What's wrong with this "Stack Pointer Initialization"? - onemilimeter - Oct 16 8:50:27 2008

I have a TMS320C31 DSK.
I wrote a simple code as follows:

; *********************************************
          .start "CODE",0x809802
          .sect "CODE"
          .entry SAMPLE

SAMPLE    LDI 0x2027,SP
          LSH 10,SP
          OR  0x180,SP    ; Set SP as 0x809D80
; *********************************************
When I debugged using 'F8-SSTEP', I got the following error:
Host I/O recv error, (0xC4 OR'ed with IE?)

Can someone pls advise?

Thank you.
