MSP430F6749A: MSP-FET Flash Emulation Tool

Other Parts Discussed in Thread: MSP430F6749A, MSP-GANG, MSPDS, MSP-FET, MSP430-FLASHER

art Number: MSP430F6749A

Currently, I am using IAR EW430 version 6.30.1, with a MSP-FETFlash Emulation Tool to download and debug into the MCU. The problem I am facing is that every time I try to download into the MCU, I get this error:

 

Fri Feb 01, 2019 15:17:11: Fatal error: Failed to set device voltage.   Session aborted!

 

To troubleshoot if it’s a hardware issue, I’ve used the same wires and adapter pin configuration on the MSP-GANG programmer and I can successfully download my program into the MCU.

 

I also have managed to download into the MCU previously, on a different laptop with the same IAR EW430 version 6.30.1 with the same MSP-FETFlash emulation tool, where serial number starts with 17

I've seen this article:

where it states to upgrade IDE as version 6.40 below with fet flash tool starting with 17 will lead to this error but I managed to do it last time on a windows 7 laptop with the same equipment. 

Do you have any solutions for this as we cant upgrade IDE

Thanks

  • Hello,

    Unfortunately, the article link didn't show up in your post. The preferred solution would be to upgrade to the latest version of IAR. The only alternatives that come to mind would be to (1) downgrade your MSPDS to an older version [EDIT: Option 1 may not work since this is a "new" MSP-FET starting with 17 and MSPDS versions older than v3.9.2.15 may not support this new hardware] or (2) use a MSP-FET with a serial number less than 17. For option 1, read through the following threads that talk about doing this. The versions may be different between the working versus non-working laptops. 

    Last but not least, make sure your JTAG circuitry matches our recommendations in the MSP430™ Hardware Tools User's Guide. While the MSP-GANG may work, the MSP-FET may not if the guidelines aren't followed.

  • Hi James,

    Thanks for your reply, I did go through the 2 attached links, seems like the second link has the exact same error log as me

    I did try the solution on the link to try to update my MSP FET where i downloaded MSP430-Flasher that has the same MSPDS version as my current setup whic his 3.4.3.4, but to no avail. 

    Here is the log from the MSP430-FLASHER

    How do i trigger the MSP flasher to update my MSPFET?

  • Hi Jack,

    Thanks for the additional details. I'm not very hopeful that we'll be able to get your MSP-FET (serial number starting with 17 or higher) to work with your IAR v6.30.1 since it's not officially supported.

    [FAQ] MSP-FET: SOLUTION: Using newer MSP-FETs with older CCS or IAR versions

    As shown on IAR's website, IAR Version 7.10.1 adds support for the new MSP-FET (serial number starting with 17 or higher) using through v3.9.2.15 of the msp430.dll.

    Release notes for the MSP430 IAR Embedded Workbench product package version 7.12.1

    Perhaps you could try updating your MSP-FET to this version, but I'm not confident it'll work. You could try downloading and installing the MSP430Flasher  v1_03_12_00 (which includes MSP Debug Stack v3.9.2.15) and then try updating your MSP-FET firmware. I suspect your existing version of MSP430Flasher isn't updating the MSP-FET's firmware since they're the same version.

    Regards,

    James
