TMS320F28377D: Stack overflow problem

Hi,

li xy said:

In my project, there is a Stack Overflow Detection function which is  "err = STKOV_initSystemStack((Uint32)&vStackStart, (Uint32)&vStackEnd, 8);". However, these days this function is always return 1 which means "software failed to gain control of the WP ".

If this your custom application or it is based on TI provided SDK?

2. Does C2000 have R13 register(SP) like ARM? if it has how to access it?

Please refer to C28x Assembly Instruction Set for the details on CPU core register SP.

1. It is my custom application

2. I roughly read the trm and find chapter 2.2.5 is just an intruduction of SP register. I wonder how to read the value of SP through asm or C code. I want the value of SP to detect whether the stack overflow.
