Freescale Semiconductor
Examples:
To set the byte at location 0x00010000 to be 0xFF, the command is:
mm.b 10000 FF
To interactively modify memory beginning at 0x00010000, the command is:
mm 10000

MMAP (Memory Map Display)
Usage: mmap
This command displays the memory map information for the M5251C3 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.
Here is an example of the output from this command:
Type Start End Port Size
---------------------------------------------------
SDRAM 0x00000000 0x003FFFFF 32-bit
Vector Table 0x00000000 0x000003FF 32-bit
USER SPACE 0x00020000 0x003FFFFF 32-bit
MBAR 0x10000000 0x100003FF 32-bit
Internal SRAM 0x20000000 0x20000FFF 32-bit
External SRAM 0x30000000 0x3007FFFF 32-bit
Flash
0xFFE00000 0xFFFFFFFF 16-bit
Chip Selects

RD (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.
Examples:
To display all the registers and their values, the command is:
rd
To display only the program counter:
rd pc
