I think this is good, but maybe we can mention to refer to Documentation/filesystems/ramfs-rootfs-initramfs.rst for more details on this? Also, it may be helpful to mention we can get pre-built busybox rootfs images here: https://github.com/stffrdhrn/or1k-rootfs-build/releases But if we do that then it would be better to show how to use thos rootfs images, which maybe something better we have in our openrisc/tutorials[0]. -Stafford [0] https://github.com/openrisc/tutorials > 3) Running on FPGA (optional) > > The OpenRISC community typically uses FuseSoC to manage building and > programming > -- > 2.37.2 >
