Note that you need an appropriate version of the Linux kernel tree, RTAI and RTnet. Furthermore, PowerPC support is not included in the normal RTAI patches, e.g. the one you mentioned above. I suggest to use: - A recent version of the DENX linuxppc_2_4_devel tree (check http://www.denx.de for further information), which is a 2.4.25 kernel known to work well on MPC 8xx. There are rather recent tarballs at ftp://ftp.denx.de/pub/ppc/linux/ e.g. linuxppc_2_4_devel-2005-09-15-2320.tar.bz2 in case you don't have CVS or GIT access. - A recent RTAI kernel patch from ftp://ftp.denx.de/pub/RTAI/patches, e.g. patch-denx-linuxppc_2_4_devel-2005_06_23_1722 should be OK: $ export CROSS_COMPILE=ppc_8xx- $ tar xjf linuxppc_2_4_devel-2005-09-15-2320.tar.bz2 $ cd linuxppc_2_4_devel-2005-09-15-2320 $ patch -p1 -b -z.ORIG < \ ../patch-denx-linuxppc_2_4_devel-2005_06_23_1722 $ make TQM862M_config $ make menuconfig ... [ ] CPM SCC Ethernet ... $ make dep $ make uImage Also read ftp://ftp.denx.de/pub/RTAI/README, please. - RTnet 0.8.3 and head of CVS of the RTAI from the "stromboli" branch. There is a daily snapshot of the CVS tree available at https://gna.org/cvs/?group=rtai $ tar xzf rtai-snapshot.tar.gz $ cd rtai/stromboli/ $ export CROSS_COMPILE=ppc_8xx- $ make ... Enter location of Linux source tree [...]: ... $ make $ cd ../.. $ tar xjf rtnet-0.8.3.tar.bz2 $ cd rtnet-0.8.3 $ export DESTDIR=/opt/eldk/ppc_8xx $ ./configure --host=ppc-linux --build=i686-linux \ --with-rtai=/temp/rtai/devel/rtai/stromboli --prefix=/usr/realtime \ --enable-scc-enet --enable-fec-enet $ make $ make install $ ls -l $DESTDIR/usr/realtime/modules -rw-r--r-- 1 wolf badboys 18070 Oct 3 13:37 rtai_rtdm.o -rw-r--r-- 1 wolf badboys 45453 Oct 3 13:37 rtcfg.o -rw-r--r-- 1 wolf badboys 3681 Oct 3 13:37 rt_loopback.o -rw-r--r-- 1 wolf badboys 17342 Oct 3 13:37 rtmac.o -rw-r--r-- 1 wolf badboys 9665 Oct 3 13:37 rt_mpc8xx_enet.o -rw-r--r-- 1 wolf badboys 9722 Oct 3 13:37 rt_mpc8xx_fec.o -rw-r--r-- 1 wolf badboys 75003 Oct 3 13:37 rtnet.o -rw-r--r-- 1 wolf badboys 23163 Oct 3 13:37 tdma.o I have tested RTnet on MPC 8xx with this combination recently.
