** Prerequisites
#+begin_src bash :noeval
sudo emerge -a sys-apps/lsb-release
#+end_src

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

#+begin_src bash :noeval
mkdir -p ~/Documents/MicrochipInstallers
cd ~/Documents/MicrochipInstallers
mv ~/Downloads/libero_soc_*.*_web_lin.zip .
unzip libero_soc_*.*_web_lin.zip
#+end_src

*** Download SoftConsole
Download the latest version from [[https://www.microchip.com/en-us/products/fpgas-and-plds/fpga-and-soc-design-tools/soc-fpga/softconsole][here]].
#+begin_src bash :noeval
mkdir -p ~/Documents/MicrochipInstallers
cd ~/Documents/MicrochipInstallers
mv ~/Downloads/Microchip-SoftConsole-*.*-RISC-V-*-linux-x64-installer.run .
#+end_src

** Install

*** Setup
#+begin_src bash :noeval
export INSTALL_DIR=/opt/microchip
sudo mkdir -p $INSTALL_DIR
sudo chown $USER:$USER $INSTALL_DIR
#+end_src

*** Install Libero
Installer Directions:
- Install Directory: $INSTALL_DIR/Libero_SoC_<version_major>.<version_minor>
- Common Directory: $INSTALL_DIR/common
- Install Set: Everything

#+begin_src bash :noeval
cd ~/Documents/MicrochipInstallers
./Libero_SoC_*.*_Web.bin
#+end_src

**** 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:

#+begin_example
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)
#+end_example

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's provides files via $LD_LIBRARY_PATH. I've also chosen to do this with git commits so you don'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)
#+begin_src bash :noeval
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
#+end_src

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
#+begin_src bash :noeval
cd ~/Documents/MicrochipInstallers
./Microchip-SoftConsole-*.*-RISC-V-*-linux-x64-installer.run
#+end_src


** Post-Install
#+begin_src bash :noeval
sudo $INSTALL_DIR/Libero_SoC_*.*/Logs/req_to_install.sh
#+end_src

*** Installing FlashPro Drivers
You need to have the FlashPro device to install these, so ignore this if you don't have a FlashPro device.

**** FlashPro 5
#+begin_src bash :noeval
sudo $INSTALL_DIR/Libero_SoC_v2023.1/Libero/bin/udev_install
#+end_src

**** FlashPro 6
#+begin_src bash :noeval
sudo $INSTALL_DIR/Libero_SoC_v2023.1/Libero/bin/fp6_env_install
#+end_src

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

#+begin_src bash :noeval
mkdir -p $INSTALL_DIR/Libero_SoC_v2023.1/license
cp /path/to/license /opt/microchip/Libero_SoC_v2023/license
#+end_src

*** Installing the Licensing Daemon
#+begin_src bash :noeval
sudo cp scripts/libero-license.service /etc/systemd/user
#+end_src

* Install Yocto Ecosystem
** Prerequisites
#+begin_src bash :noeval
sudo emerge -pv gawk wget dev-vcs/git diffstat unzip sys-apps/texinfo chrpath socat libsdl xterm bmap-tools repo
#+end_src

#+begin_src bash :noeval
sudo emerge -a
#+end_src

** Create the Yocto Workspace
#+begin_src bash :noeval
mkdir yocto-dev && cd yocto-dev
repo init -u https://github.com/polarfire-soc/polarfire-soc-yocto-manifests.git -b main -m default.xml
#+end_src

** Update the repo workspace
#+begin_src bash :noeval
repo sync
repo rebase
#+end_src

** Setup the Bitbake environment
#+begin_src bash :noeval
. ./meta-polarfire-soc-yocto-bsp/polarfire-soc_yocto_setup.sh
#+end_src

** Optimize your build environment
Yocto builds take a very long time. We can optimize this.

#+begin_src bash :noeval
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
#+end_src

** Build the Disk Image
#+begin_src bash :noeval
cd $PROOT
bitbake mpfs-dev-cli
#+end_src





* Creating a Bootable Yocto Linux Image
We have two options: Create a new workspace, or we can use this repo as a workspace because this repo is my working workspace.
** Create a workspace (OPTIONAL)
#+begin_src
mkdir yocto-dev && cd yocto-dev
repo init -u https://github.com/polarfire-soc/polarfire-soc-yocto-manifests.git -b main -m default.xml
#+end_src

** Update the repo workspace
#+begin_src bash :noeval
repo sync
repo rebase
#+end_src

** Set up the Bitbake environment
#+begin_src bash :noeval
. ./meta-polarfire-soc-yocto-bsp/polarfire-soc_yocto_setup.sh
#+end_src

** Building Board Disk Image

*** Building a Linux Image with a root file system (RootFS)
#+begin_src bash :noeval
MACHINE=icicle-kit-es bitbake mpfs-dev-cli
#+end_src

*** Building a RAM-based Root Filestystem
#+begin_src bash :noeval
MACHINE=icicle-kit-es bitbake -R conf/initramfs.conf mpfs-initramfs-image
#+end_src

*** Building a Linux Image for an external QSPI flash memory

*** Flashing an SD Card
#+begin_src bash :noeval
zcat build/tmp-glibc/deploy/images/icicle-kit-es/mpfs-dev-cli-icicle-kit-es.wic.gz | sudo dd of=/dev/sdX bs=4096 iflag=fullblock oflag=direct conv=fsync status=progress
