Thread main function to Debug

HI Alejandro,

there are a few things I would like to double check first

- did you create a CCS Project?

- I notice you are not using the CCS Edit and CCS Debug perspectives.  These are what you should be using.

Please give this a try and keep us informed.

Best Regards,

Hi Lisa,

I use the Code Composer Studio for Windows XP. I have created a CSS Project and I'm using the debug view.

Thanks

Alejandro

Hi Alejandro,

please use the "CCS Debug" perspective.  Are you sure you specifically created File->New->CCS Project?  Any further details about your setup or the steps you are taking would help us to help you.

Hi Lisa,

For view the execution of the program when I debug I select: View -> Debug, but for debug I select: Target -> Debug Active Project.

Yes, I created my project with this steps: File -> New -> CCS Project.... The project type that I selected was ARM and Project Settings were the next: The device is the Cortex A8, the endianness is little, the linker command file is lnk32.cmd, and the runtime support library is rtsv7A8_A_le_n_eabi.lib (by default). Finally, I selected None in the option Target Content. The type of file generates is an executable.

I added the source file with this steps: over the project name: New -> Source File and I've named to this file (.c).
After that, I created the .ccxml file with this steps: on the project name: New -> Target Configuration File. In this file I selected the USB560 Blackhawk JTAG and the  OMAP3530.

I have modified some connection properties in the Target Configuration option of .ccxml file but I didn't got nothing.

When debugging should be created two threads: boot.c or boot.asm and main.c (main is the file that contains the function named main) but only appears the boot.asm thread.

Sometimes when I debug appears an error of "Finish Auto Run".

Thanks

Alejandro

HI Alejandro,

it looks like you code is not coming up halted at main, but rather running.   What if you press the debug button to launch?  Do you see the more expected behaviour?  (The debug button is the one that looks like a bug).  What if you deselect the "run to main" option?   This should make things halt at c_int00 and then you can try manually "Go to main" to see if that works.  Also ... have you verified you are using/selecting the correct GEL file for your target board?

Please keep us informed.

Hi Lisa,

Yes, the GEL file used is the correct, omap3530_cortexA.gel.

The program halts at c_int00, but the program should halt at main. However, the thread of main doesn't appear. If I press the button of bug, the program halts at thread c_int00, and if I press that button again the program halts at c_int00 again.

If I deselected the "Run to main" option when I debug happens the same. After, if I select the "Go to main" option nothing happens.

Moreover, a lot of memory locations contain the next value: BAD0BAD0.

Thanks
Alejandro

HI Alejandro,

are you using the GEL from the board manufacturer or the one in CCS?  Do you happen to be using the LogicPD board?  Are you using that GEL file if so?  Also if it is the LogicPD Zoom board, have you tried their getting started guide and hello world (found on their site).  Do these examples work as expected?

Best Regards,
Lisa

Hi Lisa,

I used the GEL file of the CCS. The example in the web of LogicPD doesn't works because the CCS doesn't found some files of this project.
I used the Zoom Omap35x board because it has a High-Density Breakout board with pins of GPMC bus which are necessary for the developmet of a project.

Thanks
Alejandro

Hi Alejandro,

is it the LogicPD board you have?  Did you follow their getting started step by step?   Can you provide any further information.

Best Regards,
Lisa

Hi Lisa,

Really I didn't install the CCS. I use the CCSv4.0.1.01001. The OS that I execute is the LoLo (LogicLoader)  which is installed in the NAND Flash Memory of the board.

I think that the problem could be with the main thread don't appear. I think that can that the boot.asm thread doesn't execute then the main thread can't appear.

Thanks,

Alejandro

Hi Alejandro,

have you been able to verify this is the problem?  Hav e you tried a standard non modified example?  Have you tried the latest CCS version?

Best Regards,
Lisa

Hi Lisa,

I think that this could be the cause of the problems, but I'm not sure. I'm trying execute the example of the getting started guide (the example "Hello world") but I can't execute it.

Now I can't intall the latest CCS version.

Moreover, sometimes get the following error: "Cortex_A8_0: Trouble Reading Memory Block at 0x80004328 on Page 0 of Length 0x2c: Error 0x20000008/-1066 Severe Error during: Break Point,  Cannot set/verify breakpoint at 0x8000432C" (The 0x8000432C address is the address of begin main function) when I put that address in the disassembly box view.

Thanks,

Alejandro
