NOTE Since Moxa’s tool chain places a specially designed Makefile in the directory
/tmp/example/hello, be sure to type the #make command from within that directory. This
special Makefile uses the mxscale-gcc compiler to compile the hello.c source code for the Xscale
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 Makefile example.
Uploading and Running the “Hello” Program
Use the following commands to upload hello-release to the W311/321/341 by 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 W311/321/341, type:
# chmod +x hello-release
# ./hello-release
The word Hello will be printed on the screen.
root@Moxa:~# ./hello-release
