Hi TI-friends,

By checking the CCS_CRASH_DUMP_XXX, we could found the problem may be related to which file. Is there more info we can got??

And I want to know more detail about these registers as below

where I can find them ??

Ptr r0; /**< R0 Register value when exception occurred */
Ptr r1; /**< R1 Register value when exception occurred */
Ptr r2; /**< R2 Register value when exception occurred */
Ptr r3; /**< R3 Register value when exception occurred */
Ptr r4; /**< R4 Register value when exception occurred */
Ptr r5; /**< R5 Register value when exception occurred */
Ptr r6; /**< R6 Register value when exception occurred */
Ptr r7; /**< R7 Register value when exception occurred */
Ptr r8; /**< R8 Register value when exception occurred */
Ptr r9; /**< R9 Register value when exception occurred */
Ptr r10; /**< R10 Register value when exception occurred */
Ptr r11; /**< R11 Register value when exception occurred */
Ptr r12; /**< R12 Register value when exception occurred */
Ptr sp; /**< Stack pointer Register value when exception occurred */
Ptr lr; /**< LR Register value when exception occurred */
Ptr pc; /**< Program Counter value when exception occurred */
Ptr psr; /**< psr register value when exception occurred */
Ptr ICSR; /**< ICSR register value when exception occurred */
Ptr MMFSR; /**< MMFSR register value when exception occurred */
Ptr BFSR; /**< BFSR register value when exception occurred */
Ptr UFSR; /**< UFSR register value when exception occurred */
Ptr HFSR; /**< HFSR register value when exception occurred */
Ptr DFSR; /**< DFSR register value when exception occurred */
Ptr MMAR; /**< MMAR register value when exception occurred */
Ptr BFAR; /**< BFAR register value when exception occurred */
Ptr AFSR; /**< AFSR register value when exception occurred */

hi TI-friends,

dvr_rdk_bios6.aem3 : avsync_m3vpss.oem3 (.bss:taskStackSection)

captureLink_tsk.oem3 (.bss:taskStackSection)
systemLink_tsk_m3vpss.oem3 (.bss:taskStackSection) ==> here...
system_common.oem3 (.bss:taskStackSection)
system_ipc_msgq.oem3 (.bss:taskStackSection)

memory header points the above,

Q1. does that mean there's exception in the corresponding file and in bss section? what does ".bss:taskStackSection" mean??

and I check

#pragma DATA_SECTION(gSystemLink_tskStack, ".bss:taskStackSection")

UInt8 gSystemLink_tskStack[SYSTEM_TSK_STACK_SIZE];

And I found

status = Utils_tskCreate(&pObj->tsk,
SystemLink_tskMain,
SYSTEM_TSK_PRI,
gSystemLink_tskStack,
SYSTEM_TSK_STACK_SIZE, pObj, tskName);

Q2. But I'm not sure if it means the in enough stack size. Did you have any idea?

Refer http://processors.wiki.ti.com/index.php/Crash_Dump_Analysis for understanding the crash dump format and how to analyze.

Refer the cortexM3 TRM for understanding register description

Refer the cortexM3 TRM for understanding register description

- the description is in "Generic User Guide"(http://infocenter.arm.com/help/topic/com.arm.doc.dui0552a/DUI0552A_cortex_m3_dgug.pdf) instead of "Technical Reference Manual"(http://infocenter.arm.com/help/topic/com.arm.doc.ddi0337i/DDI0337I_cortexm3_r2p1_trm.pdf)... just share

hello super-badri,

by checking the document, there's description about the R0~R12 as below

General-purpose registers
R0-R12 are 32-bit general-purpose registers for data operations.

So I think the usage of these registers is decided by TI, right?? And I didn't find the explain in your provided TI's URL.

Could you help to explain or provide a document? Thanks

You can refer C compiler user guide www.ti.com/lit/ug/spnu151h/spnu151h.pdf and http://www.arm.com/products/DevTools/ABI.html to understand C compiler register usage convention. I am not sure what you will make from register values though.Why don't you attach the crash dump text file and the contents of dvr_rdk\build\dvr_rdk\bin\ti816x-evm as I previously mentioned.
