NAME

       memtool - display and modify memory

SYNOPSIS

       memtool md [-b|-w|-l|-q] [-x] [-s filename] region
       memtool mw [-b|-w|-l|-q] [-d filename] start data...

DESCRIPTION

       memtool  allows one to read and write regions of files. When applied to
       /dev/mem (which is the  default  file)  the  regions  represent  memory
       mapped registers.

       There  are currently two subcommands: mw to write to memory/a file; and
       md to read from memory/a file.

       Note that on some machines there are alignment restrictions that forbid
       for  example  to  read a word from an address that is not word aligned.
       memtool doesn't try to be smart here but simply tries what is requested
       by  the  caller.  This might result in all kind of errors which are not
       considered to be a bug of the tool,  but  either  the  machine  or  the
       caller.

OPTIONS

       -b     Use byte wise (8-bit) access

       -w     Use word wise (16-bit) access

       -l     Use long wise (32-bit) access

       -q     Use quad wise (64-bit) access

       -d filename
              Write to filename.

       -s filename
              Read from filename.

       -x     Swap bytes at output

REGIONS

       Memory regions can be specified in two different forms:

       start[+size]

       start-end

       start  specifies  the  byte  offset of the region's beginning, i.e. the
       first included address.  size specifies the size of the region in bytes
       and  defaults  to  0x100. Alternatively end specifies the offset of the
       last  included  address.   Offsets  can  be  specified  in  decimal  or
       hexadecimal  with a prefix 0x.  Additionally you can use suffixes G, M,
       and k, which multiply by 1024^3, 1024^2, and 1024 respectively.
