MSP430F2131 "could not find device"

Other Parts Discussed in Thread: MSP430F2131

Hi all,

I've looked around a bit, but I'm not finding anything on my problem...

I'm trying to program an MSP430F2131 with my launchpad and CCSv5 on Windows 7.  I am connecting the VCC, TEST, RESET, and GROUND from the launchpad to the 2131.  When I hit debug, I get the error message "Could not find device (or device not supported)".  At first I suspected I wired it wrong, but after triple checking, trying on an F2132 (which worked fine), and trying on Linux with MSPDEBUG (same problem),  I am at the end of my troubleshooting rope.  Am I missing something? Do I need an update or a patch for CCS?  Any help is appreciated.

  • I saw in another post that the MSP430F2131 is a 4 wire JTAG only.  But I can't find the part of the datasheet that confirms this.  The test pin functions for the F2132 seem the same, but I can use Spi-bi-wire just fine with that one.  What's the difference between the two chips, other than RAM?  And where in the datasheet does it say that the F2131 is 4 wire JTAG only?

  • According to MSP430 Hardware Tools User's Guide (SLAU278L.pdf – Revised December 2012) page 13, LaunchPad-G2 can be used to program F20xx, F21x2, F22xx, G2x01, G2x11, G2x21, G2x31, G2x53.

    Note that F2131 is not in that list.

  • I see.  Well that's a bummer.  Thanks for the quick feedback.  Guess I'll just use more F2132s and solder carefully!

    Indeed, it is 4-wire JTAG only. And the datasheet of course doesn't contain information about what the device NOT has/supports. (else it would be the size of a library).

    The SBW protocol isn't mentioned as supported and there is no SBWTCK/SBWTDIO tag on the TEST/RST pins, so the SBW protocol, which the LaunchPad uses, isn't supported by this chip.
