NuttX on the Neuros Technology OSD ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ References: ^^^^^^^^^^^ http://wiki.neurostechnology.com/index.php/Main_Page http://wiki.neurostechnology.com/index.php/OSD_Developer_Home http://wiki.neurostechnology.com/index.php/DM320_Platform_development http://wiki.neurostechnology.com/index.php/The_Neuros_and_Open_Source ... Status: ^^^^^^^ 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 . These are the current versions as of this writing (but could very well new older release now). 2. Unpack, you should now have /buildroot and /nuttx-0.2.3 3. Rename nuttx-0.2.3 to nuttx 4. Configure NuttX: cd /nuttx/tools ./configure.sh ntosd-dm320 5. Build the toolchain: cd /buildroot cp configs/c5471-defconfig .config make oldconfig make 6. Build Nuttx: cd 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).
