RE: [ECOS] MBX stubrom (was [ECOS] loader.bin sources?)

[Gary Thomas <gthomas@cygnus.co.uk>]

Here's the script I use to do this (running on another platform).
Perhaps it will lend some help.  (Note: we're working on improving
both the documentation and procedure for making stubs...)

----------------- STUBS_config ------------------------------------
#! /bin/sh

tcl $1/pkgconf.tcl                                         \
  --target=arm --platform=pid --startup=stubs                   \
  --disable CYGPKG_KERNEL --disable CYGPKG_UITRON               \
  --disable CYGPKG_LIBC --disable CYGPKG_LIBM                   \
  --disable CYGPKG_ERROR --disable CYGPKG_IO                    \
  --disable CYGPKG_IO_SERIAL --disable CYGPKG_DEVICES_WALLCLOCK \
  --disable CYGPKG_DEVICES_WATCHDOG
