I check the ecos-2.0-ref-letter.pdf, it says
==========================
Console output configuration is either inherited from the ROM monitor
launching the application, or it is speci-
fied by the application. This is controlled by the new option
CYGSEM_HAL_VIRTUAL_VECTOR_INHERIT_CONSOLE
which defaults to enabled when the configuration is set to use a ROM
monitor.
==========================
but in hal_arm_snds.cdl, there is no cdl_option for
CYGSEM_HAL_USE_ROM_MONITOR
(hal_arm_at91.cdl have this cdl_option), maybe it need to fixed? I am not
sure......
I add this option and recompile the redboot and kernel test program.
It's happy that redboot[ROMRAM] can use both way to run the test program,
but it's sad that redboot[ROM] fail on both.
can anyone tell me why?

This should not be set to anything for "user" programs.
If things are configured properly, the application program will
inherit the I/O in the mode that it was in when the program starts.
Thus, if you use RedBoot 'load' and 'go' commands, you get plain,
non-mangled output. If you are using GDB, you get GDB mangled output.
