3.4.5 Flashing Configuration to TPS26750

The Application Customization Tool is used to directly load a configuration onto the TPS26750. To flash a configuration, perform the following steps:

  1. Open the Application Customization Tool
  2. Connect the USB-C end of either a USB-A to USB-C cable or a USB-C to USB-C cable to the Data Type-C port (J6).
  3. Connect the other end of the cable to a laptop or computer with the Application Customization Tool open.
  4. Make sure jumper J11 is populated on the TPS26750EVM.

Note: For evaluating battery charging applications with the BQ25756EVM, connect the BQ25756EVM to the TPS26750EVM after configuration has been successfully loaded AND both Power Type-C and Data Type-C connections have been removed from ports J8 and J6, respectively. Also, make sure nothing is connected to J4. If a new configuration needs to be loaded to the TPS26750EVM, then all connections to the BQ25756EVM must be removed until the new configuration is loaded and ports J4, J8, and J6 are disconnected.

Open the Application Customization Tool and complete the questionnaire; for details on each question, refer to Section 3.4.3. Once the questionnaire is complete and the TPS26750EVM is connected properly, click on Options → Serial Port Configuration to make sure the correct COM port is selected (Texas Instruments, Inc needs to be listed next to the COM port). For reference, see Figure 3-7.

If the TPS26750EVM is unable to connect to the Application Customization Tool, then go through the following debug recommendations:

  1. Make sure the cable connecting the computer to the TPS26750EVM supports data.
  2. Make sure only one tab (or instance, if using the natively run application) of the Application Customization Tool is running at any given time. Multiple tools running simultaneously can cause communication issues.

Once the questionnaires are completed and the TPS26750EVM is connected to the Application Customization Tool, click on Flash To Device → Flash to device from current configuration.

Note: When the tool is flashing the configuration, DO NOT connect or disconnect any cables on the TPS26750EVM. Connecting or disconnecting any cables can cause errors when flashing.

Flashing to Device from an Existing Binary File

If a binary file has previously been generated, then the binary can be loaded directly to the TPS26750EVM instead of filling out the questionnaire again. Make sure the TPS26750EVM is detected and connected to the Application Customization Tool using the above steps, and instead of choosingFlash to Device from Current Configuration under the Flash to Device heading, select Flash to Device From Binary File. Select the desired .bin file from your directory and click OK.

Note: When flashing to the TPS26750EVM from an existing binary, make sure the binary is a Full Flash Binary and not a Low Region Binary. For further details, see Section 3.4.6.3.
