Error connecting to the target:No MSP430 device found on USB FET1

Other Parts Discussed in Thread: MSP430F5514, CCSTUDIO

We have an MSP430F5514 chip & we are unable to establish JTAG communications with the part.

The part is getting +3.3V DC.

The part is connected on the board as shown in the document SLAU278E, page 27.

Code composer gives the error "Error connecting to the target: No MSP430 device found on USB FET1"

The JTAG clock & TDI lines is showing activity. However, we don't see activity on the TDO.

Out target hardware uses the internal DCO and does not provide any external crystal or oscillator.

We are able to disconnect the FET from our board and successfully program a 5514 using the MSP-TS430RGC64USB eval board.

Any tips or suggestions?

    I personally was never able to get the MSP430F5 family of chips to program using IAR (version 4.11) and the Spy-bi-Wire interface, but I was able to program them using CCStudio and the Spy-bi-Wire interface, same exact hardware in both cases.  Other than that, make sure that your RST pin is pulled high (R1 from SLAU278E page 27) with only a small capacitance, if any at all, on the RST line.

    Hi Danimal,

    General hints are: do you have any caps on the JTAG lines? How about pull-up or pull down resistors? Have you taken care about the Vcc feedback line to the interface?

    Anyway, here's a general, software related item:

    I guess you care using the MSP-FET430UIF interface. If so, do you have the F5514 and the UIF interface connected to the PC at the same time? The current IAR version and CCSv4.1.3 and older may have issues connecting to the device if the F55xx and the UIF are connected to the same USB hub.

    This issue was resolved in CCSv4.2 (Release Candidate was just posted to CCS wiki). IAR KickStart will appear on the web in the next days.

    Hope this helps!
