Using the Monitor/Debug Firmware
MD
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. Width modifies the size of the data that is displayed. If no <width> is specified,
the default of word sized data is used.
Memory display starts at the address begin. If no beginning address is provided, the MD command uses
the last address that was displayed. If no ending address is provided, then MD will display memory up to
an address that is 128 beyond the starting address.
This command first aligns the starting address for the data access size, and then increments the address
accordingly during the operation. Thus, for the duration of the operation, this command performs
properly-aligned memory accesses.
Examples:
To display memory at address 0x00400000, the command is:
To display memory in the data section (defined by the symbols data_start and data_end), the command is:
To display a range of bytes from 0x00040000 to 0x00050000, the command is:
To display a range of 32-bit values starting at 0x00040000 and ending at 0x00050000:
