Path of the tool within the repository is tools/UnifiedHost-*/UnifiedHost-*.jar

Version and Support information

  • Refer to tools/UnifiedHost-*/readme.txt for information on versions and known issues if any

  • UART Protocol is not supported in Harmony 3 using this tool

Description

  • This host script should be used to communicate with the USB Device HID Bootloader running on the device

  • It implements the Unified bootloader protocol required to communicate from host PC

  • It sends the Normalized Hex File of the application to be bootloaded

Configuring and Using the Unified Host tool

  • Configure the Host PC for setting up IP Address to communicate with the device

    • Go to Control Panel/Network and Internet/Network Connections

    • Open Ethernet properties

udp_host_pc_ethernet_properties
- Double Click on **Internet Protocol Version 4 (TCP/IPv4)**

udp_host_pc_ipv4_click
>

- Configure the IP Address as shown below
    - **IP address : 192.168.1.12**
    - **Subnet Mask : 255.255.255.0**
udp_host_pc_ip_address

  • Double click on tools/UnifiedHost-*/UnifiedHost-*.jar file to launch the Host application

  • Select the Device architecture and Protocol as shown below

unified_host_device_arch

  • Select UDP Protocol

    • Click on configure button to configure UDP port Number and IP Address

Using Unified Host Tool in debugging mode

  • On Windows:

    • Launch Windows Command prompt in tools/UnifiedHost-*/ directory

    • Run below command to launch Unified Host Application in debugging mode

      java -Djava.util.logging.config.file="logging.properties" -jar UnifiedHost-*.jar

  • On Linux

    • For running Unified Host tool in debug mode on linux make use of MPLAB X's Java JRE

    • Launch Linux Command prompt in tools/UnifiedHost-*/ directory

    • Run below command to launch Unified Host Application in debugging mode

      /opt/microchip/mplabx/<MPLAB X Version>/sys/java/zulu8.40.0.25-ca-fx-jre8.0.222-linux_x64/bin/java -Djava.util.logging.config.file="logging.properties" -jar UnifiedHost-*.jar

  • Once the tool is launched refer to steps mentioned above in Configuring and Using the Unified Host tool to program application hex

  • You can see the logs during programming sequence on the command prompt

  • Once done you can open the tools/UnifiedHost-*/app.log file and check for the programming sequence logs
