MSP430FR5994: cannot show output in terminal when using mspdebug to run a program on msp430FR5994

Hi,

I'm first to use the mspdebug to deploy a DNN on msp430FR5994. After I successfully flash the executable to the board, I try to run it on the board but there is no output shown in the terminal( Actually in the original code there are some printf sentences, and I think the print output may appear in the terminal in expectation). Even though I try to using screen command to capture some information via the serial port, there is no information but there are some garbled code shown when I flash the program to the board and enter ctrl+c to interrupt the program.

Hi Kimi,

Considering there is no information in serial port, so I assume that the configuration of the serial communication peripheral may have some mistakes. I will apply the reference code for checking details if you can tell me which communication peripheral you use.

Best Regards

It isn't clear from your description how you are trying to see the serial data. You must have a terminal program running (I use minicom) and connected to the correct tty with appropriate settings.

Hi Sal,

Thank you for your reply I use usb to connect the msp430fr5994 with my pc and use "screen /dev/ttyACM0 9600" command to get the serial port connection.

This picture shows what happens when I flash executable to board and run it.

The reference code is https://github.com/CMUAbstract/SONIC.

Thanks.

Hi David,

I use the "screen /dev/ttyACM0 9600" command to get the serial port connection.

Thanks

I never heard of "screen" but I use ttyACM1 to talk to my Launchpad. ttyACM0 is the port used by mspdebug.

Hi all,

I have solved the problem by doing it on ccstudio. Thank you for your replys.

Thanks
