NFS server

Use the network file system (NFS) to simplify application debugging on the target. NFS allows your target to mount its root file system with read/write permissions from the host computer over Ethernet. NFS also allows you to access the file system from the target and from the host computer the same time.

The NFS server configuration details are beyond the scope of this User's Manual and are very specific to the various distributions. This manual only describes the modifications necessary on hosts running a Debian distribution. Please refer to your Linux distribution manual to setup a NFS server if you are using a different distribution.

When the NFS server package (Debian package nfs-kernel-server) is installed on Debian, there is a file "/etc/exports" that contains information on exported directories and its access rights. Add the following line to this file to provide read/write access for your target:

BOOTDIR IP_ADDRESS(rw,all_squash,async)

BOOTDIR needs to be replaced with the path to the NFS root directory which is exported to the target. The IP_ADDRESS needs to be replaced with the IP address of your target.

Please refer to the Linux man pages for detailed information about the /etc/exports file. The build process copies the NFS root to /export/nfsroot-<platformname>; e.g. to export the rootfs for cc9p9750, write the following to /etc/exports:

/exports/nfsroot-cc9p9750dev 192.168.42.10(rw,all_squash,async)

For simplicity’s sake you can export the whole /exports dir for a complete subnet, e.g.:

/exports 192.168.42.0/24(rw,all_squash,async)
