bmap-writer is a command-line utility designed to efficiently write disk images to storage devices using block mapping (BMAP). It serves as a lightweight alternative to the Yocto BMAP tool, specifically for embedded systems. Unlike the Yocto BMAP tool, bmap-writer is C++ based does not require Python and focuses solely on writing an image.

• Alternative to Yocto BMAP Tool: Provides a lightweight alternative specifically for embedded systems.
• No Python Required: Does not require Python, making it easier to integrate into various environments.
• Support for Compressed Images: Handles gzip and xz compressed images, decompressing them on-the-fly during the writing process.
• Checksum Verification: Ensures data integrity by verifying checksums for each block.
• Efficient Writing: Writes only the necessary blocks, reducing the overall write time and wear on storage devices.

1. Generate a BMAP File: Create a BMAP file for your disk image using bmaptool.
2. Write the Image: Use bmap-writer to write the image to your target device, specifying the BMAP file for efficient block mapping.
