Most likely you are compiling with optimization enabled.  This can cause the
c code to execute in a different sequence than you wrote.

Subject: debug irregularly!



hi,there
          when i debug(debugger=BDI2000;cpu=8xx) U-boot in flash, it
jumps irregularly as it running into "C" code, which always trouble me
-<. How can i get a "normal" debug sequence? is it need to add some
debug parameter into config.mk?
          thanks for any help !
