At present, the system only supports a serial console and timer
interrupts so there is not to much that you can do with it. But I
would be happy to work with anyone who is interested in using it.
General instructions.
1. Download build-0.1.0.tar.gz and nuttx-0.2.3.tar.gz into the same
<directory>. These are the current versions as of this writing
(but could very well new older release now).
2. Unpack, you should now have <directory>/buildroot and
<directory>/nuttx-0.2.3
3. Rename nuttx-0.2.3 to nuttx
4. Configure NuttX:
cd <directory>/nuttx/tools
./configure.sh ntosd-dm320
5. Build the toolchain:
cd <directory>/buildroot
cp configs/c5471-defconfig .config
make oldconfig
make
6. Build Nuttx:
cd <directory>nuttx
. ./setenv.sh
make
mv nuttx /tftpboot/nuttx.dm320
7. Configure the OSD u-boot:
Neuros Devboard > set ipaddr yy.yy.yy.yy
Neuros Devboard > set serverip xx.xx.xx.xx
Neuros Devboard > ...
Neuros Devboard > run update-ipstatic
where yy.yy.yy.yy is the OSD IP address and xx.xx.xx.xx is
the host PC address.
8. Load and run nuttx from uboot
tftpboot xx.xx.xx.xx nuttx.dm320
go 1008000
What will run is an a simple OS test that will verify many of the
features of the OS. (this is nutts/examples/ostest).
