Original question:

MSP-FET: MSP FET driver problem

MSP-FET: Error with IAR workbench 7.12. Can't find the device

Part Number: MSP-FET
Other Parts Discussed in Thread: MSP430G2432,

Hello,

I'm using IAR workbench for our MSP projects. Changed emulator tool from Olimex (which works wonderfully) to TI's MSP-FET when we upgraded IAR workbench from version 6 to 7. Problem is that MSP-FET doesn't work: Get: "Fatal error: Couldn't find the device". I've connected it according to the user's guide: external Vcc (3.3 V), pin 1 to RST on the target (MSP430G2432) , pin 7 to TEST on target, pin 4 to Vcc -target (3.3V), pin 9 to GND, 

Have reported error to IAR but they don't know. The IAR workbench do communicate with the emulator - first thing it did was to upgrade firmware, but no luck after that. 

Anyone who knows?

    Hi Magnus,

    • Make sure the MSP-FET is plugged into a USB 2.0 port and plugged directly into your computer. (Not USB3.0 and Not a USB-Hub)
    • Make sure you have only 1 programmer plugged into your computer at a time
    • Check and to follow page 19, section 5.6.5.1-2 on the MSP debuggers user's guide to make sure the JTAG connector is configured correctly
    • What version of IAR workbench are you running?

    Hello Chris,

    Haven't heard before that MSP-FET can't handle USB 3. Not sure how to solve that. My development PC is a DELL Precision 7520 and it uses only USB 3.0's, no old USB's. Seems strange that TI' only development tool for MSP430 can't run on sate-of-art machines. You sure?

    Hi Magnus, we've seen this issue with previous posters on this forum, and using a USB 2.0 port solves the issue.

    Do you have another computer with a USB 2.0 port to test if this fixes your issue?

    Hi Christopher

    After lengthy discussions with IAR (who were very helpful), the solution came suddenly and unexpectedly. Problem was caused by a typo error. TI's manual "slau278ae.pdf" shows how to connect the MSP-FET for MSP430 Fxxxx and G2xxx  (see page 22, Fig 2.2). DO NOT FOLLOW THAT if you use these MSP's. If you still do, you'll end up with "Fatal error: Couldn't find the device". INSTEAD, connect the MSP-FET according to Figure 2.3 on page 23 (although the text says Fig 2.3 shouldn't be used for G and F series).

    I guess this all comes down to a typo error from TI's side but hopefully this post will save some time for others. Finally, don't bother about USB 2 or 3. Connect according to Fig 2.3 and it works for both.

    Best reg Magnus B
