The important sections in this .INF file are
■
[SourceDisksFiles]
section contains the necessary source files to download the firmware -
cyusb.sys and CyLoad.spt
■
[DestinationDirs]
refer to Windows system folder where the source files are copied-cyusb.sys
copied to
C:\Windows\system32\Drivers and CyLoad.spt to C:\Win-
dows\system32\CyLoad
. For a Windows PC with multiple OS on different partitions the rele-
vant partition for active OS is used to copy the files.
■
The INF file is supported on different Windows OS platforms - 2000, XP, Vista and 7 using stan-
dard OS identifiers NT, NTx86 and NTamd64.
■
‘CopyFiles=CyLoadFW.Files’ refers to another section CyLoadFW.files, which is in turn are
defined as:
❐
[CyLoadFW.Files]
❐
CyLoad.spt
The script file is the actual file defined by this section to be copied into the destination directory
defined in the [DestinationDirs] section.
■
The Cypress generic USB driver (ver 3.4.5) is also copied in a similar manner to Windows OS
System folders defined under [DestinationDirs] section.
■
The VID/PID-0x04B4/0x0084, which is part of the .INF file is linked to Cyload.spt The windows
OS automatically triggers the script using the below statement
HKR, DriverEXECSCRIPT,,%CyLoad.EXECSCRIPT
■
The corresponding strings for VID/PID-0x04B4/0x0084 are defined at the bottom of the
CyLoad.INF file.

How to Test CyLoad Driver Package
To verify the script loading features, follow these steps:
1. The EZ-USB FX1 and FX2LP device enumerates by default with Fuse ROM VID/PID 0x04B4/
8613 and 0x04B4/0x6473 respectively. Follow the process explained in
Driver to EZ-USB Development Board on page 45
to bind the cyusbfx1_fx2lp.inf to EZ-USB
device.
2. After completing the binding process for default fuse ROM VID/PID switch SW2 should be used
to select the side marked as
EEPROM
and SW1 to the side marked as
SMALL
EEPROM
3. Open CyConsole from
Windows
start->All programs->Cypress->Cypress Suite USB 3.4.7
.
Select
Options->EZ-USB interface
from the menu. The EZ-USB interface windows pops up.
Click on
S EEPROM
button and browse to Cyload.iic located at
<Installed_directory>\<version>\CyLoad
.
4. The CyLoad.iic contains VID/PID-0x04B4/0x0084 matching the VID/PID mentioned in the
CyLoad.inf file
5. Press RESET button after programming the
CyLoad.iic
file. The EZ-USB development board
enumerates with the new VID/PID-0x04B4/0x0084
