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.
