Building meta-sgl with kas
Here are simple instructions for getting started building the long-term support release of Yocto (scarthgap). Documentation for kas can be found at https://kas.readthedocs.io/en/latest/
Installing kas
To create a Python virtual environment to install kas run these commands:
bash
python3 -m venv venv
source venv/bin/activate
pip3 install kas
Clone the meta-sgl build branch
After you have sourced the environment where kas is installed you may get the kas configuration by cloning meta-sgl:
bash
git clone https://github.com/elisa-tech/meta-sgl
Running kas
Create a new project directory wherever you want and set the KAS_WORK_DIR environment variable to point to it. Then run kas with the configuration file for Yocto scarthgap release and qemuriscv64.
bash
mkdir $PROJECT_DIR
KAS_WORK_DIR=$PROJECT_DIR
kas build meta-sgl/kas/sgl-scarthgap-qemuriscv64.yml
This should complete successfully and produce an image you can run in QEMU.
bash
build/tmp-glibc/deploy/images/qemuriscv64/core-image-minimal-qemuriscv64.rootfs.ext4
Running QEMU
You can run the images in QEMU by executing them with the proper runtime. Here's an example command:
bash
cd $KAS_WORK_DIR
qemu-system-riscv64 -M virt -m 512M -nographic -kernel build/tmp-glibc/deploy/images/qemuriscv64/Image -append "root=/dev/vda rw console=ttyS0" -drive file=build/tmp-glibc/deploy/images/qemuriscv64/core-image-minimal-qemuriscv64.rootfs.ext4,format=raw,id=hd0 -device virtio-blk-device,drive=hd0 -netdev user,id=net0 -device virtio-net-device,netdev=net0
It would produce output similar to:
OpenSBI v0.9
