How to Mount a Remote NFS Server

Currently, the EM-1240-LX only supports NFS (Network File System) clients. Users can open NFS service on a Linux PC to enable the EM-1240-LX to push data to it. The EM-1240-LX can use NFS to mount a remote disk as a local disk for data or log purposes.

1.First, the NFS server must open an export directory and allow access to the IP address. Edit the file “/etc/exports” on your Linux PC, and then run the NFS daemon. The following example gives one possibility (refer to the NFS-HOWTO document at http://nfs.sourceforge.net/nfs-howto/server.html):

/home/usr 192.168.3.1 (rw,no_root_squash,no_all_squash)

2.The EM-1240-LX must run the “portmap” utility. This program is enabled by default in the “/etc/rc” file. Use the following command to mount the remote NFS server:

/>mount –t nfs <remote-ip>:<remote-export-directory> <local-directory>

Dynamic Driver Module Load/Unload

Besides supporting traditional static drivers, the EM-1240-LX also supports the dynamic driver module load / unload mechanism. It allows user to load a special driver into the kernel to enable hardware features for specific applications. To load / unload dynamic driver module, use the following commands.

Load module:

/>insmod <module-directory>/<module file name>

For example, to load the UART driver, type the following command:

/>insmod /lib/modules/2.6.9-MoXaRt/kernel/drivers/char/mxser.ko

Show module list:

/>lsmod

Unload module:

/>rmmod <module-name listed by lsmod command>

For example, to unload the UART driver, type the following command:

/>rmmod mxser

For the EM-1240-LX, the factory default is to load the UART driver “mxser.ko”. The additional driver module to control SD/MMC memory card is loaded for the EM-1240-LX. Please see the following information below to know the location and file name for these driver modules.

UART:

/lib/modules/2.6.9-MoXaRt/kernel/drivers/char/mxser.ko

SD/MMC:

/lib/modules/2.6.9-MoXaRt/kernel/drivers/mmc/mmc_core.ko /lib/modules/2.6.9-MoXaRt/kernel/drivers/mmc/mmc_block.ko /lib/modules/2.6.9-MoXaRt/kernel/drivers/mmc/moxasd.ko
