Description

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 Comtrol's new discovery protocol. This verifies that
a Linux kernel image exists in NAND, then copies it to RAM and
starts the IO-Link Master.

The U-Boot version is displayed after the image name.

FPGA

The FPGA partition/image contains configuration data used by
programmable hardware within the IO-Link Master unit.

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 IO-Link
Master. The IO-Link Master automatically reloads the Backup
uImage if the file system corrupted.

The uImage version is displayed after the Primary/Backup uImage.

Application Base

The Application Base image comprises a flash-resident file system
containing application 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 subassemblies in the Application Base image are
displayed in the lower portion of this page.

The Application Base assembly has a 2-tuple version number: (for
example, 1.10).

Application subassemblies have 3-tuple or 4-tuple version numbers (for example, 1.10.1). The
first two values in a subassembly version correspond to the version of the application base
assembly for which it was built and tested.
