bmaptool is a command-line utility for creating block map files and using them to copy or flash raw disk images efficiently.
It’s designed for embedded Linux and image deployment workflows, letting you work with sparse images in a way that is faster and more reliable than traditional byte-for-byte copying tools such as dd.
This is free and open source software.
Key Features
- Creates block map files for image files.
- Copies images to files or flashes them directly to block devices.
- Can read images directly from a remote server.
- Supports flashing compressed images with on-the-fly decompression.
- Verifies SHA256 checksums while writing image data.
- Automatically verifies OpenPGP signatures for signed bmap files.
- Includes protection mechanisms to help avoid writing to mounted block devices.
