They are effectively just a configuration of eCos. Here's what to do:

1. Create a build directory and cd into it.

2. Run: tclsh <sourcedir>/pkgconf.tcl --target powerpc --platform cogent --startup rom --disable-kernel --disable-uitron --disable-libc --disable-libm --disable-io --disable-io_serial --disable-wallclock --disable-watchdog

Where <sourcedir> is the path to your source repository. Use "cygtclsh80"
in place of "tclsh" if you are on Windows, rather than Unix.

3. Edit pkgconf/hal.h *by hand* and enable the following "#define"s:

CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS
CYGDBG_HAL_DEBUG_GDB_BREAK_SUPPORT
CYGDBG_HAL_DEBUG_GDB_THREAD_SUPPORT
CYG_HAL_ROM_MONITOR

You should also comment out the line:
#define CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT

4. Run: make

5. Run: make -C hal/common/current/src/stubrom

The file hal/common/current/src/stubrom/stubrom will be an ELF excutable
of the ROM. Use powerpc-eabi-objcopy to convert this to the appropriate
format for your PROM burner.

Hmm... perhaps I should put this in the FAQ. It's not very obvious :-).
Can you let me know if this works for you, and I'll do that.

Thanks,
