1️⃣ Create package/helloworld directory
2️⃣ Write Config.in + helloworld.mk (case-sensitive!)
3️⃣ Enable in sun8iw11p1_hf_defconfig
4️⃣ make menuconfig → compile → pack

💡 Key Insights:

.mk scripts glue Buildroot’s build system to your app’s Makefile
Error Alert: Directly overwriting .config breaks builds! Use savedefconfig instead
Final binary lands in /bin post-compilation 📦
