    Hello,

    It is likely that the JTAG fuse has blown, setting the JTAG block to bypass mode. I would recommend testing your setup with a different device/EVM to see if the issue persists.

    For more reference, here is an older e2e thread that covers this same error on another device.

    Thank you,

    Susan

    Hello,

    Unfortunately, the MSP430I2041 does not come with a factory BSL. If your application included a BSL, then it might be possible to reprogram the device. However, if it does not, then there is no way to flash the device and can only be replaced to continue programming.

    Thank you,

    Susan
