Part Number: SAFETI_DIAG_LIB
Hi All,
I am using TMS570LC43 MCU with safeTI Diagnostic Library and intigrate with RTOS.
I am facing a problem that the HIGHHANDLER is not getting memory allocation. And the value of "uint32 size=(uint32)&ulHighHandlerSize;" is always 0. and system goes into SWRST mode.
I saw in map file it is not allocate any memory to ".sl_stflash_SRAM".
I am sharing linker code below.

Can you please tell me why i am not getting memory allocation for HIGH_HANDLER or ".sl_stflash_SRAM"?
Due to this the below section of code is not execute and system goes into reset mode.
uint32 i; /*TODO*/
uint32 size=(uint32)&ulHighHandlerSize; /*TODO*/
for(i=0;i<size;i++) /*TODO*/
{
((char *)&ulHighHandlerStartAddr)[i] =((char *)&ulHighHandlerLoadStart)[i]; /*TODO*/
}
We also having pragma in sl_selftest.c
#ifdef __TI_COMPILER_VERSION__
#pragma CODE_SECTION (SL_SelfTest_Flash, ".sl_stflash_SRAM")
#endif
