Problems with Cisco WinCE 3.0 driver v. 2.20 for X86 platfoms

[h.bleier]

The installation of the Cisco WinCE 3.0 driver v. 2.20 for x86 platforms passes correctly. But the driver "cisco.dll" crashes with an "Access Violation" and shows the following messages:

Debugger Listing

-------------------

Exception 00e Thread=87cbae6c Proc=87ee42ce 'device.exe'

AKY=00000009 PC=00ee4032 ESP=0839eca0 EA=00000332

Assembler Listing

--------------------

009D4032 mov word ptr [ecx],ax <= Access Vioaltion in cisco.dll

009D4035 ret

009D4036 mov ecx,dword ptr [esp+4]

009D403A mov eax,dword ptr [esp+8]

009D403E mov dword ptr [ecx],eax

009D4040 ret

The EA-value of the debugger listing depends on the registry key "IoBaseAddress"=dword:00000300. If the value of the registry key "IoBaseAddress" changes also the EA-Value changes. It seems that the driver wants to address the registers of the wireless pcmcia card,

but the registers of the card are mapped in I/O space and not in memory space.

The same problem exists when WinCE 3.0 driver v. 2.00 is installed.

But the driver WinCE 2.10 v. 1.40 works correctly.

Is there a bug in these drivers or is this a configuration problem?

This sounds bug related. Do you have an out of the ordinary setup as far as PCMCIA?

[h.bleier]

To install the wireless driver I used the file "WinCe3.0-PCM-LMC-v2.20.exe" which I got from the CISCO homepage. Before starting the setup program there was no other wireless driver installed. The installation was done as described in file "WinCe-ReleaseNotes-v2.20.pdf". The PCMCIA Controller is PCI1520 form Texas Instruments which works in 82365SL Mode. Our device runs WindowsCe 3.0 with the standard PCMCIA-Driver (pcmcia.dll). There is nothing out of the ordinary setup procedure. By the way older versions of the driver (V1.40 WinCe 2.10) works correctly on this platform.
