CCS/CC3220SF-LAUNCHXL: Cannot connect to the target

Mritunjoy Das

Part Number: CC3220SF-LAUNCHXL
Other Parts Discussed in Thread: UNIFLASH,

Tool/software: Code Composer Studio

I tried to debug a inbuilt example of ccs in TI CC3220-SF Launchpad but the board is not getting connected.

The error says-''cannot connect to the target" error 1170.

I saw that this problem occured with many users so tried to solve by trying the solutions already posted in the ti forum but no use

I have tried all the solutions given for such issues in TI Forum.

The board getting programmed by uniflash but not through comde composer studio.

I have also checked the jumper settings.

What could be the problem?

Hi,

Did you switched your board into development mode using Uniflash software? Do you have set proper target configuration in CCS according your SOP configuration?

Please post here photo of your LaunchPad to determine that your jumper configuration is correct.

Hi,

Jumpers settings looks OK. In case of error -1170 is returned from CCS, it si likely that you not have set development mode in Unilfash. Please see link at my first answer and make sure that development mode is set.

Hi,

It seems that you have communication problem between Uniflash and CC3220 chip. Reasons of this issue may to be:
- not properly installed drives for XDS-110 debugger
- occupied COM port by some 3rd party software
- not properly set UART (RX, TX pins at LaunchPad) ... it does not look that this your case, according image above
- wrong SOP configuration ... it does not look that this your case, according image above

Please follow this step:
- please check at Windows device manager that you see COM ports (XDS110 Class Application/User UART and XDS110 Class Auxiliary Data Port)
- please make sure that COM port is not occupied by 3rd party software (Tera term, Terminal at CCS, etc.)
- Disconnect USB cable from LaunchPad and change SOP jumper from mode 010 to mode 100 (2-1-0). Make sure that jumpers marked RX, TX are properly populated. Connect USB again to LaunchPad.
- run Uniflash and check that XDS110 USB Debug Probe is properly detected. You should see this at first page. After that select CC3220SF-LAUNCHXL (serial) and start image creator. Open/create project in development mode and try connect.
- Check current mode, make required settings and program new image.
