  1. MEOS IPC Group97/05/20 meeting Sean Lin

  2. Working Progress • Survey the booting sequence of OKL4 • platform/s3c2410/pistachio/src/head.spp => _start • arch/arm/pistachio/src/init.cc => PlatformSupport::arch_init() • arch/arm/pistachio/src/init.cc => init_memory() • arch/arm/pistachio/src/init.cc => startup_system_mmu() • platform/s3c2410/pistachio/src/plat.cc => Platform::init()

  3. Review The Goal • First Stage • Port OKL4 to PAC PMP (ARM922T + PAC DSP)

  4. Partition The Work • Architecture • Survey the PAC PMP architecture • OKL4 • Simulation environment • Building system • Modify the source code • Boot Loader • Choose the boot loader • Modify the source code

  5. More Detail • Simulation environment • How the GTA01 machine run? • What is the boot loader on QEMU? • Boot loader • What action between OKL4 and boot loader • Ask Kashin

  6. More Detail (cont.) • Building System • SCons、Magpie、PyElf、Pexpect… • Something confused Memory Relationship

  7. More Detail (cont.) Driver Relationship

  8. More Detail(cont.) • OKL4 • How to write a driver on OKL4?

  9. Working List • Survey the architecture • Try the simulation environment • Port boot loader • Port OKL4 • Survey the building system

  10. Diagram Choose the boot loader Port boot loader Architecture survey Port OKL4 Write driver needed Boot loader on QEMU Simulation environment Memory relationship Driver relationship Code generation

  11. OKL4 Reference • http://wiki.ok-labs.com/ • Get Start Guide • http://wiki.ok-labs.com/GetStarted • How to boot • http://wiki.ok-labs.com/BootingUp • …
