MSP430F67791: Using the Energy Measurement Design Center with MSP-FET

Part Number: MSP430F67791
Other Parts Discussed in Thread: MSP-EXP430F5529LP, MSP-FET, MSP430F5529, UNIFLASH

Good afternoon,

I'm working with the EVM430-F6779 and I want to read and change the different clock settings (for example SMCLK and MCLK). As far as I understand, this should be done through the Energy Measurement Design Center.

In the Application User’s Guide, in the section “Program the MSP-EXP430F5529LP (HID Bridge)”, it looks like you need that board to configure the EVM. My question is: if I already have an MSP-FET, is the MSP-EXP430F5529LP (HID Bridge) still required, or can I configure the EVM using only the MSP-FET?

Thank you.

    Hi Nicolas,

    You can program the .out file with the MSP-FET as long as you have the JTAG connections. The HID bridge using the MSP430F5529 is for programming through the Isolation board if you were on a high voltage scenario. For example, if you were already attached to the Grid or poly-phase system. This is to protect your computer from getting zapped by the high-voltage/current rails, not a problem if you're not connected to the high voltage rails.

    I’m trying to load the example program EVM430-F6779_CT_3V_3C_60Hz.txt using the MSP-FET.

    When I start the download, UniFlash asks me to update the MSP-FET firmware. I followed the prompt and the firmware update completed, but after that the debugger stopped working.

    Now, every time I try to connect, I get the following errors:

    • MSP430: Error initializing emulator: MSP-FET / eZ-FET recovery failed

    • A dialog saying that one of the connected MSP-FET / eZ-FET debuggers needs recovery and asking me to click Recover.

    When I click Recover, the process fails and I end up with the same error again. I can’t program the board anymore. I don't know that to do Disappointed.

    Hi Nicolas,

    Can you try the cold boot process? See MSP Debugger's User's Guide page 23 section 5.6.5.3.

    Hi, the problem was solved when I used another laptop and performed the same procedure; the situation was a bit strange, but it worked.

    Hi Nicolas,

    Did the debugger update when you moved to the other laptop? Does it now work on the old laptop as well? If not, you might need a new driver for the MSP-FET on the "non-working" laptop.

    Regards,
    Luke
