Intel IQ80960RM, RN 2.4 Creating and Downloading Executable Files

IQ80960RM/RN

Evaluation Board Manual 2-3

Getting Started

4. If you have MON960 installed in the flash ROM, press <ENTER> on a terminal connected to

the IQ80960RM/RN platform to bring up the MON960 prompt. MON960 automatically

adjusts its baud rate to match that of the terminal at start-up. At ba ud rates other than 9600, it

may be necessary to press <ENTER> several times .

2.4 Creating and Downloading Executable Files

To download code to the IQ80960RM/RN platform runn ing IxWorks, consult Wind River

documentation on the supplied TORNADO for I2O CD-ROM. To download code to the

IQ80960RM/RN platform, your compiler produces an ELF-format object file.

To download code to the IQ80960RM/RN platform runn ing CTOOLS, consult the CTOOLS

documentation for information regarding compiling, linking, and downloading applications.

During a download, MON960 checks the link address stored in the ELF file, and stores the file at

that location on the IQ80960RM/RN platform. If the executable file is linked to an invalid address

on the IQ80960RM/RN platform, MON960 aborts the download.

2.4.1 Sample Download and Execution Using GDB960

This example shows you how to use GBD960 to download and execute a file named myapp via

the serial port.

•Invoke GDB960. From a Windows 95/NT command prompt, issue the command:

gdb960 -r com2 myapp

This command establishes communication and downloads the file myapp.

•To execute the program, enter the command from the GDB960 command prompt:

(gdb960) run

More information on the GDB960 commands mentioned in this section can be found in the

GDB960 User’s Manu al .
