For remote debugging, you need to copy deploy the c-example binary to the target. This can be done in several ways:

• Using scp or sftp to copy the binary to the target;

• Using NFS share configured on the host and mounting this share from the target.

...

4.1. Using NFS

...

This application note shows demonstrates how to use NFS to configure share to copy the binary to on the host and mount this share from the target.

For In the example below, the Eclipse workspace directory, /srv/homes/eclipse-workspace/ is exported as NFS share. Let's

Perform the following step to modify the Linux project to auto-mount this the /srv/homes/eclipse-workspace/directory via NFS.

1. Add the following lines to etc/rc:

   Code Block
   % cd projects/rootfs % vi etc/rc ... sleep 2 mount -o nolock 192.168.0.103:/srv/homes/eclipse-workspace/ /mnt/nfs ...

2. Rebuild the project.

3. After loading the project to the target, the Eclipse workspace directory is mounted as /mnt/nfs:

   Code Block

   / # df Filesystem 1K-blocks Used Available Use% Mounted on 192.168.0.103:/srv/homes/eclipse-workspace/ 488645632 124968960 338781184 27% /mnt/nfs / # ls -la /mnt/nfs/c-example/Debug/ drwxrwxr-x 2 1005 1005 4096 Jun 11 2024 . drwxrwxr-x 4 1005 1005 4096 Jun 11 2024 .. -rw-rw-r-- 1 1005 1005 16 Jun 11 2024 app.d -rw-rw-r-- 1 1005 1005 52048 Jun 11 2024 app.o -rwxrwxr-x 1 1005 1005 41680 Jun 11 2024 c-example -rw-rw-r-- 1 1005 1005 1360 Jun 11 2024 makefile -rw-rw-r-- 1 1005 1005 402 Jun 11 2024 sources.mk -rw-rw-r-- 1 1005 1005 752 Jun 11 2024 subdir.mk / #
