TPS65983 test system set up

Other Parts Discussed in Thread: TPS65982, HD3SS460

Hello team,

    Due to customer’s need, I start to deal with TPS65983EVM recently and I have a few questions about the test system. According to the user guide, I assume the hardware system is constructed as below. Am I right? And I’m not sure about the difference of Aardvark and Tiva C Launchpad. Aardvark acts as a tool to download config files into lauchpad? If so, why not use the microB-to-A cable directly? And PC linked to Tiva for just debugging? Like pause and seeing results?

And I’m also not sure about the software usage like TPS6589x config tool, CCS etc. Would you please explain them for us with more detail?

    Hi Susan,

    You mention "According to the user guide, I assume the hardware system is constructed as below." did you include an image in your post? If you did it is not showing up.

    Additionally, is your customer designing a Thunderbolt 3 device? The TPS65983 is designed solely for that end application. If your customer is designing any other kind of USB Type-C and Power Delivery end equipment I would recommend either the TPS65982 or TPS65986 as these ICs are more flexible and their tools and documentation are readily available on TI.com.

    Karl,

        Sorry there was something wrong with the display.My customer don't design thunderbolt 3 and the problem about test system has been solved. But I still have a few questions. First, the firmware has already been loaded into the EVM and I don't have to load the firmware through the untilitiy and application tools, right? Second, about the billboard function, the relevant software is included in the firmware, right? Do we have access to this information? Third, about fast role swap, do we modify part of the hardware to implement this? and when do we have to use this function? Thanks a lot !

    Karl,
    Also I notice the EVM doesn't include SS multiplexer like HD3SS460, so how can it switch to alternate mode? Does the switch bank S1 in the evm include this kind of chips?

    Hi Susan,

    I can answer some of the questions you have regarding the GUIs and TPS65983.

    When you are referring to aardvark, I am assuming you are referring to the FTDI board, also called the USB2MANY board. When we usually talk about the aardvark, it usually refers to the connector rather than the board. The aardvark connector can be used to program/flash our device through the USB2MANY board. You can also use the micro usb-to-A and directly connect the USB2MANY to your PC. The board is very versatile and allows for multiple ways to program/flash/connect to your PC.

    You are correct with the TIVA, we use it more for debugging issues since it allows us to read registers/step-through programs easier.

    Regarding the 83, the 83 does come with EVM firmware that has a few configurations on it. However, if you want to program your own configurations, we have a separate GUI called the "TPS65983 Application Customizer". Keep in mind it only supports Intel reference designs as of now, we will update it soon. After using that GUI, you can program the 83 as normal using the "TPS6598x Utilities GUI".

    Regards,
    Arthur

    Arthur,
    You mean I should use "TPS65983 Application Customizer" to configure something like DFP/DRP/UFP and power path, and then use "TPS6598x Utilities GUI" to load the firmware ? And also how do we manage to read registers/step-through programs by TIVA?

    Yes, that is correct. 

    You do not require a TIVA to read registers, the FTDI board and Utilities GUI both allow for the user to read registers and update them directly.
