CCS/TMS320F28335: Trouble Halting Target CPU

user6037567

Part Number: TMS320F28335
Other Parts Discussed in Thread: C2000WARE, TMDSCNCD28335,

Tool/software: Code Composer Studio

Suddenly I got this error and couldn't do anything. Before that, it worked fine. First of all, I noticed something wrong with Simulink, and when I checked it with CCS, I encountered this error. I'm working on debugging this, and I think something went wrong after I changed the Oscillator Clock.

Error details ↓
C28xx: Trouble Halting Target CPU: (Error -1138 @ 0x6) Device refused to allow debug mode. Power-cycle the board. If error persists, confirm configuration and / or try more reliable JTAG settings (eg lower TCLK). (Emulation package) 9.2.0.00002)
C28xx: Error: (Error -1141 @ 0x0) Device is not responding to the request. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and / or try more reliable JTAG settings ( eg lower TCLK). (Emulation package 9.2.0.00002)
C28xx: Unable to determine target status after 20 attempts
C28xx: Failed to remove the debug state from the target before disconnecting. There may still be breakpoint op-codes embedded in program memory. It is recommended that you reset the emulator before you connect and reload your program before you continue debugging
C28xx: GEL: Error while executing OnTargetConnect (): Could not read register ST1: target is not connected
at (ST1 & ~ (0x0100)) [f28335.gel: 322]
at C28x_Mode () [f28335.gel: 82]
at OnTargetConnect ()

I searched for it here, but I couldn't find a solution.

Thanks.

Please clarify what board you are using. Based on your other post, I presume you are using https://www.ti.com/tool/TMDSDOCK28335.

Are you able to connect to CCS? That is, without involving Simulink, are you able to simply connect to CCS?

What exactly do you mean by “after I changed the Oscillator Clock”? Referring to the schematics in C:\ti\c2000\C2000Ware_3_03_00_00\boards\controlCARDs\TMDSCNCD28335\F28335controlCARD_HWDevPkg_ZJZ_[R1.2], did you actually change the crystal X1?

If you are new to C2000 or CCS, please review the workshops at https://training.ti.com/c2000-mcu-device-workshops. TI has invested considerable resources to develop these self-paced workshops and most questions can be answered by reviewing the workshop material for your specific device family or its closest equivalent. The workshops are an excellent introduction to the basics of C2000 MCUs and the process of writing and running your first example. Good introductory videos about CCS are available at https://www.youtube.com/user/CodeComposerStudio.

Hello
Thank you for your quick reply.

I am using TMS320F28335, Docking-Stn [R3], MATLAB (R2020b), and CCS10.

It is this part that has changed on Simulink. (From 30 to 10)
After this, even if I restore it and build it, an error occurs.

The test connection is successful with CCS.

When I press debug, the following message appears and I can't proceed any further.

Thank you

For Simulink questions, please post it on the Mathworks forum. I regret I am not familiar with Simulink and cannot help you further.

If the test connection is successful, you still need to connect to the target in the Debug perspective. More help is available in the links I had sent earlier.

Hi!

Press "OK" on the third image of the reply to close the debug perspective. And you can only click OK.

Thanks.

When you have successfully connected to the target, you should see the image shown. Did you watch the CCS videos on YouTube? Also refer to http://www.ti.com/lit/spracf0. This document has all the information you need for JTAG debug.
