TMS320F28388D: Memory violation at 0x63FF

Tool/software:

Hi,

I'm using the following linker file and I have a problem with it, the problem is that I get memory violation at 0x63FF address, I don't touch this memory in my code but I get this violation, 
I want to know what is the reason ? Because sometimes my code works unpredictable and I guess that could be a reason for that.

.cmd file:

#ifdef CLA_BLOCK_INCLUDED
// Define a size for the CLA scratchpad area that will be used
// by the CLA compiler for local symbols and temps
// Also force references to the special symbols that mark the
// scratchpad are.
CLA_SCRATCHPAD_SIZE = 0x100;
--undef_sym=__cla_scratchpad_end
--undef_sym=__cla_scratchpad_start
#endif //CLA_BLOCK_INCLUDED

    Hi,

    Apologies for the late reply. Can you please share the .map file for further analysis?

    i don't see this memory mapped to any memory location in the linker cmd file. 

    Can you try using any of the existing linker cmd files present in our SDK and check if you are still getting similar error?

    Location - C2000Ware_5_04_00_00\device_support\f2838x\common\cmd

    i think in you program you are trying perform a read/write operation to this location. Can you try to debug your code step by step and check which instruction is causing this issue?

    Thanks

    Aswin
