No output from example_utils

Other Parts Discussed in Thread: SYSBIOS, TMDSICE3359, CC3100, MSP430F5529, CC3100SDK

There is no problem to import and build C:\ti\sysbios_ind_sdk_2.1.1.2\sdk\starterware\examples\example_utils project. However, there are some problems with debugging this project on a TMDSICE3359 board.

1. Regardless of where break points are set, whether they are in main() or in taskFxn(), the debugger doesn't stop anywhere. Is there any extra option to be set in order for the debugger to stop at the breakpoints?

2. Press F8 without breakpoints doesn't return anything. Why?

3. What hardware files are required?

4. How can we import the pinmux files into the project?

5. What libraries and dependency project are required to run this project?

I have been using FPGAs for quite long. Recently, I purchased a TMDSICE3359 board to evaluate possibilities to implement EtherCAT using AM335X. I really get stuck in the very early stage. I am not sure if I am confident enough to carry on with this. Lock of document and support is my biggest obstacle. I am not sure if this is a common problem for other TI customers.

Thanks for your help.

Stepping into taskFxn(), I found that CONSOLEUtilsInit() did return. The debugger stopped there.

Bailin,

1. In order to get the XDS100v2 USB debugger to set up and start breakpoints, make sure you load the .out file built with am335x_debug option (right click project in Project Explorer, then click Build Configurations->Set Active->am335x_debug), the .out file is located at sysbios_ind_sdk_2.1.1.2\sdk\examples\example_utils\am335x_debug\. To setup breakpoints, put the processor in halt state first.

2. Refer to 1.

3. No additional hardware files required to run the example_utils.

4. Refer to sdk\starterware\docs\Board_and_ChipDB_Details.pdf

5. No other libraries and dependency project required. You will see the output in UART console as below, and then just type the test number and press enter to run.

Hi Garrett,

Thank you very much for your reply.

Sorry, the example which I tested is actually C:\ti\sysbios_ind_sdk_2.1.1.2\sdk\examples\example_utils.

I successfully imported and built this project. However, debugging this project using "F8" (go) didn't produce any output on a uart console. Everything I did is exactly the same as you have told above.

Do I have to load .out file to the eval board manually? I believe that loading .out is covered by the debugger. Am I correct?

The debug configuration was set to the Code Composer Studio -Device Debugging. Is that OK? What extra options in the debugger configuration menus do I have to modify?

Regards,

Bailin

Bailin,

You must load .out file to the eval board manually, after you connect CortexA8 core, go to Run->Load->Load Program, and then select the .out file. After the .out file is loaded, the core will run to main() and halt if you use default JTAG debug option, and then you can set breakpoints to start debugging...

You don't need modify any debugger configuration to work with the project and CCS.

Hi Garrett,

Thank you very much.

There isn't Load->Load submenus in the Run menu. There are only 3 submenus in the Run menu. They are Debug F11, Debug History and debug Configurations... How can turn on those optional submenus?

Bailin

Bailin,

After you launch the target configuration, select 'CCS Debug' if you are in the 'CCS Edit' perspective. You need to switch to 'CCS Debug' perspective by clicking Window->Open Perspective->CCS Debug, or you may select from the top right corner of CCS window - 'CCS Edit' and 'CCS Debug'.

Hi Garrett,

Thanks.

Ok, the submenus of CCS Debug Run->Load are greyed out. However I noticed that .out was automatically loaded wen I pressed Run->Debug. The debugger stopped at { of Int Main(). Press F8 (go) didn't bring out any outputs on a uart console. I run different CCS projects in this way such as I2C_led of am335x_sysbios_ind_sdk_01.01.01.01. I didn't have a problem with debugging or output from a uart console. I think that there must be something else such as arguments or parameters which causes the problem. Maybe there are bugs which are platform dependent.

I have used different debuggers for many years such as Altera NIOS-II IDE but I have never seen this kind of problems.

Thank you very much for your patience. What do you think about jumper setting om the ICE2 evm board?

It actually gets stuck at Board_pinMuxConfig(am335xIceV2Mux) within taskFxn().

Bailin,

You are running the example on ICE v2 board, correct? The board marks: REV 2.1A.
SYSBIOSSDK-IND-SITARA 2.1.1.2 doesn't support ICE v1.

It is ICE V2 marked as Rev 2.1 Aon the board.

Does the uart port have to be com 1?

Hi Garrett,

Line 82 of pinmux.c, pPinmuxData = pBoardData->pPinmuxData raises an exception. I don't know why.

Hi Bailin,

If you set breakpoints at line 95, 101 of board_mux.c, and then 'Assembly Step Into' (Ctrl+shift+F5), do you see the same as the picture shows:

Do you have correct .out file auto-loaded? which is under am335x_debug/.

And do you have SD card plugged in the slot? If any, try to remove it.

Hi Garret,

The debugger doesn't stop at breakpoints. I moved them into main() and debugged it step by step to that point.

The .out was automatically loaded into the ICE2 eval board.

From pPinmuxData = pBoardData->pPinmuxData;, I can see the following by moving the mouse over it.

*(pBoardData) struct boardData

numDev unknown Memory map prevented reading 0x52679FC7

The other 7 elements appear in the same way.

It seems to me that the code tries to access unreachable memory space.

Many thanks and kind regards,

Bailin

Hi Garrett,

The ethernet_mac and ethercat examples both work here on ICE2 board (TMDSICE3359).

The getting_started_with_wlan_station, http_client and http_server examples in C:\ti\CC3100SDK_1.2.0\cc3100-sdk all work on CC3100 BoosterPack together with MSP430F5529 LaunchPad eval kit.

As a result, for example_utils, I don't think that there is anything wrong with the way software has been set up here or the way the code has been debugged here. There must be something wrong with the example itself.

If possible, can you please pass my questions and problems with getting example_utils working to the author or the related software design engineer of this example for help?

Many thanks,

Bailin

Bailin,

I certainly can pass your questions and problems to the developer of example_utils. Can you please attach your .out and .map files here so we can try to reproduce and solve the issue quickly?

If you click 'Reply' then 'use rich formatting' at right bottom, you will see a 'Insert File' icon for uploading files in the new opened 'reply' window.

Bailin,

Try to remove AM335x.lds from Properties->CCS General->Main tab (Linker command file:), that should resolve the problem.
