EVM430-FR6047: Inquiry Regarding Firmware Programming for Custom EVM430FR6047-Based Circuit Board

Hi,LuKe

Thank you for your response; it is indeed very helpful. I will be sure to share any new developments with you.

Hi,Luke

I encountered some delays and only received a new FET430UIF programmer this Monday for flashing the firmware.

To summarize my process:
1. I programmed the MSP430F5529 chips using UniFlash with the following firmware files:
`TI_MSP_HIDBRIDGE__1_00_03_00__BANSHEE-USS-EVM.txt` (for the HID bridge functionality)

 `EZFET_LITE_Rev1_1_BSL_1_1.txt` (for the EZFET debugger)

However, after successfully flashing the firmware, connecting the board to my PC results in:
- A "USB device not recognized" error
- No corresponding COM port appearing in Device Manager
- CCS failing to detect any FET device (where I expected it to recognize the board and potentially update firmware automatically)

As a beginner, I'm uncertain whether my configuration or approach is correct.

I initially attempted this process using CCS v12.04, and subsequently upgraded to CCS v20.1.1, yet the device remains undetected.

While researching this issue, I encountered a similar case in https://e2echina.ti.com/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/192511/ez-fet. However, updating the Visual C++ drivers did not resolve the problem.

I would greatly appreciate your insights on:
1. Potential causes for the USB recognition failure
2. Whether my firmware selection and flashing procedure were appropriate
3. Recommended troubleshooting steps

Thank you for your assistance.

The uniflash program was stating the flash was successful, are you able to read the memory back to verify it has been programmed? 

You can also try one of our simpler USB example codes for the F552x, they should allow the device to be detected through the device manager. https://dev.ti.com/tirex/explore/node?node=A__ACXilaMBGWxmMPravPVz2Q__msp430ware__IOGqZri__LATEST&search=F5529 

This will help abstract if there's a USB or HW connection issue or if the EZ-FET firmware isn't operating properly.

Hi,luke

Wonderful answer, this completely solved my problem.

After successfully programming both boards with the COM firmware, I observed that while the HID functionality (MSP430F5529) operates correctly, the EZFET debugger initially failed. Upon careful circuit inspection, I discovered I had mistakenly reversed the DM and DP interfaces - an oversight I've since corrected. Currently, while intermittent "unrecognized USB device" notifications persist, I've achieved successful communication between my custom board and the host PC.

When connecting the EVM430FR6047 evaluation board to my PC, two COM ports appear ("MSP Debug Interface" and "MSP Application UART"), provided by the EZ-FET’s dual USB interfaces (debug + UART). However, with my HID device (5529), no COM ports are detected—instead, two new HID devices appear. Could you clarify:

1. Though the 5529 and FR6047 communicate via I2C, the J1 header still exposes TX/RX pins. Could you clarify their purpose?

1. Without the EZ-FET, can I use these TX/RX pins for transparent UART communication with the MSP430FR6047 (similar to the EZ-FET’s functionality)?

I’d like to modify the HID code in the 5529. Could you advise:

1. Is USS-specific HID source code available?
2. If not, which of the provided HID example codes most closely resembles the firmware used in this application?

Your guidance would be greatly appreciated.

I'll need a bit of time to answer your questions, I should be able to get back to you on Wednesday for all 4 of the questions.

Hello, do you have any updates to share with me? I look forward to your reply.
