The problem U-Boot’s pytest suite runs hundreds of tests in a single sandbox session. Each test sends commands to a long-running U-Boot process, so state left behind by one test can break those that follow. CI runs all tests in collection order and that is the only configuration known to work. When tests are run…
We’ve been using Claude Code for U-Boot development and it’s genuinely useful — writing tests, debugging driver issues, working through refactoring. But running an AI with full access to my dev machine makes one…nervous. So we added a cc subcommand to uman, a tool for managing common U-Boot development tasks, that runs Claude Code inside an LXC container….
If you maintain patches against more than one U-Boot tree (or another project), you have probably wished that patman could remember which mailing list, SMTP identity and patchwork server to use for each one. A new 32-patch series adds exactly that: first-class support for multiple upstreams, each with its own send settings and patchwork integration….
Pickman automates cherry-picking commits from upstream U-Boot into a downstream branch, packaging each batch as a GitLab merge request. Until now, when a CI pipeline failed on one of those MRs — a build error caused by a missing context change, a renamed symbol — a human had to read the logs, find the problem,…
U-Boot’s CI pipeline has seen two rounds of improvements recently, adding test coverage for new platforms, the Rust ulib demo and EFI application boards. Rust Toolchain and Ulib Demo Testing The first round added the Rust toolchain to the Docker CI image and enabled testing of the ulib Rust demo across multiple architectures. The demo…
Linux needs deep understanding of the hardware it is running on. Without this it either cannot function, or cannot take full advantage of hardware features. While most peripherals can be probed to find out what they are (SCSI, USB, UFS, etc.), we need a way to know about the core hardware, such as the USB…
One of the more ambitious initiatives in U-Boot recently is the U-Boot Library (ulib) — the ability to build U-Boot as a reusable library that external programs can link against. Until now, ulib has only worked on sandbox, U-Boot’s native host execution environment. This series takes the first step toward real hardware by bringing ulib examples to…
U-Boot has long supported extlinux-style boot configurations, but there is another widely-used standard for describing boot entries: the Boot Loader Specification (BLS). Fedora, RHEL and other distributions use BLS Type #1 entries to describe available kernels and their parameters. With this series, U-Boot gains native support for discovering and booting from these entries. Why BLS? The extlinux format…
Introduction Pickman is a tool for cherry-picking patches from upstream U-Boot into a downstream branch. It walks the first-parent chain of the source branch, finds merge commits, and cherry-picks their contents one merge at a time using an AI agent. This works well for normal merges containing a handful of commits. But upstream U-Boot occasionally…
Introduction U-Boot on x86_64 has traditionally relied on a Secondary Program Loader (SPL) to bootstrap into 64-bit mode. SPL starts in 16-bit real mode (as required by the x86 reset vector), transitions through 32-bit protected mode, sets up page tables, and finally jumps into the 64-bit U-Boot proper. A recent series adds support for running…
