CC1310: Hwi_excHandler source cause Issue

Rodrigo Ladeira

Part Number: CC1310

Hi!!!!!

I am developing with CC1310F128, SimpleLink 4.10.1.01 SDK.

I have debug a Hwi exception following the documentation, but I have a doubt what is possible causing this exception (I could not find this functions)

Bellow the ROV screen when the exception occurs

CFSR Register

Thanks in advance!!!

The Program Counter when the exception has occured : 0x1001C2D4

The link register is: 0x1001A833

The problems you are seeing is most likely due to memory corruption and it is kind of hard to debug. I guess you have taken a look at this documentation:

https://dev.ti.com/tirex/content/simplelink_cc13x0_sdk_3_20_00_23/docs/proprietary-rf/proprietary-rf-users-guide/proprietary-rf-guide/debugging-index.html#exception-cause

Since in your case the CFSR:BFARVALID flag is asserted when the exception occurs (typical for PRECISERR), the BFAR register in CPU_SCS can be read out to find which memory address caused the exception.

Hi Siri,

I tried reaaly hard to find what is causing the hardfault, but I could not understand what is happen because the PC is pointer to a RTOS intrusion 0x1001c2d4. I really blind how can I debug this hardfault

          ti_sysbios_knl_Queue_next__E:
1001c2d4:   6800                ldr        r0, [r0]
1001c2d6:   4770                bx         r14

- Have you checked that all task stacks are large enough?

- Do you get this error the first time you run through the code? If so, have you verified that you don't have any NULL pointers.

Hi.

- Have you checked that all task stacks are large enough?

R: Yes! I have allocated 2048 bytes for a simple task and It is possible to see that I am using much less then the Steackpeak

- Do you get this error the first time you run through the code? If so, have you verified that you don't have any NULL pointers.

The hardfault happen aleatory, just after a Pin interrupt occurs, but not in the execution of the Pin interruption function handler.

Bellow the ROV screen just when the exception occurred.

What undefined Hwi:29 could be?

Do you have a minimum example that show this error?

Hi,

I resolved the issue, it was my mistake. One array was point out of the declared size.

Thanks everybody for the help
