Problems programming/debugging the MSP-EXP430FR5739 with MSP-FET tool

Other Parts Discussed in Thread: MSP-FET, MSP-EXP430FR5739

Dear All, 

I am sorry if this question has already been posted. I have found some threads with a similar question, but I have been unable to solve my problem.

I recently purchased a MSP-FET tool to program the MSP-EXP430FR5739 and measure power consumption. I have followed the MSP-FET user's guide to install the hardware in my machine and connected the MSP-FET to the experimenter board as follows (see also image):

MSP-FET MSP-EXP430FR5739
TDD/TDI (Pin 1) RST/NMI/SBWTDIO (Pin 20 --> TP15)
TCK (Pin 7) TEST/SBWTCK (Pin19 --> TP14)
VCC_TOOL (Pin 2) MSP_PWR jumper pin
GND (Pin 9) GND jumper pin

Please notice that I have disconnected the eZ-430 programmer/debugger (J3 jumpers). 

I am using Code Composer Studio version 6.1.1.00022 (latest update), installed on a Windows 8.1 (virtual machine).

When connecting the MSP-FET, I can see it is correctly installed in Control Panel, Device Manager, Ports (COM & LPT), where:  

  • MSP Application UART1 (COM5)
  • MSP Debug Interface (COM6)

Just in case, I can program the experimenter board through the eZ-430 programmer/debugger with no problems.

The problem is that, when pressing the debug button, CCS configures the debugger (figure 2) and then it shows the following error message (figure 3):

I suspected it was a problem with the wiring (as shown in the figure 1), so I checked all the connections and even tried a different configuration. Also, as suggested in some other link, I externally powered the experimenter board (3.3 V DC), and at least I could see how the board started working (as expected), as this wasn't happening just connecting the board to MSP-FET. 

I hope all this information helps guess what I am possibly doing wrong. I would appreciate any help at your earliest convenience. Many thanks

Best wishes, 

David

    Hi David,

    Your JTAG connections seem completely flipped based on the picture you provided. The while cable line and small arrow on the JTAG connector indicate where pin 1 is located. I apologize for the confusion caused by the image on the MSP-FET, it represents the connections as viewed from the top of the JTAG connector instead of the bottom like you expected.

    Regards,
    Ryan

    Hi Ryan,

    So simple and I didn't realise that minor detail... It now works. Many thanks.

    Best wishes,

    David
