■Example 3
(gdb) x /16h _START_text
0xc00000 <_START_text>: 0x0004 0x00c0 0xc020 0x6c0f 0xa0f1 0xc000 0xc000 0x6c0f
0xc00010 <boot+12>:
When Length is specified, the specified amount of data is displayed.
When a code area is displayed, <label+offset> is displayed as the symbol, even for addresses without defined symbols.
■Example 4
(gdb) x /4w 0
0x0 <i>: 0x00001ae3 0x00000000 0x00000000 0x00000000
(gdb) x
0x10: 0x00000000
(gdb) x
0x14: 0x00000000
When the x command is executed once, you can dump and display a single unit of data (having the same size as that of the
previous address) from the address following the previous address by simply entering x.
■Example 5
(gdb) x /w &i
0x0 <i>: 0x00000010
(gdb) x /w i
0x10: 0x00000000
When specifying an address with a data symbol that references the assigned address, add & when you enter the command.
When only specifying a symbol, note that its data value is used as the address. In such case, & need not be added because labels
in program code indicate assigned addresses.
■Example 6
(gdb) x /10i boot
0x8004 <boot>:
0x8006 <boot+2>:
0x8008 <boot+4>:
0x800a <boot+6>:
0x800c <main>:
0x800e <main+2>:
0x8010 <main+4>:
0x8012 <main+6>:
0x8014 <main+8>:
0x8016 <main+10>:
The ten commands specified are displayed.
Notes
 Memory contents are displayed in little endian format.
 Even if the specified address is not a boundary address conforming to the data size, the x command starts displaying
memory contents from that address.
 If the specified address exceeds the 24-bit range, an error is assumed.
 An error does not occur even if a value of 2147483648 or greater is specified for Length. The value for Length is set to
2147483647.
