AWR1843BOOST: could not connect to the device using tera term

Hi Vimal,

If you are able to flash the binary to device using UniFlash (over COM13) then you should able to connect it (over same COM port) while OOB demo is running in SOP-4 (functional mode).

While you are trying to connect from TeraTerm, make sure that you have closed the visualizer and Uniflash & reconnected the USB cable (to break any blocked COM handle).

I don't see any other real cause behind this issue.

Hi Jitendra,

after restarting system i can able to open the COM port.

But the issue is, when the device is in debug session in CCS ,i plugged out the USB cable, after that if i plug in i cannot able to connect to COM port.

what do i need to do to connect the COM port and i do not want to restart my system.

Even i tried changing COM port number manually in device manager but still i face the same issue.i checked with demo visualizer also it says serial port already opened.

some of my applications is being connected to the COM port even i closed all the applications

Thanks,

Hi,

now i restarted my system,i tried flashing in uniflash in the flash mode,i can flash the image.

then i closed the uniflash application and changed to functional mode and restarted the device and tried to connect to demo visualizer and teraterm ,it couldn't connect.

but i can able debug my code in CCS .after debugging in CCS ,now i couldn't connect with uniflash also.still wondering what was is the problem.

Hi Jitendra,

any leads on this,so that i can fix my problem.

Hi Vimal,

If you are trying to connect Visualizer and TeraTerm both at the same time then you can't do that. And for Visualizer I hope you are using Chrome (latest version) and installed the required extension and TI Cloud agent.

And could you tell us the reason for using TeraTerm with mmw demo?

While using uniflash you need to disconnect CCS from the device (JTAG connection) and may need to un-plug/plug the USB cable (if issue persists).

If you were able to flash the binary to the device using Uniflash then that proves that PC is able to access the COM port; same COM port is being used by Visualizer for CLI command (Rx/Tx).

This is a very strange issue that Uniflash connection works but not visualizer/TeraTerm.

Hi,

I know that i cannot connect Visualizer and TeraTerm at the same time.

i can able to flash the binary to the device using uniflash,i can connect to teraterm and i can connect visualizer, But

 after some time i cannot connect to anything either uniflash,teraterm or visualizer.i need to restart my system again to connect to com port.some application is getting connected with the COM port.

the reason i'm using teraterm with mmwdemo is to see the data what exactly it is sending and once i figure out the data,i will be sending data over CANFD ,thats my thing as of now.

Thanks
