EM-1220 LX User’s Manual Configuring the EM-1220-LX

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. An additional

driver module for controlling the SD/MMC memory card is loaded for the EM-1240-LX. The

location and file name for these driver modules is given below.

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

Upgrading the Kernel

The EM-1220-LX kernel is em1220-1.x.bin, which can be downloaded from www.moxa.com. You

must first download this file to your PC, and then use Console Terminal or Telnet Console to copy

the file to the EM-1220-LX.

You can save this file to the EM-1220-LX’s RAM disk, and then upgrade the kernel. The

following is a step-by-step example.

To enable the RAM disk, use the following command:

/>upramdisk

As illustrated below, after executing “upramdisk”, you may use “mount” to determine if the new

ramdisk was created successfully or not.

Use the following command to navigate to the device node:

/>cd ramdisk

Use the built-in FTP client to download the file em1220-1.x.bin from the PC.

/ramdisk>ftp <destination PC’s IP>

ftp> bin

ftp> get em1220-1.x.bin

Use the upkernel command to upgrade the kernel and root file system.

/ramdisk>upkernel em1220-1.x.bin

/ramdisk>reboot
