Installation
____________________________
1. Install Windows CE 5.00 Platform Builder (PB) to development PC. Note the
WINCEROOT, i.e. the path where the CE 5.0 is installed (generally C:\WINCE500).
2. Double click the batch file "CopyDriverToWinCERoot.bat" to execute it.
This batch file will prompt the user to enter the WINCEROOT. The batch file
will then copy all files and sub-folders of the driver to the WINCEROOT.
The following directory structure shall be seen:
C:\WINCE500\OXSEMI
|------uarts
| |
| |-----....
| |-----buspcie950
| |-----pddpcie950
| |-----serpcie950
| |-----mddpcie950
| |-----isrpcie950
| |-----INC
| \-----....
|
\------....
3. Start Platform Builder and create a new platform.
4. Click “File->Manage Catalog Features” to start “Manage Catalog Features” dialog
5. Click “Import…” button to start “Import Catalog Features” dialog and import
cec files of “pcie950.cec” in the subdirectory of “\uarts\buspcie950\"
6. Add "pcie950" feature to the platform by right-click on its logo and choose
“Add to Platform”
7. Clicking "Project->Set Project Build Order.." to start a "Workspace Project
Build Order" dialog and, if required, rearrange project build order as shown:
isrpcie950
pddpcie950
serpcie950
mddpcie950
compcie950
buspcie950
...
9. Build (or Rebuild) OS using menu command of "Build OS->BUild and Sysgen"
“Add to Platform” if the OS has not been built yet, or build the PCIe950
driver by command of "Build Project->Built All Projects" (with "Clean before
Build" unchecked)
9. The 1st 9 installed (PCIe950) devices are given conventional names of COM1:
to COM9: and all subsequently installed PCIe950 devices will be named as
CMx1: to CMx9: accordingly, where x is a digit of 1 to 9.
10. Each port can be configured using the built-in application "SUART", which can
be started by the command of "Start->Run...->suart".

Modifications required
______________________________________________________________________________
Crystal Frequency
_________________
As PCIE950 family devices have fixed input clock frequency (62.5MHz), the default
Crystal Frequency has been defined in the "buspcie950.Reg" file and should not be
changed in any circumstances.
Interrupt triggering and flow control levels
____________________________________________
Four level control values can be defined in "pci16950.reg" file (brackets indicate
the correcponding 16950 registers, to where the values will be stored when device
driver being loaded):
"RxIntTrigLevel" ------ Receive Interrupt Triggering Level (RTL)
"TxIntTrigLevel" ------ Transmit Interrupt Triggering Level (TTL)
"FlowCtrlLowLevel" ---- Automatic Flow Control Lower Trigger Level (FCL)
"FlowCtrlHighLevel" --- Automatic Flow Control Higher Trigger Level (FCH)
The level control values defined in "buspcie950.reg" file shall be used as default
values by all UART channels.
The level value are expressed in hexadecimal, NOT DECIMAL. For example, to set
the Receive Interrupt Triggering Level to 95, the following line should exist
under the corresponging key:
"RxIntTrigLevel"=dword:5F

Branding / Configuration File using Oxide:
________________________________________________________________________________
The driver supports branding and customization. The user can generate a branding
(or configuration) file using Oxford Semiconductor's Oxide. Using this file, the
user can specify values for crystal frequency, fifo levels, line driver values
etc.
To support branding files, a few changes need to be done to the reg file:
Add the following two entries to the reg file:
"BrandingFile"="pcie_branding_file.oxbx"
"ReadBrandFile"=dword:1
Where "pcie_branding_file.oxbx" is the name of the branding file. This
branding file must be kept in the following folder:
%WINCEROOT%\OXSEMI\UARTS\BrandingFiles
The subkey "ReadBrandFile" specifies the driver whether to read the
mentioned branding file or not. The value of '1' means the driver will
read the file.
Also, in order to download the branding file on to the target platform, the
.bib file should be modified. Add the following line to the buspcie950.bib file under
the 'FILES' section. Please see the buspcie950.bib for an example.
pcie_branding_file.oxbx $(_WINCEROOT)\OXSEMI\UARTS\BRANDINGFILES\pcie_branding_file.oxbx NK SHU
The branding file is also used by the SUART application to modify its
user interface.
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
