  • Page 54: Operational Procedure

    Freescale Semiconductor, Inc. Operational Procedure Most commands can be recognized by using an abbreviated name. For instance, entering “h” is the same as entering “help”. Thus, it is not necessary to type the entire command name. The commands DI, GO, MD, STEP and TRACE are used repeatedly when debugging. dBUG recognizes this and allows for repeated execution of these commands with minimal typing.
  • Page 55 Freescale Semiconductor, Inc. Operational Procedure • Make sure the IP bit is set (switch 5 ON in MAP_SW). This will cause the board to boot out of external flash (where the dBUG code resides). • Turn power on to the board.

  • Page 77 Freescale Semiconductor, Inc. Commands Loop Read Usage: LR<width> addr The LR command continually reads the data at addr until a key is pressed. The optional <width> specifies the size of the data to be read. If no <width> is specified, the command defaults to reading word sized data.
  • Page 78 Freescale Semiconductor, Inc. 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 data 0x1234_5678 to address 0xFFF2_0000, the command is:...
  • Page 79 Freescale Semiconductor, Inc. Commands Memory Display Usage: MD<width> <begin> <end> The MD command displays a contiguous block of memory starting at address begin and stopping at address end. The values for addresses begin and end may be absolute addresses specified as hexadecimal values, or symbol names.
  • Page 80 Freescale Semiconductor, Inc. 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.

The display also includes information on how the Chip-selects are used on the board.
  • Page 82 Freescale Semiconductor, Inc. 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 83 Freescale Semiconductor, Inc. Commands Register Modify Usage: RM reg data The RM command modifies the contents of the register reg to data. The value for reg is the name of the register, and the value for data may be a symbol name, or it is converted according to the user-defined radix, normally hexadecimal.
  • Page 84 Freescale Semiconductor, Inc. Commands RESET Reset the Board and dBUG Usage: RESET The RESET command resets dBUG to it’s 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 system adequately, cycle the power or press the reset button.
  • Page 85 Freescale Semiconductor, Inc. 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. The standard set of options is listed below.

  • Page 87 Freescale Semiconductor, Inc. Commands STEP Step Over Usage: STEP The STEP command can be used to “step over” a subroutine call, rather than tracing every instruction in the subroutine. The ST command sets a temporary software breakpoint one instruction beyond the current program counter and then executes the target code. This command only works when executing code in SRAM.
  • Page 88 Freescale Semiconductor, Inc. Commands SYMBOL Symbol Name Management Usage: SYMBOL <symb> <-a symb value> <-r symb> <-c|l|s> The SYMBOL command adds or removes symbol names from the symbol table. If only a symbol name is provided to the SYMBOL command, then the symbol table is searched for a match on the symbol name and its information displayed.
  • Page 89 Freescale Semiconductor, Inc. Commands TRACE Trace Into Usage: TRACE <num> The TRACE command allows single-instruction execution. If num is provided, then num instructions are executed before control is handed back to dBUG. The value for num is a decimal number.
  • Page 90 Freescale Semiconductor, Inc. Commands VERSION Display dBUG Version Usage: VERSION The VERSION command displays the version information for dBUG. The dBUG version, build number and build date are all given. The version number is separated by a decimal, for example, “v 2b.1c.1a”.

    Freescale Semiconductor, Inc. System Call Functions 3.5 System Call Functions An additional utility within the dBUG firmware is a function called the System Call handler. This function can be called by the user program to utilize various routines within dBUG, to perform a special task, and to return control to dBUG.

System Call Functions /* assume r3 contains the character */ asm(“ addi r10, r0, 0x0000”); Selects the function asm(“ sc”); The character is returned in r3 3.5.3 IN_STAT This function (function code 0x0001) checks if an input character is present to receive. A value of zero is returned in r3 when no character is present.

System Call Functions C example: board_isr_remove (void *handler) asm( "addi r10,r0,0x0041"); asm( "sc"); 3.5.6 EXIT_TO_dBUG This function transfers the control back to the dBUG, by terminating the user code. The register context is preserved. C example (see “scif.s”file : anything in R10 besides 0x0000, 0x0001, 0x0020, 0x0030, 0x0031,...
