Add SpacemiT K3 Vendor BSP by threexc · Pull Request #636 · riscv/meta-riscv

Trevor Gamblin (threexc) · 2026-05-21T12:06:23Z

Overview

This is an effort on behalf of SpacemiT to add support for their K3 platforms to meta-riscv. It breaks down the changes made in the spacemit-yocto fork of meta-riscv into more discrete and digestible pieces focused on a minimal, headless image, while omitting the parts which aren't strictly required, notably:

Other boards (will be added on a case-by-case basis, as people can test them)
Custom toolchain usage for firmware blobs
Changes to the mesa recipes and related graphics support
Support for the SpacemiT Titan flashing process

These features will be investigated after basic support is tested and merged.

I've opened this now so that others can review and propose additional BSP support if they have other K3 boards to test with. I've followed the same format we did for the K1 platforms and created a k3-vendor.inc file with the common logic included so that adding those other BSPs as we go will require minimal effort.

Status

As of EOD on May 29th, 2026, I have confirmed that this works by booting three ways:

kernel + dtb + Bianbu rootfs (from UFS):

Secondary booting from NVMe rootfs. This is a slightly more complicated process. Here are the steps I followed:
1. Writing the .wic image to my NVMe drive with a USB-to-NVMe adapter and bmaptool
2. Breaking into the UFS U-Boot and running:

I'll test an NFS root soon. Do you all think that this combination is sufficient proof that the BSP is ready? It would be good to confirm this also with a CoM260 and microSD card, but I'm not sure how soon I'll be able to try that. Is there someone else out there who's expecting a CoM260 board any day now?

Note that most of the commits have been updated to fix attribution - Yingjie Liu is the correct author for almost all of the commits (excepting the u-boot-spl-k3 patch), and I have added my Co-developed-by tag.

See also: #635

June 8th, 2026 Update: We have confirmed that NVMe flash and boot works. Here is the console output from Yingjie's testing:

how is this related to #635 ? Can you consolidate both PRs, I do not want multiple PRs addressing same patches.

Trevor Gamblin (threexc) · 2026-05-21T14:53:24Z

how is this related to #635 ? Can you consolidate both PRs, I do not want multiple PRs addressing same patches.

This is my effort to break down what's in #635 into more reviewable chunks and clean it up - I had started yesterday but hadn't sent a PR yet before that one went up. I will discuss with the submitter and we'll get it down to one or the other soon.

Trevor Gamblin (threexc) · 2026-05-21T20:10:41Z

Latest push builds OK, but has some warnings and a lot of unnecessary stuff. Still need to do a sweep of licensing info, fix attribution (waiting for SpacemiT feedback), and summarize all of the differences.

My K3 was scheduled to arrive today, but it isn't here. Will start testing as soon as it arrives.

Trevor Gamblin (threexc) · 2026-05-22T02:04:45Z

Pushed some more cleanups to break the branch down to a basic image for SD card flashing only. From here on out I will start cleanups like what Alistair Francis (@alistair23) has suggested.

Trevor Gamblin (threexc) · 2026-05-22T19:59:05Z

Getting there. Still some problems I'm tweaking in the U-Boot recipe, plus the outstanding review comments. Aiming to have something functional for the Monday or Tuesday timeframe.

Thanks for the feedback so far!

Trevor Gamblin (threexc) · 2026-05-22T22:31:17Z

With my latest push, U-Boot is also building OK - I reworked it after reviewing what the vendor BSP for the OrangePi boards was doing.

Still have a few outstanding review comments to address, followed by device testing when it's here.

I'm able to tftpboot my kernel + dtb OK on a K3 Pico-ITX, using the existing rootfs:

The binaries are under a simple copyright in the spacemit-firmware repository rather than an open-source license, so mark the recipe license as 'CLOSED' with a note about why.
