Displaying or Updating Flash Memory
The Flash Update display includes information about the current images loaded in Flash memory.
You may update the embedded application image or bootstrap image in Flash memory. Before
updating a Flash image, you must configure a TFTP server on the target server system and install
the new Flash image in the appropriate location, which is usually relative to the TFTP
root directory.
To display Flash image information or update an image:

From the Main Menu, select

The Application Image section includes the version number, size and internal slot number for
the Primary embedded application image. The previously installed image is maintained as a
backup; the Backup field contains its values.
The Bootstrap Image section indicates the version number, size and internal slot number for
the embedded kernel image. The previously installed image is maintained as a backup. The
Bootloader field indicates the version number and size of the bootloader image. The FPGA
field indicates the version number and size of the FPGA.

checkbox. It is generally recommended that this
checkbox be disabled.
