Motorola CMD11E1 manual Running your application, Hello.Lst

Page 6

If there are no errors in your source code, 2 output files will be created:

HELLO.S19

a Motorola S-Record file that can be programmed into memory

HELLO.LST

a common listing file which shows the relationship between source

 

and output

The listing file is especially helpful to look at when debugging your program. If your program has errors, they will be displayed and no output will be generated, otherwise the listing file will be displayed.

Running your application

After creating an S-Record file you can "upload" it to the development board for a test run. The provided example “HELLO.ASM” was created to run from RAM so you can use the Buffalo Monitor to test it without programming it into EEPROM.

If you haven’t done so already, verify that the CMD11E1 board is connected and operating properly by following the steps under “GETTING STARTED” until you see the buffalo prompt, then follow these steps to run your program:

1.Press and release the RESET button on the CMD11E1 board. You should see the Buffalo Monitor message. Hit the return key to get the monitor prompt.

2.Type LOAD T

This will prepare buffalo to receive a program.

3.Select Upload and when prompted for a file name select your assembled program file in s-

record format that was created in the previous section called:

HELLO.S19

Your program will be sent to the board thru the serial port.

 

4.When finished loading you will see the > prompt again. Type CALL 2400

This tells buffalo to execute the subroutine at address $2400, which is the start of our test program.

5.If everything is working properly you should see the message “Hello World” echoed back to your terminal screen then, since we return at then end of our program, a line containing the internal register status displayed by buffalo and the buffalo prompt.

6.If you do not get this message, try going thru this tutorial once more, then if still no go, see the TROUBLESHOOTING section in this manual

You can modify the hello program to display other strings or do anything you want. The procedures for assembling your code, uploading it to the board and executing it remain the same. Buffalo has many powerful features such as breakpoints, assembly/disassembly, memory dump and modify and program trace. Type HELP at the buffalo prompt for a listing of commands or consult the buffalo documentation file for more information.
