Commands
MM
Usage:
The MM command modifies memory at the address addr. The value for addr may be an absolute
address specified as a hexadecimal value, or a symbol name. Width specifies the size of the data
that is modified. If no <width> is specified, the default of word sized data is used. The value for
data may be a symbol name, or a number converted according to the user-defined radix, normally
hexadecimal.
If a value for data is provided, then the MM command immediately sets the contents of addr to data.
If no value for data is provided, then the MM command enters into a loop. The loop obtains a value
for data, sets the contents of the current address to data, increments the address according to the
data size, and repeats. The loop terminates when an invalid entry for the data value is entered, i.e.,
a period.
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 set the byte at location 0xFFF1_0000 to be 0xFF, the command is:
To interactively modify memory beginning at 0xFFF1_0000, the command is:
