build-redboot

redboot在Tensilica平台上的源码

#!/bin/sh
#
#  Script to build RedBoot from sources.
#  Sources are based on eCos 1.3.1 with changes made by Tensilica
#  to support the Xtensa architecture and related development boards.
#
#  Requires Tensilica Tools (RB-2007.2 or later) and associated core package
#  for the Tensilica core you are targeting.  The core package must have been
#  built with support for the relevant board, in order for the RedBoot
#  linker script tarball to be present in the Tensilica core package
#  (in <xtensa_root>/xtensa-elf/src/redboot/mlt_<board>_files.tar).
#
#  Requires Tcl (only version 8.4 has been tested).
#
#  Requires the ecosconfig binary (x86 linux-2.6 version provided).
#
#  To build, edit the script to properly set these variables:
#	board, ecosconfig, mlt_path, build
#  then just execute the script in the directory containing the
#  redboot-src.tgz package.
#  The resulting redboot binaries are in $build/install/bin .


#  Verify that Tensilica Tools are accessible.
#  XTENSA_SYSTEM and XTENSA_CORE environment variables must be properly set,
#  and Tensilica Tools must be in the PATH.
