Cypress USB Drivers for EZ-USB Kits
6. The Windows hardware wizard pops up prompting user to locate the relevant driver. Follow the
steps 6 through10 explained in section 5.2.1 and point to the following Cyload driver for the rele-
vant CyLoad drivers directory, <Installed_directory>\<Version>\Drivers\CyLoad
a. Windows2000w2k\x86
b. Windows XP(32-bit): \wxp\x86
c. Windows XP(64-bit): wxp\x64
d. Windows-Vista(32-bit): wlh-vista\x86
e. Windows-Vista(64-bit): wlh-vista\x64
f. Windows-7(32-bit): wlh-win7\x86
g. Windows-7(64-bit): wlh-win7\x64\
7. The following files are copied to C:\Windows during binding process
a. CyLoad.spt copied to C:\Windows\system32\Cyload
b. Cyusb.sys copied to C:\Windows\system32\drivers
8. Open the device manager by clicking Start >Run. Type devmgmt.msc in the Run box. In Win-
dows Vista and Windows 7 machines, type the option directly in the vacant box. Expand the list of
USB controllers and observe the following:
a. During script file firmware download the EZ-USB device enumerates as “Cypress EZ-USB
Example Device Firmware Download (3.4.5.000)” due to VID/PID-0x04B4/0x0084 men-
tioned in CyLoad.inf
b. After completely downloading the firmware the EZ-USB device re-enumerates again with
downloaded firmware VID/PID-0x04B4/0x1004.The EZ-USB device updates itself in the
device manager as “Cypress EZ-USB Example Device (3.4.5.000)”. This string confirms
that auto firmware download using CyLoad.spt was successful.
Note The EEPROM image can also be downloaded using CyControlCenter.
6.3.3 Keil Debug Monitor Download using Script and CyMonfx1_fx2lp Driver Package
The Keil debug monitor is used to debug the firmware examples based on the EZ-USB kit.The Keil
monitor program is embedded in script file (mon.spt). The procedure to generate the script file for a
.hex file was explained in section. Using the sample Keil monitor .hex programs located at
<Installed_directory>\<Version>\Target\Monitor, the relevant script file can be gen-
erated. Alternatively, the current script file mon.spt can be used to debug the firmware example. The
detailed list of steps to debug a sample firmware example dev_io is explained in Debugging Using
Keil Monitor Program on page 97.
6.4 SuiteUSB Driver Packages
Along with the EZ-USB Kit contents, the SuiteUSB package is also provided. After the EZ-USB Kit
installation, the SuiteUSB package contents are automatically installed at C:\Cypress\Cypress
Suite USB 3.4.7. The Cypress generic USB drivers are located in the Driver\bin folder. The
Cypress generic USB drivers (ver 3.4.7) are located in this directory for different Windows OS plat-
forms. These are unsigned drivers. For testing the applications provided with SuiteUSB, the Signed
driver package provided under <Installed_directory>\<Version>\“Driv-
ers”\cyusbfx1_fx2lp can be used. The relevant VID/PID necessary to verify the functionality of
each of these SuiteUSB applications is mentioned in Table 6-1 on page 45.
