TMS320F2800157: Best approach for developing a GUI-based firmware reprogramming tool for F2800157 using Serial Flash Programmer

Md Kamarudheen

Part Number: TMS320F2800157
Other Parts Discussed in Thread: UNIFLASH

Hi TI Team,

I am working with the TMS320F2800157 and would like to develop a Windows GUI-based firmware reprogramming tool for end users.

My current understanding is that I can use the TI Serial Flash Programmer as the backend and develop my own GUI frontend that invokes it for programming the device over the SCI bootloader (using an RS-485 interface).

I would appreciate your guidance on the following:

  1. Is using the TI Serial Flash Programmer as the backend with a custom GUI frontend the recommended approach?
  2. Does TI provide any ready-made GUI application for SCI/Serial Flash Programming of the F2800157?
  3. If not, are there any TI-recommended open-source or GitHub projects that provide a GUI for the Serial Flash Programmer?
  4. Is there any TI library or API that can be integrated directly into a custom GUI instead of invoking the command-line executable?
  5. From a development time and maintenance perspective, what approach would TI recommend for building a professional firmware update tool for customers?

  6. My goal is to develop a reliable, easy-to-use firmware update application with minimal development time while following TI's recommended practices.

    Thank you for your guidance.

thanks & Regards

    Hi Kamarudheen,

    Please have a look at the uniflash tool - UNIFLASH Software programming tool | TI.com

    Here is some supporting videos  - Getting started with TI UniFlash tool with MCU_PLUS_SDK | Video | TI.com

    Let me know if i answered your question.

    Thanks

    Hi Aswin,

    Thank you for your response.

    My use case is slightly different from programming through an XDS debug probe.

    My hardware setup is:

    TMS320F2800157

    SCI Bootloader

    SP485 RS-485 transceiver connected to the MCU SCI pins

    FTDI USB-to-RS485 converter connected to the PC

    The firmware update will be performed over the fixed RS-485 communication interface in the field, without using an XDS debugger.

    Because of this, I believe TI UniFlash may not be applicable, as it appears to be intended for JTAG/XDS-based programming.

    Could you please clarify the following?

    Is the TI Serial Flash Programmer the recommended solution for SCI bootloader programming over an RS-485 interface?

    Does TI provide any GUI-based version of the Serial Flash Programmer, or is the command-line tool the only supported option?

    For a customer-facing firmware update application, is TI's recommended approach to develop a custom GUI that invokes the Serial Flash Programmer in the background?

    Thank you for your guidance.

    Best Regards,

    Md Kamarudheen

    The serial flash programmer is our recommended starting point. You can make modifications as needed to meet your requirements.

    TI only provides the CLI tool.

    This is up to you and your customers' requirements.

    Best,
