TMS320F28379D: After adding a function in main(), project debug issue: C28xx_CPU2: Trouble Removing Breakpoint with the Action "Finish Auto Run" at 0x1bd27: (Error -1066 @ 0x1BD27)

Hi Julia,

Most of engineers are out of office due to US holiday, so responses will be delayed.

In the function HILTestAsynchronousMotor_initialize() , what is the address HILTestAsynchronousMotor_DW, HILTestAsynchronousMotor_U, HILTestAsynchronousMotor_Y ?

Regards, Santosh

Hi Santosh,

Thanks for your reply! The struct variables are not addressed manually, they are global variables and allocated by compiler.

Customer did more try here. When customer only add some part of code into the project, the CCS could jump to main after load. But if customer add more code into project, the CCS should no symbols loaded. They cannot add whole functions and only some part, If add one more line, the CCS cannot go main.

So the question in my view is how to add large code into the demo project? Customer run this project in RAM and cmd file is:

// The user must define CLA_C in the project linker settings if using the
// CLA C compiler
// Project Properties -> C2000 Linker -> Advanced Options -> Command File
// Preprocessing -> --define
#ifdef CLA_C
// Define a size for the CLA scratchpad area that will be used
// by the CLA compiler for local symbols and temps
// Also force references to the special symbols that mark the
// scratchpad are.
CLA_SCRATCHPAD_SIZE = 0x100;
--undef_sym=__cla_scratchpad_end
--undef_sym=__cla_scratchpad_start
#endif //CLA_C

Julia,

When the customer added the code, does it compile successfully? Does compiler/linker reports any error?

Please ask the customer to review the mapfile.

If they can send the project when it breaks, we can review it.

Hi Santosh,

 Yes, when customer click "build" it will be passed, no error is reported.

Customer's map file is as follows:

https://tidrive.itg.ti.com/a/autCrvDrQqR460Kx/1bec57c6-c4bc-4408-af49-4a1c12ee4b4d?l

I will send the customer's project to you offline, thank you!

Julia

Julia,

Looks like it may be stack overflow.

Please try to increase the stack and then check it again.

Regards, Santosh

Hi Santosh,

Thanks for your reply! Could you provide more information and cues about the “stack overflow”? And how to set more space for stack in the C2000 project configuration?

Thank you very much.

Best,

Julia
