UC-8410A Series Linux Software Programmer’s Guide

6-6

After compiling the program, issue the following command to execute the program.

moxa@Moxa:~$ ./hello-release

Hello World

Compiling Hello.c with Cross Compilation

Follow these steps for cross compilation.

1. Connect the UC-8410A-LX series to a Linux PC.

2. Install Tool Chain (GNU Cross Compiler & glibc).

3. Set the cross compiler and glibc environment variables.

4. Code and compile the program.

5. Download the program to the UC-8410A series via SFTP, NFS, SCP, or RSYNC.

6. Debug the program

 If bugs are found, return to Step 4.

 If no bugs are found, continue with Step 7

7. Back up the user directory (distribute the program to additional UC-8410A series units if needed).

The CD provided with the UC-8410A contains several example programs. Here we use Hello.c as an example

to show you how to compile and run your applications. Type the following commands from your PC to copy the

files used for this example from the CD to your computer’s hard drive:

# cd /tmp/

# mkdir example

# cp –r /mnt/cdrom/example/* /tmp/example

To compile the program, go to the Hello subdirectory and issue the following commands:

#cd example/hello

#make

You should receive the following response:

[root@localhost hello]# make

arm-linux-gnueabihf-gcc -o hello-release hello.c

arm-linux-gnueabihf-strip -s hello-release

hello-release—an ARM platform execution file (created specifically to run on the UC-8410A series)

Uploading and Running the “Hello” Program

The program can be uploaded via SFTP, NFS, SCP, or RSYNC.

Use the following command to upload hello-release to the UC-8410A series via SFTP.

From the PC, type:

#ftp 192.168.3.127

Use the “put” command to initiate the file transfer:

sftp> put hello-release

Uploading hello-release to /home/moxa/hello-release

hello-release

From the UC-8410A-LX, type:

# chmod +x hello-release

# ./hello-release

The word Hello will be printed on the screen.
