Images
The following table discusses IOLM images.
IOLM Images
U-Boot Bootloader
U-Boot is a high-level Bootloader that has networking and console
command-line capabilities. Among other things, it implements a TFTP server
and Emerson Corporation's discovery protocol.
This verifies that a Linux kernel image exists in NAND, then copies it to RAM
and starts the IOLM. The U-Boot version is displayed after the image name.
FPGA
The FPGA partition/image contains configuration data used by
programmable hardware within the IOLM unit.
FPGA images are unique to the hardware and protocol type. Make sure you
download the correct image for your platform.
uImage - Primary/
Backup
The uImage contains the Linux kernel and the RAM-resident root file system.
It does not contain industrial protocol support or application-specific
features.
There is a Primary and Backup version loaded on the IOLM. The IOLM
automatically reloads the Backup uImage if the file system is corrupted.
The uImage version is displayed after the Primary/Backup uImage.
Application Base
The Application Base image comprises a flash-resident file system
containing applications and protocol support.
The Application Base is built from a collection of application subassemblies --
each of which may be updated individually between releases of the
application base as a whole.
The application sub-assemblies in the Application Base image are displayed
in the lower portion of the
SOFTWARE
page.
The Application Base assembly has a 3-tuple version number: (for example,
1.3.18).
