Problems when linking SafeTi lib

Other Parts Discussed in Thread: HALCOGEN, TMS570LS3137

Hi I have been struggeling for a while now to get my current project for TMS570LS3137 to work with the SafeTI library. The project runs freeRTOS generated with HalCoGen.

I have downloaded and compiled the library for my MCU.

I have added include paths for the header files (.../safety_library/include and .../hal/include) furthermore I have added the SafeTILib_TMS570LS31_BE.lib to the linker.

I have included sl_api.h in my main file and when I try to run e.g:

SL_Init_R4Registers();

I get the following errors:

unresolved symbol StackModeABT, first referenced in SafeTILib_TMS570LS31_BE.lib<sl_asm_api.obj>
unresolved symbol StackModeFIQ, first referenced in SafeTILib_TMS570LS31_BE.lib<sl_asm_api.obj>
unresolved symbol StackModeIRQ, first referenced in SafeTILib_TMS570LS31_BE.lib<sl_asm_api.obj>
unresolved symbol StackModeSVC, first referenced in SafeTILib_TMS570LS31_BE.lib<sl_asm_api.obj>
unresolved symbol StackModeSYS, first referenced in SafeTILib_TMS570LS31_BE.lib<sl_asm_api.obj>
unresolved symbol StackModeUND, first referenced in SafeTILib_TMS570LS31_BE.lib<sl_asm_api.obj>

What can be the problem?

EDIT: SL_Set_nERROR() works fine though.

Hello,

sorry for a late response.

please see the documentation included with the Diagnostic Library for this function:

"void SL_Init_StackPointers ( void )

Initializes CPU's stack pointer for SVC, FIQ, IRQ, ABT, UND & SYS modes.

Description:
This function initializes the stack pointers for the privilege modes of the CPU. Following
variables are used as stack pointers and hence must be defined by the application. StackModeSVC,
StackModeFIQ, StackModeIRQ, StackModeABT, StackModeUND, StackModeSYS. Function uses the
macros Stack Size for various ARM modes from sl_config.h file."

Please check the demo application included in the SafeTI Diagnostic Library release version 1.1.0 for implementation hints.

Regards,

Girish Gajwani
