Use this command to download configuration and application data over the serial port into RAM or FLASH. The 68K Monitor accepts a transfer of ZMODEM binary data to the D25 initiated either by the D25 user or by the sending terminal.
When the transfer is complete, the DOWNLOAD command returns control to 68K Monitor’s command line.
Application code download only works when:
•executing from the BootROM, and
•the monitor has erased the FLASH region.
While the command downloads the file, it recognizes the ZLIB format of the compressed data and uncompresses it.

|
| Considerations |
|
|
| ||
|
|
| • If there are parameters on the command line, the monitor |
| |||
|
|
| assumes that the D25 initiated the download, and allows 20 |
| |||
|
|
| seconds for the user to activate the software that will send |
| |||
|
|
| data to the D25. |
|
|
| |
|
|
| • If there are no parameters, the monitor assumes that the |
| |||
|
|
| sending software initiated the download and it will not |
| |||
|
|
| provide a wait period. |
|
|
| |
|
|
| The command “rz” is the standard prefix used by the |
|
|
| |
|
|
| ZMODEM binary protocol to start a file transfer. A terminal |
| |||
|
|
| using this command can connect to the D25 Monitor and |
|
|
| |
|
|
| simply start sending ZMODEM data without any further user |
| |||
|
|
| input to the D25. |
