Root filesystem for risc-v board
|
Pavel Machek
Hi!
So... how do you get root filesystem for RISC-V board? Ideally I'd like to get something Debian based. Best I could try is debootstrap for Debian testing: sudo debootstrap --no-check-gpg --foreign --arch=riscv64 --keyring /usr/share/keyrings/debian-ports-archive-keyring.gpg --include=debian-ports-archive-keyring unstable /some/suitable/dir http://deb.debian.org/debian-ports Unfortunately, I can't get debootstrap --second-stage to work (I get sigsegv in ldconfig, I guess testing may be too experimental?). Is it possible to debootstrap stable or testing distributions? I don't think CIP project provides binary images somewhere. What is recommended way to get a root filesystem? Is there suitable documentation I should follow? Thanks and best regards, Pavel -- DENX Software Engineering GmbH, Managing Director: Wolfgang Denk HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany

Hello Pavel,

We have a development branch in isar-cip-core, by which we can generate a rootfs for QEMU riscv64. https://gitlab.com/cip-project/cip-core/isar-cip-core/-/tree/thond/riscv-dev Please note that this is not an official recipes of isar-cip-core and there is no plan to be merged into master because it uses sid-ports repository. Step to build rootfs (tarball): $ git clone -b thond/riscv-dev https://gitlab.com/cip-project/cip-core/isar-cip-core $ cd isar-cip-core $ wget https://raw.githubusercontent.com/siemens/kas/3.0.2/kas-container $ chmod a+x kas-container $ ./kas-container build kas-cip.yml:kas/board/qemu-riscv64.yml:kas/opt/sid-ports.yml:kas/opt/debian-kernel.yml then you can see the rootfs tarball at: build/tmp/deploy/images/qemu-riscv64/cip-core-image-cip-core-sid-ports-qemu-riscv64.tar.gz By the latest CI, the rootfs image (tarball) was uploaded to S3: https://gitlab.com/cip-project/cip-core/isar-cip-core/-/jobs/2702654409#L1586 Please let me know if you need more information. Best regards, Kazu

Hello Pavel,
then you can see the rootfs tarball at:Sorry, it seems the image is generated as .ext4 by default: build/tmp/deploy/images/qemu-riscv64/cip-core-image-cip-core-sid-ports-qemu-riscv64.ext4 My understanding is debian ports only provides packages for sid/experimental suitesUnfortunately, I can't get debootstrap --second-stage to work (I get so there is no package provided as stable/testing. http://ftp.ports.debian.org/debian-ports/dists/ Best regards, Kazu -----Original Message-----

As another suggestion, I've put the riscv64 debian rootfs image below. https://people.debian.org/~iwamatsu/riscv64-unstable-base.tar.gz Please feel free to use. Best regards, Nobuhiro 2022年8月18日(木) 14:04 Kazuhiro Hayashi <kazuhiro3.hayashi@...>:

Hello Pavel,
Apologies for the slow reply, I've been away. From: Pavel Machek <pavel@...>Renesas' official BSP (v1.0) is Yocto/Poky based and is available on their website: https://www.renesas.com/us/en/products/microcontrollers-microprocessors/rz-mpus/rzfive-risc-v-general-purpose-microprocessors-risc-v-cpu-core-andes-ax45mp-single-10-ghz-2ch-gigabit-ethernet But it's in source code form, so it would need building as per the included documentation. This document describes the build process for the Yocto BSP: https://www.renesas.com/us/en/document/mas/release-note-rzfive-board-support-package-v10 We'll have to work out with CIP how we want to support CIP-Core on the RZ/Five, given the current lack of official risc-v support in Debian. Something we can discuss in next week's extended TSC. Kind regards, Chris
