You pass it to the configure line as BSP_CONSOLE_BAUD=9600


With the old build system, the steps are basically:

- bootstrap (if you haven't done so) in the rtems source directory:

   path/to/rtems-source-builder/source-builder/sb-bootstrap

- create a build directory and call configure:

   path/to/rtems-sources/configure \
     --target=$(MACHINE)-rtems5 \
     --prefix=$(PREFIX) \
     --enable-posix \
     --enable-rtemsbsp=$(BSP) \
     --enable-maintainer-mode \
     --disable-networking \
     --enable-tests=samples \
     CONSOLE_POLLED=1 \
     BSP_CONSOLE_BAUD=9600

   NOTE: This is copied from one of my older builds. You most likely 
have to adapt some options (like posix or networking).

- make and install the bsp:

   make
   make install

I'm not 100% sure but I would say: Yes, it is.

Be carefull: There is libbsd and there is the legacy stack. If your BSP 
uses the legacy stack that is the one that you enable with the configure 
option. On the 5 branch it is still integrated in RTEMS (I think - 
Vijay: correct me if I'm wrong). If your BSP uses libbsd, that would be 
an extra build.

If you used --with-rtems-legacy-network on the RSB, I think you only 
have to use --enable-networking during configure.

Best regards

Christian
