+# ARM64 Linux Binary Build Scripts
+
+This directory contains the build system for cross-compiling STM32 upload tools for ARM64 (aarch64) Linux platforms.
+
+## Overview
+
+These scripts use Docker to cross-compile the following binaries from x86_64 to ARM64:
+
+- **dfu-util** - Device Firmware Update utility
+- **dfu-prefix** - DFU file prefix tool
+- **dfu-suffix** - DFU file suffix tool
+- **hid-flash** - HID bootloader flash utility
+- **upload_reset** - STM32 reset utility
+
+## Prerequisites
+
+- Docker installed and running
+- Sufficient disk space (~2GB for build)
+
+## Quick Start
+
+From the repository root directory:
+
+```bash
+./src/linux-aarch64/build.sh
+```
+
+This will:
+
+1. Build and run ARM64 test stage (validates binaries work via QEMU on x86_64)
+2. Build Docker image with the ARM64 cross-compilation toolchain
+3. Compile all required binaries for ARM64
+4. Extract the binaries to `linux/aarch64/`
+5. Set executable permissions
+6. Verify binary architecture
+7. Clean up the Docker container
+
+## Build Script Details
+
+### `build.sh`
+
+Main build orchestration script that performs the complete build and test workflow.
+
+**What it does:**
+
+1. **Validates prerequisites** - Checks Docker is installed and running
+2. **Builds test stage** - Uses `docker buildx build --platform linux/arm64 --target test`
+   - Cross-compiles binaries for ARM64
+   - Tests all binaries on ARM64 (uses QEMU emulation on x86_64)
+   - Ensures binaries actually execute correctly
+   - Build fails if any binary doesn't work
+3. **Builds export stage** - Uses `docker build` to create final image
+4. **Extracts binaries** - Copies binaries from container to `linux/aarch64/`
+5. **Sets permissions** - Makes all binaries executable
+6. **Verifies output** - Runs `file` command to confirm ARM64 architecture
+
+### `clean.sh`
+
+Removes all built ARM64 binaries from the `linux/aarch64/` directory.
+
+### `Dockerfile`
+
+Multi-stage Docker build with integrated testing.
