|

# Description:
|
||||
# -----------
|
||||
# Scenario #1
|
||||
# -----------
|
||||
# This utility was developed by RidgeRun for the
|
||||
# purpose of converting a standard binary executable
|
||||
# image (such as ELF) into a special format (RR
|
||||
# format) suitable for quick downloads to the target
|
||||
# TI925 RidgeRun Bootloader (rrload). The image is
|
||||
# produced by constructing a special header which is
|
||||
# then tacked onto the front of the supplied binary
|
||||
# image. The resulting binary image is smaller than
|
||||
# what would normally be encountered with traditional
|
||||
# download formats (such as SREC or uuencoded; both
|
||||
# ascii based). The special header at the front of the
|
||||
# image is used to guide the target's rrload (a
|
||||
# booloader developed by RidgeRun Inc). The header
|
||||
# data contains a field representing the total byte
|
||||
# count of the binary data following the header as
|
||||
# well as a field that indicates the load address of
|
||||
# run image. Additionally, a field exists in the
|
||||
# header which indicates the image's entry point which
|
||||
# could be called by the bootloader to invoked the
|
||||
# just downloaded program.
|
||||
# -----------
|
||||
# Scenario #2
|
||||
# -----------
|
||||
# If the supplied image is not a standard binary
|
||||
# executagle image then that is ok too, a header is
|
||||
# constructed and tacked onto the front of the supplied
|
||||
# binary data forming the new binary image (in rr format).
|
||||
# In this case the EntryAddr is set to 0xFFFFFFFF by
|
||||
# default and the LoadAddr is set to 0x00000000 by
|
||||
# default unless otherwise indicated by command line
|
||||
# arguments -LEntry and -LAddr which if used are assumed
|
||||
# to be in hexidecimal units.
|
||||
#
|
||||
# -----------
|
||||
# Scenario #3
|
||||
# -----------
|
||||
#
|
||||
# Read/Write file system (like JFFS) that will not
|
||||
# work if rrload stores a 20 byte header at the beginning
|
||||
# of the flashed component image
|
||||
#
|
||||
# mkimage [--NoHeader ] <input-bin> <out-RR>
|
||||
#
|
||||
# Usage:
|
||||
# mkimage [--LAddr h] [--EAddr h] [--NoHeader] <input-bin> <out-RR>
|
||||
#
|
||||
# Examples:
|
||||
# $ mkimage linux linux.rr
|
||||
# ..or..
|
||||
# $ mkimage -LAddr 10008000 -EAddr 10008000 vmlinux vmlinux.rr
|
||||
# ..or..
|
||||
# $ mkimage --NoHeader fileSys.gz fileSys.gz.rr
|
||||
# ..or..
|
||||
# $ mkimage --LAddr A00 fileSys.gz fileSys.gz.rr
|
||||
# ..or..
|
||||
# $ mkimage --LAddr A00 fileSys.gz fileSys.gz.rr
|
||||
# ^
|
||||
# |
|
||||
# Assumed hex units.
|
||||
# Please omit the
|
||||
# leading "0x".
