| md <address>[<data_size>] [<length>] |
| |
| Description |
| ----------- |
| |
| The md command is used to dump the contents of memory. It uses a standard |
| format that includes the address, hex data and ASCII display. It supports |
| various data sizes and uses the endianness of the target. |
| |
| The specified data_size and length become the defaults for future memory |
| commands commands. |
| |
| address |
| start address to display |
| |
| data_size |
| size of each value to display (defaults to .l): |
| |
| ========= =================== |
| data_size Output size |
| ========= =================== |
| .b byte |
| .w word (16 bits) |
| .l long (32 bits) |
| .q quadword (64 bits) |
| ========= =================== |
| |
| length |
| number of values to dump. Defaults to 40 (0d64). Note that this is not |
| the same as the number of bytes, unless .b is used. |

| The empty commands cause a 'repeat', so that md shows the next available data |
| in the same format as before. |
