  • Page 57 Commands Execute Usage:GO <addr> The GO command executes target code starting at address addr. The value for addr may be an absolute address specified as a hexadecimal value, or a symbol name. If no argument is provided, the GO command begins executing instructions at the current program counter.
  • Page 58 Control is only regained when the target code encounters a breakpoint, illegal instruction, or other exception which causes control to be handed back to dBUG. Examples: To execute code up to the C function bench(), the command is: gt _bench 3-20 M5271EVB User’s Manual...
  • Page 59 Commands Internal Register Display Usage:IRD <module.register> This command displays the internal registers of different modules inside the MCF5271. In the command line, module refers to the module name where the register is located and register refers to the specific register to display. The registers are organized according to the module to which they belong.
  • Page 60 The data parameter specifies the new value to be written into the register. Example: To modify the TMR register of the first Timer module to the value 0x0021, the command is: timer1.tmr 0021 3-22 M5271EVB User’s Manual...
  • Page 61 Commands HELP Help Usage:HELP <command> The HELP command displays a brief syntax of the commands available within dBUG. In addition, the address of where user code may start is given. If command is provided, then a brief listing of the syntax of the specified command is displayed. Examples: To obtain a listing of all the commands available within dBUG, the command is: help...

  • Page 63 Commands Loop Write Usage:LW<width> addr data The LW command continually writes data to addr. The optional width specifies the size of the access to memory. The default access size is a word. Examples: To continually write the longword data 0x12345678 to address 0x20000, the command is: lw.l 20000 12345678 Note that the following command writes 0x78 into memory:...
  • Page 64 To display a range of bytes from 0x00040000 to 0x00050000, the command is: md.b 40000 50000 To display a range of 32-bit values starting at 0x00040000 and ending at 0x00050000: md.l 40000 50000 3-26 M5271EVB User’s Manual...
  • Page 65 Commands Memory Modify Usage:MM<width> addr <data> The MM command modifies memory at the address addr. The value for addr may be an absolute address specified as a hexadecimal value, or a symbol name. Width specifies the size of the data that is modified. If no <width> is specified, the default of word sized data is used.
  • Page 66 Usage:mmap This command displays the memory map information for the M5271EVB evaluation board. The information displayed includes the type of memory, the start and end address of the memory, and the port size of the memory. The display also includes information on how the Chip-selects are used on the board and which regions of memory are reserved for dBUG use (protected).
  • Page 67 Commands Register Display Usage:RD <reg> The RD command displays the register set of the target. If no argument for reg is provided, then all registers are displayed. Otherwise, the value for reg is displayed. dBUG preserves the registers by storing a copy of the register set in a buffer. The RD command displays register values from the register buffer.
  • Page 68 The actual value will not be written to the register until target code is executed. Examples: To change register D0 on MC68000 and ColdFire to contain the value 0x1234, the command is: D0 1234 3-30 M5271EVB User’s Manual...
  • Page 69 Commands RESET Reset the Board and dBUG Usage:RESET The RESET command resets the board and dBUG to their initial power-on states. The RESET command executes the same sequence of code that occurs at power-on. If the RESET command fails to reset the board adequately, cycle the power or press the reset button.
  • Page 70 The SD command displays a back trace of stack frames. This command is useful after some user code has executed that creates stack frames (i.e. nested function calls). After control is returned to dBUG, the SD command will decode the stack frames and display a trace of the function calls. 3-32 M5271EVB User’s Manual...
  • Page 71 Commands Set Configurations Usage:SET <option value> The SET command allows the setting of user-configurable options within dBUG. With no arguments, SET displays the options and values available. The SHOW command displays the settings in the appropriate format.
