Moxa DA-662A-I-16-LX [16/63] Developing your first application

DA-662A Series Software Getting Started

2-8

You should receive the following response:

[root@localhost hello]# make PREFIX=arm-none-linux-gnueabi-

arm-none-linux-gnueabi-gcc –o hello-release hello.c

arm-none-linux-gnueabi-strip –s hello-release

arm-none-linux-gnueabi-gcc –ggdb -o hello-debug hello.c

[root@localhost hello]# _

Next, execute make to generate hello-release and hello-debug, which are described below:

hello-release—an execution file (created specifically to run on the DA-662A series)

hello-debug—an GDB debug server execution file (see Chapter 5 for details about the GDB debug tool).

NOTE

Be sure to type the #make command from within the /tmp/example/hello directory, since DA-662A‘s tool

chain puts a specially designed Makefile in that directory. This special Makefile uses the

arm-none-linux-gnueabi-gcc compiler to compile the hello.c source code for the Moxa Macro environment. If

you type the #make command from within any other directory, Linux will use the x86 compiler (for example,

cc or gcc).

Refer to Chapter 5 to see a Make file example.

Uploading and Running the “Hello” Program

Use the following command to upload hello-release to the DA-662A series via FTP.

1. From the PC, type:

#ftp 192.168.3.127

2. Use the bin command to set the transfer mode to Binary mode, and then use the put command to initiate

the file transfer:

ftp> bin

ftp> put hello-release

3. From the DA-662A series, type:

# chmod +x hello-release

# ./hello-release

The word Hello will be printed on the screen.

root@Moxa:~# ./hello-release

Hello

Developing Your First Application

We use the tcps2 example to illustrate how to build an application. The procedure outlined in the following

subsections will show you how to build a TCP server program with serial port communication that runs on the

DA-662A series.
