# TODO Installing via Portage


<a id="orge000bac"></a>

# Installing Manually


<a id="org0fd2701"></a>

## Prerequisites

    sudo emerge -a sys-apps/lsb-release


<a id="orgbf609ab"></a>

### Download Libero

Download the latest version from [here](https://www.microchip.com/en-us/products/fpgas-and-plds/fpga-and-soc-design-tools/fpga/libero-software-later-versions).

    mkdir -p ~/Documents/MicrochipInstallers
    cd ~/Documents/MicrochipInstallers
    mv ~/Downloads/libero_soc_*.*_web_lin.zip .
    unzip libero_soc_*.*_web_lin.zip


<a id="orgfa083ed"></a>

### Download SoftConsole

Download the latest version from [here](https://www.microchip.com/en-us/products/fpgas-and-plds/fpga-and-soc-design-tools/soc-fpga/softconsole).

    mkdir -p ~/Documents/MicrochipInstallers
    cd ~/Documents/MicrochipInstallers
    mv ~/Downloads/Microchip-SoftConsole-*.*-RISC-V-*-linux-x64-installer.run .


<a id="orgc791c33"></a>

## Install


<a id="org180e2e4"></a>

### Setup

    export INSTALL_DIR=/opt/microchip
    sudo mkdir -p $INSTALL_DIR
    sudo chown $USER:$USER $INSTALL_DIR


<a id="orgfe1c9e4"></a>

### Install Libero

Installer Directions:

-   Install Directory: $INSTALL\_DIR/Libero\_SoC\_<version\_major>.<version\_minor>
-   Common Directory: $INSTALL\_DIR/common
-   Install Set: Everything

    cd ~/Documents/MicrochipInstallers
    ./Libero_SoC_*.*_Web.bin

1.  Gentoo Specific Libero Fixes

    When attempting to run `/opt/microchip/Libero_SoC_v2024.1/Libero/bin64/libero`, you will most likely be met with the following error:
    
        Warning: You are running a version of Suse Linux that is not supported.
         Please refer to Libero SoC Release Note for the detail of supported operating systems.
        /opt/microchip/Libero_SoC_v2024.1/Libero/bin64/libero_bin: /opt/microchip/Libero_SoC_v2024.1/Libero/lib64/rhel/libstdc++.so.6: version `GLIBCXX_3.4.30' not found (required by /usr/lib64/libicuuc.so.74)
    
    The way I chose to combat this was to delete all of the `libstdc++.so.6` files that came with the tools and then supplying the system&rsquo;s provides files via $LD\_LIBRARY\_PATH. I&rsquo;ve also chosen to do this with git commits so you don&rsquo;t have to start all over if you mess up. The git parts are optional but recommended. (Thanks to sam for helping me figure this out)
    
        cd /opt/microchip/Libero_SoC_*.*
        git init
        git add .
        git commit -m "init"
        find . -name "libstdc++.so.6" -type f -or -type l -delete
        git add .
        git commit -m "removed tool specific libstdc++.so.6 files"
        # test it to make sure it launches
        LD_LIBRARY_PATH="/usr/lib/gcc/x86_64-pc-linux-gnu/13" ./Libero/bin64/libero
    
    This should launch and then give you an error saying license not found. This is normal and will be fixed later in the guide.

### Install SoftConsole

    cd ~/Documents/MicrochipInstallers
    ./Microchip-SoftConsole-*.*-RISC-V-*-linux-x64-installer.run


<a id="org1aab735"></a>

## Post-Install

    sudo $INSTALL_DIR/Libero_SoC_*.*/Logs/req_to_install.sh


<a id="orgcec48c8"></a>

### Installing FlashPro Drivers

You need to have the FlashPro device to install these, so ignore this if you don&rsquo;t have a FlashPro device.

1.  FlashPro 5

        sudo $INSTALL_DIR/Libero_SoC_v2023.1/Libero/bin/udev_install

2.  FlashPro 6

        sudo $INSTALL_DIR/Libero_SoC_v2023.1/Libero/bin/fp6_env_install


<a id="org01887da"></a>

### Installing Your License

You can register for a microchip and request a year-long evaluation license here: <https://www.microchipdirect.com/login?redirectTo=%2Ffpga-software-products>

You&rsquo;ll want to get the **LIB-PL-MACID-F-EVAL** license, which is a floating linux license.

    mkdir -p $INSTALL_DIR/Libero_SoC_v2023.1/license
    cp /path/to/license /opt/microchip/Libero_SoC_v2023/license


<a id="orgb0a7b68"></a>

### Installing the Licensing Daemon

    sudo cp scripts/libero-license.service /etc/systemd/user


<a id="orgecf7921"></a>

# Install Yocto Ecosystem


<a id="org2fca117"></a>

    sudo emerge -pv gawk wget dev-vcs/git diffstat unzip sys-apps/texinfo chrpath socat libsdl xterm bmap-tools repo

    sudo emerge -a


<a id="org2f15271"></a>

## Create the Yocto Workspace

    mkdir yocto-dev && cd yocto-dev
    repo init -u https://github.com/polarfire-soc/polarfire-soc-yocto-manifests.git -b main -m default.xml


<a id="orgce514fa"></a>

## Setup the Bitbake environment

    . ./meta-polarfire-soc-yocto-bsp/polarfire-soc_yocto_setup.sh


<a id="orgac0a974"></a>

## Optimize your build environment

Yocto builds take a very long time. We can optimize this.

    mkdir -p ${HOME}/.local/share/yocto/downloads
    mkdir -p ${HOME}/.local/share/yocto/sstate-cache
    mkdir -p ${HOME}/.local/share/yocto/persistent
    cd <project_root>/build/conf/
    
    
    echo '
    BB_NUMBER_THREADS ?= "${@oe.utils.cpu_count()}"
    PARALLEL_MAKE ?= "-j ${@oe.utils.cpu_count() - 1}"
    DL_DIR = "${HOME}/.local/share/yocto/downloads"
    SSTATE_DIR = "${HOME}/.local/share/yocto/sstate-cache"
    PERSISTENT_DIR=${HOME/.local/share/yocto/persistent
    SOURCE_MIRROR_URL ?= "file://${HOME}/.local/share/yocto/downloads"
    INHERIT += "own-mirrors"
    BB_GENERATE_MIRROR_TARBALLS = "1"
    # uncomment to test sources
    # BB_NO_NETWORK = "1"
    
    # remove static deps
    STATICLIBCONF = "--disable-static"
    DISABLE_STATIC:pn-openssl = ""
    DISABLE_STATIC:pn-openssl-native = ""
    DISABLE_STATIC:pn-nativesdk-openssl = ""
    DISABLE_STATIC:pn-libtalloc = ""
    EXTRA_OECONF += "${STATICLIBCONF}"
    ' >> local.conf
