Here's another good one. Again, works fine on simulator/debugger, but not on the target hardware. If I do this: BYTE process_Help(char *cmdBuffer) reentrant { cmdBuffer[0] = '\0'; printf( "Help Message"); return TRUE; } everything works fine. But if I do this: BYTE process_Help(char *cmdBuffer) reentrant { char *strHelp = "Help Message"; cmdBuffer[0] = '\0'; printf(strHelp); return TRUE; } it works fine on the simulator/debugger, but nothing is displayed when executed on the target hardware. Any/All help welcome and appreciated. Thanks, Chris Beattie
