LAUNCHXL-F28069M: Unable to Load Example Echo Code in CCSv620

The "test connection" aspect of the process is working correctly so we know that the JTAG connection to the device is good.

For the older projects you can right click on the project and pick "properties"  Go to General then products tab and remove XDIAS from the listing and recompile.

Can you try manually loading the program/coff file by right clicking on the .ccxml and "launch target config"  Then in the new dialogue right click on the C28x core and "connect".

Finally, Under the "Run" menu you'll want to load program you should be able to find by project.

Let me know if this you connected.

Best,

Matthew

Thank you so much！

I've conveyed it to the customer

Hi Matthew,

Many thanks for your help.

In Products I have both C2000ware 3.4.00 and XDCtools 3.32.1.22_core checked, is that OK or do I need to select 1?

Right click -> Launch Selected Configuration, under F28069M_XDS100v2.ccxml, it gives

- Texas Instruments XDSv2 USB Debug Probe_0/C28xx (Disconnected: Unknown)

- Texas Instruments XDSv2 USB Debug Probe_0/CLA_0 (Disconnected: Unknown)

You are required to terminate existing session -> OK

Run -> Load: No options available, all greyed out

I opened up Tera Term and put in what I believe to be the correct settings, 9600 Baud rate, 8 bit data, 1 bit stop bit (this may be incorrect?) and didn't see anything being returned at any stage of compilation. Any further suggestions would be great, thanks.

Best wishes,

James

James,

After they click OK to terminate the existing session, they need to right click on the

Texas Instruments XDSv2 USB Debug Probe_0/C28xx (Disconnected: Unknown)

and click connect.  This will either change the C28x to connected(and un-gray the run, load) or give an error in the console.  Please let me know.

Best,

Matthew

Hi Matthew，

Many thanks for your help. After right clicking and pressing Connect, I receive the following error messages:

For Boot Switch 1: On, On, Off

Error connecting to the target:

(Error -1135 @ 0x0)

The debug probe reported an error. Confirm debug probe configuration and connections, reset the debug probe, and retry the operation.

(Emulation package 6.0.407.3)

For Boot Switch 1: On, On, On

No source available for “0x3ff75b”

Hi James,

Matthew is out of the office for the next few days. He should be able to get back to you by Wednesday next week. 

In the mean time would it possible for you to try 'Wait Boot Mode'? The screenshot below is from the LAUNCHXL_F28069M User Guide

Best Regards,

Marlyn

Thank you so much！

Hello Marlyn,

Thanks for that. Putting in to Wait boot mode (Low, High, Low), and debugging, I get:

Error connecting to the target:

(Error -1135 @ 0x0)

The debug probe reported an error. Confirm debug probe configuration and connections, reset the debug probe, and retry the operation.

James,

Can we confirm that power jumpers JP1 and JP2 are populated.  This will power the MCU from the USB connection(debugger is powered even if these are not present).

Best,
Matthew

Hi Matthew,

I can confirm jumpers JP1 & JP2 are in place (note JP3 - 7 are also in place)

Interestingly, by removing JP2 twice over the course of a few seconds, just at the moment of debugging, I don't get the target not connected error but it looks like it might have compiled and I get:

Example_2806xSci_Echoback[Code Composer Studio - Device Debugging]

Texas Instruments XDS100v2 USB Debug Probe/C28xx(Suspended - SW Breakpoint)

  main() at Example_2806xSci_Echoback.c67 0x008521

  _args_main() at args_main.c:91 0x008675

  c_int00() at boot28.inc:223 0x0085DE (_c_int00 does not contain frame information)

  Texas Instruments XDS100v2 USB Debug Probe/CLA_0 (Disconnected : Unknown)

It still doesn’t seem to have given the helloworld message in TeraTerm while Tera Term is running on what I believe to be the correct settings and COM port.

Best wishes,

James

James,

Please try and remove JP7 (leave JP6 jumpered) and see if the UART will connect.

Best,
Matthew

Hi Matthew,

Thanks for that.

I remove JP7, and the board is recognised in both device manager under serial COM port and is recognised by Tera Term. When I debug in CCS v6.22, it seems to compile OK.

I push play button and no helloworld message in Tera Term.

I get the following warnings:

Description         Resource             Path       Location               Type

Build-variable 'XDAIS_CG_ROOT' cannot be resolved. The project may not build as expected.                Example_2806xSci_Echoback                     properties           Problems

Invalid project path: Include path not found (\packages\ti\xdais).              Example_2806xSci_Echoback                     pathentry            Path Entry Problem

Right click on project -> Properties -> Products tab, I don't see the XDAIS as I thought I might have (I have unchecked in the past when seeing  similar error). I see C2000Ware 3.4.0.00 and XDCtools 3.32.1.22_core all checked.

Best wishes,

James

James,

Even with the warning I think the code should compile, generate a .out file in the /debug directory.  Can you confirm if this is true?

Can we go back to the first few replies I sent for this thread, and customer confirm that they can manually connect to the device using right click of CCXML Launch Selected Target Config.  For this I don't want to load any code, just make sure they can connect to the MCU through JTAG.

Another thing to try would be to get the C2000Ware package and find the same example in that install, this would have the most up to date includes, etc.

Best,
Matthew
