MSP430FR2153: MSP-FET flashing issue

Part Number: MSP430FR2153
Other Parts Discussed in Thread: MSP-FET, UNIFLASH

Hello,

I'm trying to program my microcontroler MSP430FR2153 with a MSP-FET Flash Emulation Tool.

The micro is powered by 2V3 and, in order to use the debug mode, I connected only VCC_TARGET, GND, TEST and RST pins between the micro and the MSP-FET.

With Code Composer Studio, I have the message "Error connecting to the target. Unknown device".

With UniFlash, I have the message "No debug probes/devices detected" and status "Inactive".

Should I use the VCC_TOOL pin instead of the VCC_TARGET ? As the MSP-FET will inject 3.3V on my board which is powered at 2.3V, it seems quite risky to me.

    Hey Alexian,

    Well, the Error from CCS is saying that it can't talk to the MSP430 (target) and the error from UniFlash is saying it can't take to the MSP-FET (debug probe.)  I'm guessing UniFlash can't talk to it because it was already busy/connected to CCS.  

    Anyway, is this a TI EVM or a custom board?  is the MSP-FET a stand alone programmer or are you jumping it from a Launchpad?  

    Not talking to the chip can have lots of causes but I encourage you to double check the power and then confirm the connections and circuit match the 2-wire JTAG circuit listed in Figure 2-3 of the MSP430 hardware tool's user guide.

    Thanks,

    DJ

    Hello,

    Thank you for your quick answer.

    We used Uniflash on a computer on which one CCS was not even installed and same way around (Uniflash never used on the CCS computer).

    Our board is a custom board, and the MSP-FET is a stand alone programmer directly connected to a USB port of our labtop (MSP-FET Hardware programming tool | TI.com).

    I'm pretty sure the problem comes from the power supply connection : I connected only the VCC_TARGET pin to the VCC of the microcontroler. Should I connect the VCC_TOOL either ? Or connect both pins to our board Vcc ?

    I connected my microcontroler power supply to both VCC_TOOL and VCC_TARGET pins of the MSP-FET.

    I also download the Windows installed version of Uniflash instead of using the web app.

    It is still not working, like with CCS I have the Error message "[ERROR] MSP430: Error connecting to the target: Unknown device" after ~10sec.

    Hello,

    I found the issue.

    On the MSP-FET connector, I used the pins "RST" and "TEST" which are the pins names of my MSP430FR2153 microcontroler.

    But the pins are also named "RST/NMI/SBWTDIO" and "TEST/SBWTCK", and we need to use the pins "TDO/TDI" and "TCK" of the MSP-FET.

    By the way, using the VCC_TARGET pin works perfectly and allow us to power are board and use debug mode.

    Best regards,

    Alexian
