Since different Flash disks have different sizes, it’s a good idea to check the size of your Flash disk

before upgrading the firmware, or before using the disk to store your application and data files.

Use the #df –h command to list the size of each memory block, and how much free space is

available in each block.

The following instructions give the steps required to save the firmware file to the

UC-8410/8416/8418’s RAM disk, and then upgrade the firmware.

1. Type the following commands to enable the RAM disk:

#upramdisk

#cd /mnt/ramdisk

2. Type the following commands to use the UC-8410/8416/8418’s built-in FTP client to transfer

the firmware file (FWR_uc8400_Va.b.c_Build_YYMMDDHH.hfm ) from the PC to the

UC-8410/8416/8418:

/mnt/ramdisk> ftp <destination PC’s IP>

ftp> bin

ftp> get FWR_uc8400_Va.b.c_Build_YYMMDDHH.hfm
