    2222=== Getting SoCLib ===

    2626=== SoCLib platform description ===
    2727
    2828The SoCLib source tree contains a platform dedicated to this tutorial:
    29 {{{soclib/soclib/platform/topcells/caba-vgmn-mutekh_soclib_tutorial/}}}
     29[soclib:source:trunk/soclib/soclib/platform/topcells/caba-vgmn-mutekh_soclib_tutorial/]

    3131=== Getting the cross-compilers ===
    … …  
    8686=== Writing the MutekH configuration ===
    8787
    88 The MutekH configuration for the 4 Mips processors platform is in the [source:trunk/mutekh/examples/hello/config examples/hello/config] file.
     88The MutekH configuration for the hello application is in the [source:trunk/mutekh/examples/hello/config examples/hello/config] file.
    8989
    9090This file only holds information about the application (here a simple pthread application) and relies upon files in the [source:trunk/mutekh/examples/common@1183 examples/common] directory for the platform definitions.
    … …  
    9898The MutekH software uses hardware enumeration to get details about available hardware in the platform, so the `CONFIG_ARCH_DEVICE_TREE` token is defined in the [source:trunk/mutekh/examples/common/platforms-soclib.conf@1183 examples/common/platforms-soclib.conf] configuration file. It will let the kernel get the platform layout description from a FlattenedDeviceTree which will be built into the kernel.
    9999
    100 Therefore, the build also compiles the correct FlattenedDeviceTree from the platform name.
     100The build system also compiles the correct FlattenedDeviceTree from the platform name, see [source:trunk/mutekh/examples/common/Makefile@1183 examples/common/Makefile].
    101101
    102 The current FlattenedDeviceTree source file is
    103 [source:trunk/mutekh/examples/common/pf_soclib_tutorial_ppc.dts examples/common/pf_soclib_tutorial_ppc.dts],
    104 [source:trunk/mutekh/examples/common/pf_soclib_tutorial_arm.dts (for arm)],
    105 [source:trunk/mutekh/examples/common/pf_soclib_tutorial_mips.dts (for mips)].
     102The used FlattenedDeviceTree source file are in
     103[source:trunk/mutekh/examples/common/ examples/common/]:
     104[source:trunk/mutekh/examples/common/pf_soclib_tutorial_ppc.dts pf_soclib_tutorial_ppc.dts],
     105[source:trunk/mutekh/examples/common/pf_soclib_tutorial_arm.dts pf_soclib_tutorial_arm.dts],
     106[source:trunk/mutekh/examples/common/pf_soclib_tutorial_mips.dts pf_soclib_tutorial_mips.dts].

    107 === Compiling the application along with MutekH ===
     108=== Configuring the application along with MutekH ===
    108109
    109110The MutekH kernel and the application may be built out of the source tree.
    … …  
    121122   MutekH build option list (target architecture, cpu type, …)
    122123
    123 See the `config.mk` file in the tutorial platform directory for more information.
     124These variables are already set in the `config.mk` file to target the hello demo application.
     125
     126Inside `config.mk`, you'll also find a `CPU` variable that determines which CPU to use in the simulator platform.
     127
     128See the comments in `config.mk` for more information.
     129
     130=== Compiling the application along with MutekH ===
     131
     132To compile the kernel with the application, just run `make` with the path to MutekH source directory:
    124133
    125134{{{
    … …  
    128137}}}
    129138
    130 This will build the MutekH kernel along with the application.
    131 You can still build MutekH separately as explained in the first part. The simulator can then be built using:
    132 
    133 {{{
    134 $ cd soclib/soclib/platform/topcells/caba-vgmn-mutekh_tutorial
    135 $ make system.x
    136 }}}
     139This will build the MutekH kernel along with the application, and the correct simulator.
    137140
    138141== Execution ==
    139142
    140 You can optionally pass an alternative kernel to the simulator, but this defaults to the correct kernel name if you followed the tutorial until here.
     143Simply run the simulator:
    141144{{{
    142 $ ./system.x mutekh/kernel-soclib-ppc.out
     145$ ./simulation.x
    143146}}}
