Hi Guys, One of our customers is seeing a strange problem when debugging his VC33 code. He has a VC33 target board hooked up to Code Composer 4.10 with an XDS510PP Plus emulator. He has a small routine that is not returning properly. Looking at the code generated by the compiler, he can clearly see the instructions in the routine and the end of the routine - an unconditional branch to the address in AR1. If he places breakpoints on the last five or so lines of assembly code and effectively steps through to the end of the routine, then the value in AR1 is correct and it executes correctly. If he removes the breakpoints, or simply has one breakpoint 5 instructions before the end of the routine and another on the branch instruction then the routine branches to oblivion. The value of AR1 being correct 5 instructions before the end but junk by the time that the branch is reached. Has anyone else come across anything like this before? Best Regards, Kevin Howson Technical Manager Kane Computing Ltd |
