.. SPDX-License-Identifier: GPL-2.0+: md command ========== Synopis ------- :: md
[] [] 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.
