TMS570LS31x: Program does not reach main but instead jumps to reset shortly after entry point

Other Parts Discussed in Thread: HALCOGEN

Hi Ki,

Thank you for excluding the connection as a problem.

Following your post, disabled the auto run, reached the entry point, from here stepping “F5” or “F6” is jumping to reset. Can’t step through until (2).

Now, the next step would be to disable the WDT.

Possible way:

http://www.ti.com/lit/ug/slau132t/slau132t.pdf

page 78, option: --cinit_hold_wdt

Added –cinit_hold_wdt=on flag to the linker:

rror #10427-D: The symbol "WDTCTL_SYM" is unresolved. This symbol is required when --cinit_hold_wdt=on is used. The issue is mostly likely thatyour device does not support holding the watchdog timer when performing C auto initialization.

Then found the symbol:

the preprocessor __ARM_ARCH macro, on compiler:

www.ti.com/.../spnu151t.pdf

on page 40: -mv7r4, should have been set.

Do you have a better alternative?

Kind regards,

Alexander

Alexander,

As mentioned earlier, this is getting a bit beyond my area of expertise. I am going to split your last post to a new thread and move it to the Hercules forum. The experts there can help you best.

Since the original (tools specific) questions have been answered. I will close the original thread. Further responses from the device experts will continue in this "new" thread.

Thanks

Hello Alexander,

Would it be possible for you to share with us the project with failure signature so we can reproduce the problem?

Thanks.

best regards,

David Zhou

Hello Alexander,

Please use the HALCoGen generated _C_int00() in sys_startup.c as the entry point.

http://www.ti.com/tool/HALCOGEN

Your project doesn't include the exception vector table.

Hi QJ,

Thank you for your reply.
May I ask you, how do I generate the generated _C_int00() in sys_startup.c from HALCOGEN, and not more, so that I am able to debug the previous project?

Hello,

The HALCoGen generated _C_int00() includes the device initialization, self-tests based on your selection on HALCoGen. It calls __TI_auto_init() at the end to initialize the copy table.

Hi QJ,

Thank you for your reply.
What’s the minimum setting in Halcogen to get the very minimum startup functions and to be able to debug the hello world project.

Hello,

For testing _c_int00(), you can disable all the peripherals under "Driver Enable" tab, and uncheck the self-test of the peripherals you are not going to use.

The simplest _C_int00() only contains:

1. Initialization of MCU registers

2. Initialization the stack pointers

3. Enable CPU Event Export

4. check for power-on reset condition

5. Initialize System - Clock, Flash settings

6. Initialization of CPU RAM.

7. Initialization of ESM, VIM modules

8. Initialize copy table by calling __TI_auto_init();

9. Jump to main()

Hi QJ.

Sorry for the late feedback.
Thank you for your reply. I'll test the code generation with the disabled drivers.
