RTOS/BEAGLEBK: Adding breakpoint to my application

Vishav Vishav

Part Number: BEAGLEBK

Tool/software: TI-RTOS

Hi,

I have rebuilt my NDK in debug mode so that I can debug my application better. I want to add a breakpoint in fdt/ipout.c at function LLITxIpPacket function. I know that my app calls this function (I figured it out after stepping in and stepping over). But when I try to set a breakpoint on this line I get a warning:

No code is associated with "fdt/ipout.c", line 447 in "workspace/myapp/Debug/myapp.out"

Is there any way to overcome this? It would make my debugging faster.

Here are the details of tools that I am using:

EDMA3 Low Level Driver 2.12.5

NDK 3.40.1.01

SYS/BIOS 6.73.1.01

am335x PDK 1.0.13

xdctools_3_51_01_18

Hi Vishav,

As a fellow CCS user, I've also had some issues with breakpoints being set. The way I've gotten them to work, is to wait to add them until after I've loaded the program onto the appropriate core. This loads the "myapp.out" reference that is missing in your error posted above. Additionally, the breakpoint view (View -> Breakpoints) will help you see if they are set properly & active.

Please mark this thread as resolved if I've answered your question.

Thank you,
Alec

Hi,

Thanks for reply. But I am sorry as this doesn't answer my question. I am aware about what you said. Please refer to the picture attached to understand my issue better. When I am trying to enable a breakpoint marked in red circle, I get a popup window saying no code is associated with my output file. Do you have any ideas for this?

Hi,

It appears to me there is no code on Line 446 of the C Source file. It's a commented line. The breakpoint needs to be put on Line 447, I think. Try double-clicking on the sidebar where it's highlighted orange in your screenshot. CCS will place a breakpoint at the nearest point that it will allow.

Hope it works for you. Good luck.

Hi,

Oh. I am sorry. But I tried again and moved the breakpoint to line 447 and I still get the same warning.

Hmm, I don't see it being set in the code window.

Please try the other method I suggested:

Double-click in the region I've highlighted in Red. It should set the breakpoint. Here's what it looks like in my code:

Hi,

I have tried it at the various points in the ipout.c file. It seems like it doesn't work on any of the lines, no matter they are comments or actual line of codes. It throws the warning that no code is associated, but definitely this is part of my project as it routes the packet.

Hi Vishav,

My only other thought is stepping through your code using F6 and ensuring the functions are being called from "ipout.c". It doesn't make sense to me if the Source file is part of the project. Any code being used by the project should be able to be halted by a breakpoint.

Can you provide a screenshot your Project Explorer window as well from the Debug or Edit view so we can view your project contents?

I think we will need TI's input at this point, as unfortunately I'm out of ideas. Sorry I couldn't figure it out for you.

Best of luck.
Alec

Vishav,

"I want to add a breakpoint in fdt/ipout.c at function LLITxIpPacket function."

LLITxIpPacket() function body is in below file:

ndk_3_40_01_01/packages/ti/ndk/stack/lli/lliout.c

And LLITxIpPacket() function is invoked in below two files:

ndk_3_40_01_01/packages/ti/ndk/stack/lli/lliin.c
ndk_3_40_01_01/packages/ti/ndk/stack/ip/ipout.c

I can not find fdt/ipout.c file in AM335x RTOS SDK. Can you check again?

Regards,
Pavel
