Obsolete support for the 8051 family. Trying to maintain compatibility with this family is too much effort and there has never really been a successful NuttX impplementation on these parts

pjrc-8051 README
|
|
||||||
^^^^^^^^^^^^^^^^
|
|
||||||
|
|
||||||
This port uses the PJRC 87C52 development system and the SDCC toolchain.
|
|
||||||
|
|
||||||
The PJRC 87C52 development system can be obtained from http://www.pjrc.com/.
|
|
||||||
|
|
||||||
The SDCC toolchain is available from http://sdcc.sourceforge.net/. All
|
|
||||||
testing has been performed using verison 2.6.0 of the SDDC toolchain.
|
|
||||||
|
|
||||||
Building the SDCC toolchain
|
|
||||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
||||||
|
|
||||||
The SDCC toolchain is built with the standard configure/make/make install
|
|
||||||
sequence. However, some special actions are required to generate libraries
|
|
||||||
compatible with this build. First start with the usual steps
|
|
||||||
|
|
||||||
download
|
|
||||||
unpack
|
|
||||||
cd sdcc
|
|
||||||
./configure
|
|
||||||
make
|
|
||||||
|
|
||||||
But before installing, we need to apply a patch to the SDCC 2.6.0 source.
|
|
||||||
WARNING: This patch is specific to the particular combination of CFLAGS
|
|
||||||
that are used in the compilation. If you change Make.defs, then you will
|
|
||||||
likely have to change the patch as well.
|
|
||||||
|
|
||||||
Apply sdcc-2.6.0.patch
|
|
||||||
cd sdcc/device/lib
|
|
||||||
make model-mcs51-stack-auto
|
|
||||||
|
|
||||||
Then
|
|
||||||
|
|
||||||
cd sdcc
|
|
||||||
make install
|
|
||||||
|
|
||||||
Status
|
|
||||||
^^^^^^
|
|
||||||
|
|
||||||
On December 9, 2012, I made updates so that the 8051 port could use the
|
|
||||||
newest SDCC toolchain (a pre-3.2.1 at that time). However, when I attempted
|
|
||||||
to build the PJRC-8051 configuration, I got type incompatibility errors
|
|
||||||
from sched/os_bringup.c. From what I gather by googling, this is a compiler
|
|
||||||
bug related to the --stack-auto option.
|
|
||||||
|
|
||||||
I have not been successful working around those bugs and I believe that
|
|
||||||
these are 8051-related bugs in the SDCC toolchain. This needs to be
|
|
||||||
revisited with a later version of SDCC.
|
|
||||||
|
|
||||||
This configuration was last successfully built and tested with a ca.
|
|
||||||
2.6.0 SDCC release. Support for that older toolchain was removed in
|
|
||||||
NuttX revision -r5423. If you wanted to used those older toolchains,
|
|
||||||
you would need to revert to a pre-r5423 revision.
