Commands
DN
Usage:
The DN command downloads code from the network. The DN command handle files which are
either S-record, COFF, ELF or Image formats. The DN command uses Trivial File Transfer
Protocol (TFTP) to transfer files from a network host.
In general, the type of file to be downloaded and the name of the file must be specified to the DN
command. The -c option indicates a COFF download, the -e option indicates an ELF download,
the -i option indicates an Image download, and the -s indicates an S-record download. The -o
option works only in conjunction with the -s option to indicate an optional offset for S-record
download. The filename is passed directly to the TFTP server and therefore must be a valid
filename on the server.
If neither of the -c, -e, -i, -s or filename options are specified, then a default filename and filetype
will be used. Default filename and filetype parameters are manipulated using the SET and SHOW
commands.
The DN command checks the destination download address for validity. If the destination is an
address outside the defined user space, then an error message is displayed and downloading
aborted.
For ELF and COFF files which contain symbolic debug information, the symbol tables are
extracted from the file during download and used by dBUG. Only global symbols are kept in
dBUG. The dBUG symbol table is not cleared prior to downloading, so it is the user’s responsibility
to clear the symbol table as necessary prior to downloading.
If an entry point address is specified in the S-record, COFF or ELF file, the program counter is set
accordingly.
Examples:
To download an S-record file with the name “srec.out”, the command is:
To download a COFF file with the name “coff.out”, the command is:
To download a file using the default filetype with the name “bench.out”, the command is:
To download a file using the default filename and filetype, the command is:
