HX3 Blaster Plus Tool
❐
While specifying value for the configuration parameters, make sure that the HX3 board design
can support the values wherever applicable. For e.g., if the HX3 board design uses 'active
low' signal to indicate 'over current' state on downstream port, only 0 can be assigned as the
value for 'Over current polarity' parameter in Blaster Plus.
❐
After the configuration data along with the firmware is written to the EEPROM, the pin strap
feature is disabled. This is because the configuration data stored in the EEPROM overrides all
other settings. To enable the pin strap feature again, download only the custom firmware to
the EEPROM using the HX3 Blaster Plus tool and power cycle the HX3 hardware.
❐
When configuration data is downloaded to multiple HX3 devices by enabling Download to all
connected devices , the same serial number shall be used for all the devices.
4.3.4 Generating 'HX3 I2C Slave Mode file' for CY4603 and CY4613 DVKs
Note that the CY4603 and CY4613 DVKs support I2C slave mode operation which enables
configuration of HX3 from an external I2C master.
1. Specify the required configuration settings on the Blaster Plus GUI
2. Invoke ‘Generate HX3 I2C Slave Mode File…’ menu item from the ‘File’ menu as show in
Figure 4-21 .

C master frequency based on the
frequency to be used by the I2C master device which shall be connected to the HX3 DVK.
Provide the path to the HX3 firmware (HX3 EEPROM FW.bin) in
Firmware file to include field.
The HX3 firmware is available under <Install Directory>\HX3 Blaster Plus\Firmware. Also provide
the path to store the output file in
Generated file path field and click Export .
Note: Since the HX3 hardware is configured for custom firmware mode by default, always make
sure to select Include HX3 firmware file and settings in the Generate HX3 I2C Slave Mode
File dialog box .
