MSP430FR2633: UART Example not working

Part Number: MSP430FR2633
Other Parts Discussed in Thread: MSP430FR2433

Hi MSP team.

I am trying out the UART example provided in the file msp430fr243x_euscia0_uart_01.c from here:

I am running on the Captivate EVM:

I debugging using CCS V7, using the Terminal in CCS with the following Settings:

The MSP430FR2633 isnt receiving any characters.

What have I done wrong?

    Hi Anders,

    The MSP430FR2633 on the EVM does not actually have a serial interface path back to the MSPFET programmer (aka backchannel uart).

    The UART/I2C from the MSP430FR2633 connect the HID bridge.  The reason for this is the 250K baud rate needed to communication with the Captivate design center could not be supported by the MSPFET programmer, so we included a HID bridge to support that requirment.  The UART signals do go to the boosterpack connectors so you could tap off the jumper block.  You will have to use another launchpad and connect to it's serial ports.

    In hind sight, there should have been a way to route the UART to the MSPFET.

    Another option would be to use the MSP430FR2433 launchpad.

    Hi Anders,
    I'm going to close this thread since it has been a few days since your last response and I'm assuming you have resolved your issue.
    If this is not the case and you need additional help, you can re-open this same thread.
