6.3.4.4. Using NFS Mount
To use NFS mount, have a NFS share prepared in your development PC and mount the directory
by using command mount -o nolock <dev-pc-ipaddress>:/nfsshare /mnt/nfs. After this, you
can access the share in directory /mnt/nfs.
6.3.5. Running an Application Transferred to Access Server
To run the application you just transferred to Access Server, you need access to the Access Server
console, either using terminal software connected to the Access Server management UART or
using the SSH connection (log in as user root and the root password, which is buffy by default).
Having established a connection to Access Server, change the directory to where your applica-
tion is located and change file permissions so that it can be executed, then run it.
Example 6-2. Running an Application
[root@wrap /] cd /tmp
[root@wrap /tmp] chmod 755 testapp
[root@wrap /tmp] ./testapp
6.3.6. Using Debugger (GDB/DDD)
You can use GNU debugger GDB and a graphical user interface, such as DDD, for debugging
applications in Access Server. This requires that you install gdbserver to Access Server. It can be
installed from a software package located in directory asdk/arch/arm/gpl/gdbserver/
You have to compile with debug options and without symbol stripping to make debugging
work. This can be done by overriding the default CFLAGS variable set in asdk/Rules.mak. You
can do this by adding line
CFLAGS = -Wall -Os -ggdb -I$(SDKBASE)/include
after line
include /home/user/asdk/Rules.mak
in Makefile
After you have compiled your application with these options and transferred your application
to Access Server, you can start debugging the application as follows:
1. Start gdbserver on Access Server
Usage:
gdbserver :<port> <your application>
Example: gdbserver :6789 ./hello
2. Start debugger on the host PC. (This example is for the DDD)
Example: ddd --debugger /usr/local/arm/3.4.5/bin/arm-linux-gdb hello
3. Create a connection to Access Server.
