About the Board

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)

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

Update the repo workspace

repo sync
repo rebase

Set up the Bitbake environment

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

Building Board Disk Image

Building a Linux Image with a root file system (RootFS)

MACHINE=icicle-kit-es bitbake mpfs-dev-cli

Building a RAM-based Root Filestystem

MACHINE=icicle-kit-es bitbake -R conf/initramfs.conf mpfs-initramfs-image

Building a Linux Image for an external QSPI flash memory

Flashing an SD Card

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
