The following response should be shown on the screen.

root@localhost:/tmp/example/hello_world# make

/usr/local/arm-linux/bin/arm-linux-gcc -I/usr/local/arm-linux/include

-I/usr/local/arm-linux/include/RTU -o hello_world hello_world.o

-L/usr/local/arm-linux/lib -lpthread -lmxml -L/usr/local/arm-linux/lib/RTU

-lmoxa_rtu -lrtu_common -ltag -Wl,-rpath,/lib/RTU/ -Wl,--allow-shlib-undefined

The hello_world-release and hello_world-debug executable files are described as below:

• hello_world-release: an ARM platform executable file (created specifically to run on the Moxa RTU

Controllers)

• hello_world-debug: an ARM platform GDB debug server executable file

NOTE

Since Moxa’s tool

chain places a specially designed makefile in the /tmp/example/hello_world directory,

sure to type the

#make command from within that directory. If users type the #make command from any

other directory, the host L

inux PC may use other system compilers (e.g., cc or gcc) and result in errors.

Upload & Run the Program

Follow the steps below to upload and run the hello_world.c program.

Step 1: Use the telnet command to access the console of the RTU controller.

root@localhost:~# telnet 192.168.127.254

Step 2: Enter root for both the account and password.

Step 3: Before uploading the compiled program to the RTU controller, check the free space of the flash memory

on the RTU controller. If the flash memory is full, you cannot save data to the flash ROM. Use the following

command to calculate the amount of available flash memory.

root@Moxa:~# df –h

NOTE

If there is

not enough available space for user’s program, users must delete some existing files.

Step 4: Use the following commands to connect the FTP server of the RTU controller.

root@localhost:/tmp/example/hello_world# ftp 192.168.127.254

Step 5: Enter root for both the account and password.

Step 6: Use the following commands to upload hello_world-release to the RTU controller by FTP in Binary

mode

ftp> cd /home

ftp> put hello_world

Step 7: Use the following commands to run the hello_world program on the RTU controller.

root@Moxa:/home~# chmod +x hello_world

root@Moxa:/home~# ./hello_world
