Unable to program MSP430F167

Other Parts Discussed in Thread: CC430F5137, MSP-FET, MSP430F167, MSP430F5510

I have built a board with the MSP430F167.  I am attempting to program it with CCS 6.1.2 with windows 10 and 7 (I have two computers).  At one point and time I was able to program the device with an MSP-FET 430 UIF and "Blown Security Fuse" came up.  Then if left connected it would max out the current of the 3.3V regulator.  I noticed the 47K resistor was not connected to 3.3v having the emulator directly connect 3.3v to gnd.  I started getting an unknown device error and assumed the debugger had fried.  I purchased a MSP-FET and installed the 47K resistor and get the same results.  I have a OLIMEX development board both FET can program, but it uses a 2 wire JTAG while I am using a 4-wire JTAG.  I have a board previously used on another project to it's completion, so I have a known good program and known good device (CC430F5137) using a 4-wire JTAG.  I cannot program it with either FET either.  I have searched the Forums and followed some recommended instructions.

1.  Test the communication between your computer and the FET (Programming tool).

both passed.  I was able to read both FET firmware versions using FET-Pro430

2.  Erase Flash on MSP430...failed

My schematic of the JTAG looks like this...

I have confirmed the pin-out and still unable to program the device.  What am I doing wrong?  Would connecting RST directly to 3.3V destroy the FET?  Can we try a two wire JTAG on this chip?

    Michael,

    I am unable to view the images you tried to upload, can you please post them again? I'm not sure about the MSP-FET430UIF but the MSP-FET uses ESD diodes that should prevent against reverse current damage to the FET tool. Additionally you fixed the RST short before attempting to program with the MSP-FET, correct? But if my understanding is correct you are now unable to program a CC430F5127 board with either FET tool which you've never had trouble with before? If you are able to program an OLIMEX board using 2-wire JTAG then that means the TEST and RST lines are fine, therefore the issue lies with the TDO/TDI/TCLK/TMS/TCK lines. Can you try programming your MSP430F167 board using 2-wire JTAG instead?

    I can try to repost the pictures.  The F167 does not have a test pin so therefore I cannont attempt to 2-wire JTAG.

    For some reason it is not allowing me to put pictures in this post so here is the data sheet for MSP430F167.  

    I have a 4-wire schematic exactly like the recommended schematic. 

    Except for the test wire is just an open connection.  According to note C it is only for multiple programming ports.  I will put an O-scope on TDO/TDI/TCLK/TMS/TCK and attempt to post it.

    My apologies Michael, I forgot that the MSP430F167 does not support SBW communication. If you could post the results from your o-scope findings that would be appreciated. Can you also provide a screenshot of the error that is displayed when you attempt to program the device?

    Here is the schematic of the programming port

    .

    Comm picture are as such. 

    CH1 - Yellow - TDO 

    CH2 - Blue - TDI

    CH3 - Purple - TMS

    CH4 - Green - TCK

    Now TMS looked very noisy so I zoomed in on the noise.

    And it was consistent.

    And the programming sequence.

    So continuing to bang my head against this problem I've tested the circuit again this morning.  The noise in TMS went away, but so did all signals.

    So I plug in the other programmer MSP-FET430UIF and got a different results.  Seems the TMS doesn't get driven high enough...

    Hi Michael,

    What Vcc is your external power supply operating at? What happens when you try to power the MSP430 device through the FET (using JTAG pin 2 instead of 4)?

    The system is powered by a 3.3V rail that I can see is 3.3. I will remove R23 from the system and solder a blue wire directly to pin 2 and try again and return with pictures.

    Using MSP-FET first leaving R23 installed and removing 3.3V rail regulator the voltage to the MSP430 was 1.08 V giving the following error upon any attempt to program it.

    Using the UIF same error occured.  Unknown device.  The rail voltage was 3.1V.  The O-Scope lite up as such...

    Is there a 2-pin JTAG capable MSP with a simular pinout?

    Any MSP430 device that is compatible with the MSP-TS430PM64 target board, in accordance with the MSP430 Hardware Tools User's Guide (SLAU278), should have a similar (but not exact) pinout. Do you not have any target boards, TI-provided or otherwise, to test with and confirm whether the 4-wire JTAG issues lies with the MSP430F167 custom board or the FET tools? I am trying to pull in a MSP-FET expert to comment on this matter but he is unfortunately not available this week.

    I have a MSP-EXPCC430RF board from TI, but unfortunately it has the FET installed on the board called the Debug Interface (very clever of you guys).  I do have a Wizzi-Kit designed by Wizzi-Lab () using a 4-wire FET interface using the CC430F5137 we modeled our DTRA board design after.  It too is an unknown device to CCS with a known good firmware and known good development board.

    So to recap I have a new board design (611), a known good personal design (DTRA), and a development kit (Wizzi-Kit) all using 4-wire JTAG, all have unknown device to CCS.  I have an Olmiexino-5510 with a MSP430F5510 using 2-wire JTAG that both FETs can program (annoying right?).

    In the interest of saving time I have ordered another MSP-FET430UIF to see if it could be the problem.

    It was the programming port. I purchased an MSP-FET340UIF and received it this morning. It work on the first try. Is the MSP-FET compatiable with 4-wire programming? Is it possible to exchange this MSP-FET if that is true? I'd like a second programmer for future developments.

    Hi Mike,

    The MSP-FET supports 4-wire programming. The error you mentioned before, where "The voltage 1086 value is not correct/allowed for the USB FET" is sometimes produced if the MSP-FET is oriented incorrectly. Have you confirmed that pin one of your JTAG header matches pin one of the MSP-FET device? You might try rotating the connection by 180 degrees to see if it produces any changes. Otherwise, you believe that the MSP-FET device you purchased was delivered already defective and has never worked?

    Regards,
    Ryan
