Hi,
How do i get the "console channel is configurable" option
enabled under the ROM monitor support using the ecos configuration
tool 2.11.
well, currently this option is disabled while building the redboot.img
and i guess bcoz of this, i m not able to see the diagnostic serial
output on my hyperterminal.
If you use the configuration tool you should be able to see what options
this option depends on in the pane on the right. If editting ecos.ecc, you
should be able to determine it from the text inside to find out why it is
inactive.
But I'll give you some help anyway. The common HAL's CDL includes:
calculated { !CYGSEM_HAL_VIRTUAL_VECTOR_INHERIT_CONSOLE \
&& !CYGDBG_HAL_DIAG_TO_DEBUG_CHAN }
So it is not configurable if either of the above options are enabled. The
former is enabled by default so that the console channel is preserved from
the ROM monitor. For example if debugging via ethernet your channel would
disappear entirely, instead going to the serial port, if you disabled
CYGSEM_HAL_VIRTUAL_VECTOR_INHERIT_CONSOLE.
btw, were can we change the redboot.img base address value..?
You need to edit the MLT files found in the include/pkgconf directory of
your chosen platform HAL.
