3. Connect the Mini-B end of a USB cable to connector J46 of the CCG1 Host Demo board and the other end to a
PC/ laptop. The USB-Serial bridge on the CCG1 Host Demo board will enumerate as
“USB Serial Port (COM#)”
under
“Ports (COM & LPT)” and “USB-Serial (Single Channel) Vendor MFG” under “Universal Serial Bus
controllers
”. The drivers will be installed automatically. The USB-Serial drivers can also be downloaded from the

7. Launch the Command line and run the utility using the following command for upgrading the CYPD2103 part
using a firmware image, e.g.,
‘CYPD2103_Main.cyacd’:
cc_flash.exe ..\Firmware\CYPD2103_Main.cyacd f SOP’ MAIN NO_UFP
Note: The LED corresponding to the chip being upgraded (LED1 for U1; LED2 for U2) will not glow during the
upgrade and will turn ON after the upgrade is complete. If the CY4502 board is configured to two chip EMCA
application with both the chips powered, then both the LEDs will glow when the upgrade is complete.
