Bootloader
1.1.4.2
Host Terminal Program Set-up
A host terminal program is used to communicate with Bootloader. The terminal must be
configured to the following mode:
The following description assumes that Microsoft Windows HyperTerminal program is used. To
configure Microsoft HyperTerminal to communicate with Bootloader, the PC user should start
HyperTerminal and create a new connection. Select the COM port connected to the EVM board
and set:
The HyperTerminal can now display Bootloader messages.
1.1.5
Execute
To execute the Serial Bootloader application after loading it into Flash, set jumpers as described
in
Section 1.1.2.1
and push the RESET button.
If the terminal program is properly set up and the EVM and the Host PC are properly connected,
the terminal program will display a Bootloader start-up message:
"(c) 2000-2001 Motorola Inc. S-Record loader. Version 1.1"
To load the S-Record file, select the Transfer/Send text file from the HyperTerminal menu and
select a file. When the S-Record file is loaded and the application is started, the terminal windows
displays a message similar to this:
"(c) 2000-2001 Motorola Inc. S-Record loader. Version 1.1
Loaded 0x044d Program and 0x000a Data words.
Application started."
The download rate is about 7660 bytes of S-Record file per second loaded from the terminal or
about 1740 words of program or data memory stored into Flash per second.
If an error is detected while loading the S-Record file, the Bootloader displays the error message
and resets the processor. For example, if an S-record file contains a character that is not permitted
for S-Records, the following message is displayed:
"(c) 2000-2001 Motorola Inc. S-Record loader. Version 1.1
Error # 0002
Resetting the processor."
