TPS65987DDK: FTDI device for custom board

Ryuuichi machida
Guru 12655 points
Part Number: TPS65987DDK
Other Parts Discussed in Thread: TPS65987

Tool/software:

I would like you to confirm about below.

* We are trying to implement FT4232HL on our custom board.
For previous TPS65987 EVM, even though I did not perform any write to FT4232HL, I could communicate to PC.
And also, we could confirm communication b/w PC and TPS65987 via FT4232H mini module without any write to FT4232H mini module.

However, I'm concerned if we implement FT4232HL to custom board directly, I think that I need to write something program to FT4232HL.
Then, I have following question.

1. If I implement FT4232HL to custom board directly, should I need to write something program to chip ?
2. If answer of Q1 is yes, where can we get this program ?

Best Regards,

    Hi,

    Additionally, we refered following information and use same circuit/connection around FT4232HL.

    Hi Ryuuichi, 

    Thank you for reaching out!

    I am looking into this and will get back to you with feedback tomorrow.

    Hi Ryuuichi, 

    The flashing feature on the GUI is intended to be used in conjunction with TI EVMs and is enabled by the use of the FTDI or TIVA controllers. However, the GUI Tool is intended to generate binary images based on your configuration that are then used to directly flash the SPI Flash through a 3rd party flash programmer such as the Aardvark adapter.

    Your understanding here is correct. Although the FTDI is not needed for custom boards, you would need to implement a driver in order to communicate with TI GUI.

    TI does not provide this program. 

    Please let me know if you have additional questions/concerns.

    Hello,

    >Your understanding here is correct. Although the FTDI is not needed for custom boards, you would need to >implement a driver in order to communicate with TI GUI. 
    We will implement on board FTDI to facilitate our evaluation.
    Of course, we will consider whether we will implement on board FTDI for production stage, but we would like to implement this for evaluation stage.

    >TI does not provide this program. 
    According to our confirmation by using FT_Prog, it seems that there is no specific program on EEPROM (Almost region was "FF".)
    For EVM, which area did you program for FT4232HL ?
    (We think that we can use it as default setting if we imitate your EVM circuit.)

    I will check internally and get back to you by the end of the week.

    I don't think you need to program this. Please see other thread previous discussed on this. e2e.ti.com/.../4899700

    Hi Ghouse,

    I'm not sure why you described about below by refering your attached E2E link.

    >I don't think you need to program this.

    I checked your attached E2E link, but this thread talked only EEPROM for TPS65987, it seems that this did not talk about EEPROM for FTDI.
    Could you please clarify why you described about above ?

    Hi Ryuuichi,

    Aya is currently on leave, and I am helping support in the meantime. Apologies if any questions are repeated.

    We do not directly support the FT4232HL IC as it is not a TI part. Correct me if I'm wrong, but from my understanding, the part is a protocol interface tool that does not need programming?

    If you copied the FTDI circuit 1:1 from the EVM, you should be able to connect it to the GUI tool used with the EVM.

    If you are not using the GUI or did not copy it 1:1, you would need to write something custom to program the chip.

    As mentioned above, the FTDI does not need to be programmed.

    Thanks and Regards,

    Chris

    Hello Chris-san,

    Thank you for your reply.

    => Yes, I also have same understanding.

    If you copied the FTDI circuit 1:1 from the EVM, you should be able to connect it to the GUI tool used with the EVM.
    => Yes, our circuit connection between FTDI and TPS65987 is imitated your EVM.

    >If you are not using the GUI or did not copy it 1:1, you would need to write something custom to program the chip.
    => Understood.

    >As mentioned above, the FTDI does not need to be programmed.
    => Understood.
