+# Yocto configuration for BeagleBone (esp-egycounter)
+
+This directory provides a Yocto setup that builds a BeagleBone image with:
+
+- Debian-style package management (`apt`, `dpkg`) via `package_deb`
+- No X server/UI stack
+- SSH (`openssh`), Python 3 (with stdlib modules), and `nginx`
+- USB client Ethernet gadget support (RNDIS/ECM style)
+- Kernel based on RobertCNelson `ti-linux-kernel-dev` configuration with added `qca7k` support
+- Integrated `battery-control` scripts from this repository
+- Included `pyPLC` and `OpenV2Gx`
+
+## Build quickstart (kas)
+
+From repository root:
+
+```bash
+cd yocto
+kas build kas-beaglebone.yml
+```
+
+The image target is `egycounter-image`.
+
+## Notes
+
+- `OpenV2Gx` is built as part of the Yocto build via the custom recipe.
+- `pyPLC` is installed to `/opt/pyplc`.
+- `battery-control` scripts are installed to `/opt/esp-egycounter/battery-control`.
