TMS320F28035: ADC in TMS320F28035

Hi,

Due to Thanksgiving Holiday, the subject matter expert is out of office. We will get back to you next week.

Thanks & Regards,

We have implemented it by referring ADC-SOC example from ControlSuite SDK using CCS IDE

Would it be possible for you to try the ADC soc example from C2000Ware SDK instead of the ControlSUITE one. C2000Ware is our latest SDK.

Please let me know if you are experiencing the same issue with the C2000Ware example.

Hello Marlyn,

We have tried the ADC-soc example from ControlSuite and C2000Ware SDK, we are able to debug it. But, when the ADC logic from same code is mapped into our application code, we are facing the issue described above. Do we have any alternative. Kindly check and reply.

Thanks & Regards,

Nikhila,

  Marlyn is out-of-the office (and so are many other subject-matter-experts). She will be back in the first week of January, at which time you can expect a response. Thank you for your understanding and patience.

To be clear, the issues you face with not getting any call stacks only happen when you insert the code into your own application code and not with the example provided in c2000Ware?

Hello Marlyn,

Yes. We face this issue only when we insert the code into your own application code.

Hi Nikhila,

Thank you for the clarification. Let me send this question to someone else on our team who would be able to best assist you.

The same application didn't have this problem before you integrated the ADC code? You're using the same cmd file, same ccxml file, same debugger settings, yes?

If you halt the application by hitting the suspend button or by placing breakpoints (either using CCS or putting ESTOP0 instructions in code) does it work? Does the code appear to be running normally aside from the fact that it doesn't halt at main() when first loaded or is it getting stuck somewhere?

Hi Whitney,

1. The same application didn't have this problem before you integrated the ADC code? You're using the same cmd file, same ccxml file, same debugger settings, yes?

Yes, we didn't have this problem before integrating ADC. We are using the same cmd, ccxml files with same debugger settings.

2. If you halt the application by hitting the suspend button or by placing breakpoints (either using CCS or putting ESTOP0 instructions in code) does it work? Does the code appear to be running normally aside from the fact that it doesn't halt at main() when first loaded or is it getting stuck somewhere?

Yes, the application halts if we hit the Suspend button. While executing, it gets struck in ITRAP.

Is it at your application's ITRAP handler or the boot ROM one or some other code?

Can you try putting a breakpoint at c_int00 and/or code_start (may need to do it in the Disassembly window)? Then reset the device in the debugger (but don't hit the restart button) and run and see if it hits the breakpoint?
