MSP430FR59941: MSP430: Error connecting to the target: Unknown device

Part Number: MSP430FR59941

Hi,

For one project, we're using an MSP430FR59941 microcontroller.

The problem message "MSP430: Error connecting to the target: Unknown device" is displayed in the CCS IDE while debugging the controller code.

Microcontroller pins and JTEG pins are connected properly. A connection image is displayed below for verification.

how to solve the issue

Regard,

Vijay

    Hi Vijay,

    I don't see the image you attached, would you mind attaching it again so I can take a look? This error message is typically because of a wrong JTAG connection to the Target, or if there is a wrong R/C configuration at the RST/NMI pin.

    Best,
    Amruta
