Userland Applications Debugging Without PCS
After these steps, you should see the login prompt.

To debug userland applications using gdbserver, follow these steps:
6
1. gdb and gdbserver should be built. To build gdb, type: make gdb.
2. Upload image.bin to the target and run it.
3. romfs should contain the ELF file that you want to debug.
4. Run gdbserver on the target by typing gdbserver <board_ip>:<port> <path_to_application>
For example: gdbserver:3000 /bin/hello
Userland Applications Debugging Without PCS
To debug userland applications, it is best to choose:
2. Build the target root file system in a directory on the host. After clicking 'Next' you will see
rootfs creation process.
3. The next step allows you to remove debug information from the file system image. DO NOT
DO THIS if you want to debug applications (the check box should be checked). Click 'Next.’
4. Enter host info and click 'Next.’
5. Enter target network options.
6. The next step allows you to update the root file system with new network options BUT if the
nfs root was chosen during the first step, it is recommended to check 'Do not change the target
root file system' box. Click 'Next' button.
7. Check the box here if you want to automatically bring up the network interface on the target
board. Do not check this box if the nfs root was chosen during the first step. Click 'Next.’
8. This step configures the host tftp and nfs services. Check the 'Do not change host
configuration' box if your host is already configured or if you want to configure it manually.
Click 'Next.’
9. During this step, the target MAC address should be specified. The command line may remain
default. Click 'Next.’
10. Next step prepares ROMFS and JFFS file systems.
11. Follow the instructions on the page. Click 'Next.’
12. On this page, choose the host serial port device and terminal program.
13. During the next steps, the terminal program is run and commands are sent to dBUG. It loads
the colilo, which loads the kernel and executes it. Make sure the board is connected to the
network.
a. Application Development Deploy: this places the kernel into flash and allows use of
nfsroot.
b. Download, save and run colilo from Flash for the first deployment only. This places colilo
into flash and allows one to type 'go 0xE0000400' at the dBug prompt after board reset to
start the kernel.
c. Save dBUG vars in flash.
d. Configure colilo for autobooting of Linux after starting. Options should be checked. This
allows colilo to start the kernel automatically. Click 'Next.’
