my debuger is www.ti.com/.../TMDSEMU110-U

useing case just like like Debug / JTAG Probe - XDS110: UART and Utility GPIO - Blog - Embedded - element14 Community

this is how i connected.

Can you please give some more details on your question or issue? The connection you provided from the XDS110 is correct for the UART, you should see this enumerated in your OS system list.

hello Matthew

yes,i can see two COM ports in my OS.i used serial debug tool to open two device,but they can't write to each other.my serial tool device signal level is 3.3V.

what i want to complete is using XDS110 DEBUG PEROBE device to transmit CMD.

here is my debug tool interface on OS

What is the receiving device you are communicating to. Is this a C2000 MCU, or other TI MCU? I'd like to make sure I get this routed to the correct engineers.

the receiver is not a MCU, i used my UART tool just like this picture to receive XDS110 debug probe,this device's signal level is 3.3v and i had been used it to transmit message to MCU.

Hu,

From what I can find I believe these are the settings for the UART from the XDS110

Baud = 115200

Data Bits = 8

Parity = None

Stop Bits = 1

Can you make sure that is how the receiver is configured? I'm not aware of any changes that can be made to the XDS110 side in this regard, although there may be some command line options.

Best,

Matthew

the setting for Rx device is same,Baud =115200,Data Bits = 8, Parity =None Stop Bits=1.

Hu,

Looking at the picture I think you need to swap the jumper wires on either the XDS110 break board or the other PCB. TX from the XDS110 should go to Rx on the blue PCB and Rx from the XDS110 should go to Tx to the blue PCB.

Right now it looks like Tx goes to Tx and Rx goes to Rx, which is incorrect.

Best,

Matthew

i had swaped TX and Rx,but it is not worked.

hellow Matthew,

did you have use case, like video or picture

There is this video, https://www.youtube.com/watch?v=GV1h61JyzcE connecting to the UART of the TI MCU. They are using the terminal inside CCS, but I don't believe that is a requirement.
