[ECOS] building problem with redboot

[Jing Luo <Jing at vicom dot com>]

Hi,

1. I got a building problem when I want to have GDB debug function with
redboot as the following.
The detailed build output is as the attachment.
The prblem is cyg_start have conflict definition in main.c and stubrom.c
when it try to build gdb_module.o.
I choosed CYGBLD_BUILD_GDB_STUBS & CYGBLD_BUILD_COMMON_GDB_STUBS &
CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT in cfgtools.

2. Thanks for your guys' help, I ported redboot to 80200. It can be booted
into redboot now. :-)
But When I load -m xMODEM, it takes about 10 seconds to get 'C' prompt. I
can't figure out why it takes such a long time. The source code only takes
about 500000us. Why?

Thanks,
