Commands
BM Block Move
Usage:BM begin end dest
The BM command moves a contiguous block of memory starting at address begin and
stopping at address end to the new address dest. The BM command copies memory as a
series of bytes, and does not alter the original block.
The values for addresses begin, end, and dest may be absolute addresses specified as
hexadecimal values, or symbol names. If the destination address overlaps the block defined
by begin and end, an error message is produced and the command exits.
Examples:
To copy a block of memory starting at 0x00040000 and ending at 0x00080000 to the
location 0x00200000, the command is:
bm 40000 80000 200000
To copy the target code’s data section (defined by the symbols data_start and data_end) to
0x00200000, the command is:
bm data_start data_end 200000
NOTE
Refer to “upuser” command for copying code/data into Flash
memory.
