# JNDM123 PetaLinux Project

This repository tracks the source-level definition of the `JNDM123` PetaLinux
project in a form that is small enough to push to Gitee.

## Known-Good Stage Baseline

- Baseline date: `2026-04-20`
- Status: RM65 boots normally and automatically returns to bridge mode
- Important board-side path: keep the `rm65-init` and `rm65-serial-bridge`
  startup logic that uses `/dev/ttyUL1` to recover RM65 bridge mode
- Related `myiot` source baseline: commit `abc7c9e`

## What Is Tracked

- `project-spec/`
- `components/`
- `config.project`
- `.petalinux/metadata`
- helper scripts needed to rebuild or maintain the project

## What Is Not Tracked

- `build/` cache and downloads
- `images/` generated boot and rootfs artifacts
- `.Xil/` and other generated tool output
- local backup directories, logs, PDFs, and scratch experiments

## Rebuild

```bash
cd /home/ph/work/proj/JNDM123
source /opt/pkg/petalinux/2019.1/settings.sh
petalinux-build
```

## Notes

- The generated images are intentionally excluded because they exceed practical
  Git/Gitee limits and should be archived separately as stage snapshots.
- If the `myiot-runtime.tar.gz` payload changes often, consider moving it to a
  release artifact store or Git LFS in the future to avoid repository growth.
