller were hard coded.

And in the driver code of on-chip Ethernet controller, we are reading the
assigned address (physical) from the registry entry using
NdisOpenConfiguration & NdisReadConfiguration functions in
MiniportInitialize function. Referring to NDIS API's, to map the registers
of the on-chip Ethernet controller, we tried to use
NdisMAllocateMapRegisters function but ended up with errors. So we mapped
the registers using MmMapIoSpace function call and were successful in
accessing the registers. Later we implemented transmit and receive function
with required buffer management and interrupt functions. All the above
mentioned were done without KITL support. But when we added KITL support and
tested the Ethernet driver, it generates exception in ISR function call at
the first register access statements. Below is the displayed message when
exception occurs:

Could someone please give some inputs regarding the exception generated, and
how it could be eliminated?

Thank you.
