Synthetic base build
- build the application
ecosynth
- See
- ~ECOS/ecos-cvs/packages/hal/synth/arch/current/doc/
- ~ECOS/ecos-cvs/packages/hal/synth/arch/current/host; run
configure in directory ~ECOS/ecos-build/synth/ecosynth/hal:
| $ ~ECOS/ecos-cvs/packages/hal/synth/arch/current/host/configure \
|
| --prefix=~ECOS/ecos-build/synth/bin
|
| $ make && make install
|
Synthetic network build
- build the intermediate application
rawether
- See
- ~ECOS/ecos-cvs/packages/devs/eth/synth/ecosynth/current/doc/
- ~ECOS/ecos-cvs/packages/devs/eth/synth/ecosynth/current/host; run
configure in directory ~ECOS/ecos-build/synth/ecosynth/eth:
| $ ~ECOS/ecos-cvs/packages/devs/eth/synth/ecosynth/current/host/configure \
|
| --prefix=~ECOS/ecos-build/synth/bin
|
| $ make && sudo make install
|
The latter step is necessary because the executable created (rawether) needs to be setuid-root.
Linux setup for Synthetic network stuff
We use dhcp to assign an IP address to our eCos synth app
- See Sergei Gavrikov's instructions: [[1]] and [[2]]
- But some things didn't work for me so I try to repeat what I did:
| $ sudo apt-get install uml-utilities # for tunctl
|
| $ sudo apt-get install dhcp3-server
|
Add to /etc/network/interfaces
| iface tap0 inet manual
|
| up tunctl -t tap0
|
| up ip l set up dev tap0
|
| up ip a add 10.1.1.1/24 brd + dev tap0
|
| down ip l set down dev tap0
|
| down tunctl -d tap0
|
Edit /etc/default/dhcp3-server to contain
Edit /etc/dhcp3/dhcpd.conf and add
| # For the eCos synth server thingy, we configure an ethertap
|
| subnet 10.1.1.0 netmask 255.255.255.0 {
|
| range 10.1.1.20 10.1.1.30;
|
| }
|
Make rutger owner of tap0 so we can run the binary as rutger, not as root:
| $ sudo tunctl -u rutger -t tap0
|
| $ sudo chown rutger:rutger /dev/net/tun
|
Bring up tap0
Restart dhpc3-server
| $ sudo /etc/init.d/dhcp3-server restart
|
Create a binding for ethertap tap0 in file ~ECOS/ecos-build/synth/my.tdf (now in SVN):
| my.tdf --
|
| synth_device ethernet {
|
| eth0 ethertap tap0
|
| }
|
Synth application
Add to your PATH the directory ~ECOS/ecos-build/synth/bin/libexec
Open up the 10.1.1.x range in /etc/hosts.allow:
Run ping test as
| $ cd ~ECOS/ecos-build/synth
|
| $ ./linux_install/tests/net/common/current/tests/ping_test -nw -io -t my.tdf
|
Synth framebuffer support
| $ cd ~ECOS/ecos-build/
|
| $ ~ECOS/ecos-cvs/packages/devs/framebuf/synth/current/host/configure --prefix=./bin
|
| $ cd ~ECOS/ecos-build/synthecosynth/framebuffer
|
| $ make && make install
|
| $ export ECOS_REPOSITORY=~ECOS/ecos-cvs/packages
|
| $ export PATH=$PATH:~ECOS/ecos-build/synth/bin/libexec
|
