Setting up the QEMU Platform Project

1. File -> New -> DDC-I Deos Platform Projects
2. Select a Deos reference platform -> qemu-arm
3. Set the IP Addresses:
   • In the workspace view to the left:
   • In your Platform Project
   • Under Complete Integration
   • Double click Kernel Files
   • Right click on lwip.config
   • Copy for Editing...
   • In the file that now opened:
     • change the IP address from 192.168.19.17 to 10.0.2.15
     • change the netmask from 255.255.255.254 to 255.255.255.0 (This is the default guest IP & netmask used by QEMU's SLiRP)
4. Add the QEMU remote target
   • In the Target Manager at the bottom left, click New Remote Target (icon is a T-Junction with a plus)
   • Hostname is localhost
   • Platform Project as created before
   • OK
5. Launch QEMU and connect
   • In the Target Manager at the bottom left, click Launch Emulator (icon is a green circle with a white triangle)
   • Right click Status Monitor -> enable
   • Right click Load List Manager -> enable
   • Note Ping does not work, QEMU SLiRP does not implement ICMP

Launch a new project

1. File -> New -> DDC-I Deos Example Projects
2. Tick Kernel -> [ ] hello-world
3. Select Target to be ARM
4. Add the example project to the platform project
   • In the workspace view, drag the example project over the platform project, drop it there
   • Click OK

Compiling & running example Rust App

1. Launch the IDE
   • ./scripts/run-ddc-i-deos.sh
2. Compile the Rust code
   • Use the podman exec command printed by the script from step 1 to get a shell
   • Navigate to the example demo
   • Run cargo build
3. Copy the generated executable over the example executable from the example project
   • The Rust binary is target/armv7-unknown-deos-eabihf/debug/deos-api.exe (which actually is an ELF)
   • The final hello-world executable is hello-world/output/arm-eabi/diagnostic/hello-world.exe
   • cp examples/armv7l-hello-world/target/armv7-unknown-deos-eabihf/debug/deos-api.exe OpenArbor/workspace/hello-world/output/arm-eabi/diagnostic/hello-world.exe
4. Upload the new, rusty executable to the DEOS inside QEMU
   • In the Target Manager at the bottom left, click Update Target Load (icon is a green arrow above an envelope)
   • There should be a Will Be Update element in the Synchronize Files tree-view
   • Click OK
5. Finished! On the QEMU window you should now see a different, more rusty number sequence counting the OS ticks.
