CCS 5.2.1 - Error Connecting to target, unknown device

Other Parts Discussed in Thread: MSP430F5438A

Hi folks,

I am using the MSP-FET430UIF for programming via JTAG into a custom target board based on MSP430F5438A.
The custom board is to be powered via the FET (PIN 2 is connected)

The error I get on programming is "Error connecting to target, unknown device".
I cant say I am 100 percent sure of my PCB, but I have checked in every possible way.
All the connections are as per the Hardware tools guide. Even the voltage from the FET is 3.2V. But still I am not able to program.

I have similar problem when programming the MSP-EXPF5438A experimenter board, when set to FET power.
The error given is "Failed to load program".
But when this experimenter is set to USB power, it can be programmed correctly.

I cant do the same in my custom target board.

Can someone point me in the direction of solving the problem? 
The firmware version on FET is 3.02.04.005

Regards
Shashank

    Hi Shashank,

    there was an earlier bug to do with power in our new v3 dll for the msp430.  My best recommendation is to do a full fresh installation of the latest version (v5.4) into a simple new directory like c:/myccs with antivirus disabled.

    Please keep us informed.

    Best Regards,

    Thanks Lisa for the input.

    I will do a fresh install and comeback.

    Meanwhile, I tried the same using FET ProLite (latest version 3.1)
    I also updated the firmware on FET430UIF to 3.02.05.004
    Is this the latest or does CCS 5.4 has newer version?

    Because it still gives me the same error, Now

    JTAG communication initialization.... OK
    Verifying Security Fuse .................... OK
    Erasing memory ............................... failed

    Also if I click the Power ON button on this software,, there is no response from the board?
    I am guessing its the dll problem, but is there any chance that this could be due to the software already present on the MCU?

    It has the Bluetopia stack on it?

    Hi Shashank,

    if ccs v5.4 does not help you, then I would also move to suspecting the code.  I say this because it almost looks like the memory might be protected.    Do you have an eval board or other board you can use?  This would help you verify.  You could also first try loading a provided example but the erase memory issue might pop up again ... so this is  a lesser suggestion

    - the FET and JTAG connection which seem ok from what you post

    - the hardware/software

    Failing that I would next say to post to the msp/bluetopia teams.

    Best Regards,
