@mingzhangqun This is the problem on why it doesn't work and there are two ways to solve it - during next week.
Summary
Build Standard Support Images fails at step 10 — Prepare Info JSON and Matrices for the recomputer-rk3576-devkit chunk. The board's 4 variants are dumped in parallel, and each config-dump-json dies with a git exit 128 on a safe.directory write. The empty output can't be parsed → the whole matrix step fails, failing the build.

Root cause — concurrent git config --global race on ~/.gitconfig
- Only this board enables
seeed-extension. extensions/seeed-extension.sh runs a network fetch_from_repo (clones Seeed-Studio/seeed_armbian_extension) during the config phase, so it executes even under config-dump-json.
fetch_from_repo → git_ensure_safe_directory() (lib/functions/general/git.sh) does an un-serialized git config --global --add safe.directory <same path>.info-gatherer-image.py runs the 4 variants concurrently (512-worker pool). Multiple processes write ~/.gitconfig at once; git locks the file (.gitconfig.lock) and the loser exits 128 → empty JSON → matrix generation aborts.
It is a race, triggered only by the Seeed board because its extension clones a repo during config. A plain re-run may pass or fail depending on who wins the lock.
Suggested fix (in armbian/build)
- Preferred — serialize the global write: wrap the
regular_git config --global --add safe.directory in git_ensure_safe_directory() with an flock, so parallel workers can't collide. Fixes it for any source/extension under parallel config-dump-json, not just Seeed.
- Alternative — no network in config: make
seeed-extension.sh skip the fetch_from_repo during config-dump-json (defer the clone to the actual build) so the info step is side-effect-free.
Benign, not the cause
