MSP430F2619S-HT: High Temperature chip not programming with CCS, JTAG - Wrong Family User Guide ?

MATHEUS MENDES

Part Number: MSP430F2619

Tool/software: Code Composer Studio

I´m in the middle of a project that needs to communicate two MSP430F2619, I´ve made two pcbs, one with the MSP430F2619TPM (usual), that works fine, and another one that uses the MSP430F2619SPM (high temperature rated version) which simply does not connect to CCS.
In futher inspection i realized that the TI part site says that the family user guide to use with this F2619SPM is the x5xx or the x6xx families (www.ti.com/.../MSP430F2619S-HT) which is really odd and mind boggling to me. 



I´ve tried the following:

-Replace chip for a brand new one.

-Test JTAG (RST, TDI,TDO...) traces from connector to chip.

-Check voltage levels, AVcc and DVcc.

Ps.: the project needs to be HT rated, so I really need to use te SPM variant.

    Hello Matheus,

    did you tried to handle MSP430F2619S-HT as a regular MSP430F2619?
    On a software level they should be compatible.

    I used the F2619S some years ago (we wanted KGD, and the "S" was what they had), and I programmed it with an ordinary USB-FET box, as though it were a non-S. (It can't do SBW, but that's the same as the F2619.)

    I used IAR since at the time CCS was more of a, um, "concept". I don't recall any special concerns about the circuitry, but it's been a while.

    Unfortunately, "Unknown device" can mean almost anything. Double check your bypass caps and Reset pin conditioning.

    Those links to the F5 User Guide are indeed rather odd. Use the F2 User Guide from the F2619 (no S) page.

    Hi Matheus,

    sorry for the confusion, as by Bruce already please use the MSP430x2xx User's Guide, it seems the wrong one is linked to the F2619S- HT product page. I'm going to have that fixed though.

    I understand from your post that you've successfully programmed and debug the non-S version. Did you use the same tools for it? If not, could you please try that to rule out that there's an issue with the debugger or cable?

    Can you confirm that the two PCBs are equal except for the MSP device? Could you have an issue with the power supply on the PCB containing the F2619S-HT? Could you try replacing the chip with a non-S version? If the problem persists it's nit linked to the S version, if not, it might be some kind of tool mismatch (due to the S version).

    As Bruce said, there are a lot of possible reasons for this issue so please bear with us asking all those questions.

    Best regards,

    Britta

    Hello Britta and everyone,

    I´ve got a hold on a MSP - TS430PM64 dev board, and with it was able to successfully program both the S and non-S version.
    On further inspection I de-soldered the chip of the board, and tested pin by pin the electrical connection of the traces, bingo! That was the problem, TDO line was shorted to XT2IN pin.

    Given the PCB manufacturer I used is reliable, probably it happened during the solder job and somehow passed QC.

    The other board manufactured at the same time, and soldered at the same place, is working fine, so I thought the problem was the wrong family user guide.

    Thank you all for the help
    Best Regards
