Tool/software:

Hi,

It is the first time I have used TPS25751+BQ25798.
I want to know correct test procedure.
If there is wrong, please let me know.

1. Flashing Configuration onto TPS25751EVM, refer to figure1
    1.1. Connect J4 Type-C connector with a cable to computer.
    1.2. Connect J2 Type-C connector to supply VSYS (15-20V), in order to get PP5V & P3V3.
    1.3. Open the Application Customization Tool and setting configurations, then export xxxx.bin.

2. My own TPS25751+BQ25798 PCB board., refer to figure2
    2.1. Add DC source to supply VSYS (15V-20V). In order to get PP5V & P3V3.
    2.2. Write to EEPROM (xxxx.bin) by Aardvark I2C/SPI Host Adapter.
    2.3. Remove Aardvark & DC source.
    2.4. After writing the EEPROM, connect J3 Type-C connector to start the board.

thank you.

    Hi Mulin,

    See my comment in bold

    1. Flashing Configuration onto TPS25751EVM, refer to figure1
        1.1. Connect J4 Type-C connector with a cable to computer.
        1.2. Connect J2 Type-C connector to supply VSYS (15-20V), in order to get PP5V & P3V3.
        1.3. Open the Application Customization Tool and setting configurations, then export xxxx.bin.

    • 1.4 In the bottom left, you should see "Hardware Connected" which indicates the EVM has connected over J2
    • 1.5 Once configuration is ready use "Flash To Device, from current config or from binary" to flash to EVM

    2. My own TPS25751+BQ25798 PCB board., refer to figure2

        2.0 Generate Full Flash binary xxxx.bin from GUI
        2.1. Add DC source to supply VSYS (15V-20V). In order to get PP5V & P3V3.
        2.2. Write to EEPROM (xxxx.bin) by Aardvark I2C/SPI Host Adapter.
        2.3. Remove Aardvark & DC source. Power cycle PD controller by removing P3V3 and remove anything attached to J3.
        2.4. After writing the EEPROM, connect J3 Type-C connector to start the board.

       

    Your process mostly looks good, made some notes to clarify certain steps.

    Thanks and Regards,
    Chris
