10.8 LO - Load S-Records to Memory
Format: LO [<host commands>]
LO <offset> [,<host commands>]
LO V [,<host commands>]
LO <offset>,V [,<host commands>]
LO E
The LO command allows to load S-Records from the console port into
memory and to verify the memory contents.
The optional parameter ’<host commands>’ allows to specify a list of
commands that will be sent to the host to initiate the data transfer, e.g.
’cat testfile’.
The first format of the command is a standard download. Data will be
loaded to the absolute addresses of the S-Records.
The second format contains parameter <offset> that specifies the value
that is added to the absolute addresses of the S-Records. This allows to
modify the storage address while the download.
The next two formats are the same as previously described, except that no
data will be loaded to memory, but a compare takes place between the
memory contents and the S-Record data. This allows to verify the data.
Command 'LO E' displays the number of errors that occurred during the
last download.
Example:
The following program originally located at address 10.0000

should be
loaded to 10.0200
16
via a ’tip’ connection.

00100006 NOP
00100008 SUBQ.L #1,D0
0010000a BNE.B $100006
