Nuttx can be configured differently depending on what we want.
The possible configs are:
* compal_e88/nsh_highram : for the gta02 using the osmocon for the romloader
* compal_e99/nsh_highram : for the c155 using osmocon + loader.compalram.bin as a loader
* compal_e99/nsh_compalram : for the c155 using osmocon to load it

nsh is the nuttx shell(nuttx can also run standalone apps without a shell).

== standalone nuttx ==
if you want a standalone nuttx(without linking to osmocombb for the drivers) do the following:
{{{
make clean
make distclean
}}}

Remove sercomm directories:
{{{
$ rm -rf drivers/sercomm
$ rm -rf include/nuttx/sercomm
}}}

Remove sercomm reference at drivers/Makefile: driver/Makefile:
{{{
-include sercomm/Make.defs
}}}

Then configure nuttx

Then apply manually the following pseudo-diff in nuttx/.config :
{{{
-CONFIG_DISABLE_ENVIRON=y
+CONFIG_DISABLE_ENVIRON=n
+CONFIG_STDIO_LINE_BUFFER=y
}}}
And then remove the following lines from nuttx/Make.defs:
{{{
OSMODIR = $(TOPDIR)/../../osmocom-bb
EXTRA_LIBS = $(OSMODIR)/src/target/firmware/comm/libcomm.a \
$(OSMODIR)/src/shared/libosmocore/build-target/src/.libs/libosmocore.a \
$(OSMODIR)/src/target/firmware/calypso/libcalypso.a \
$(OSMODIR)/src/target/firmware/comm/libcomm.a
# ^^^ Stupid hack! Why do I have to put it twice???
}}}
And then build as usual.
