config BR2_PACKAGE_BMAP_TOOLS bool "bmap-tools" depends on BR2_PACKAGE_PYTHON3 select BR2_PACKAGE_PYTHON3_PYEXPAT # runtime select BR2_PACKAGE_PYTHON_SETUPTOOLS # runtime, pkg_resources select BR2_PACKAGE_PYTHON_SIX # runtime help Tool to flash image files to block devices using the block map bmaptool is a generic tool for creating the block map (bmap) for a file, and copying files using the block map. The idea is that large file containing unused blocks, like raw system image files, can be copied or flashed a lot faster with bmaptool than with traditional tools like "dd" or "cp". Relevant optional dependencies: - Busybox compiled with CONFIG_BZIP2, or BR2_PACKAGE_BZIP2, to support bz2 compressed images - BR2_PACKAGE_PIGZ for optimized gzip decompression - Busybox compiled with CONFIG_LZOP, or BR2_PACKAGE_LZOP, to support lzo compressed images. - BR2_PACKAGE_ZIP to support zip compressed images - BR2_PACKAGE_LZ4 to support lz4 compressed images - BR2_PACKAGE_ZSTD to support zstd compressed images - Busybox compiled CONFIG_FEATURE_SEAMLESS_* or BR2_PACKAGE_TAR to support tar compressed images - BR2_PACKAGE_OPENSSH to retrieve images over SSH. - BR2_PACKAGE_SSHPASS to retrieve images over SSH if password authentication is used. Image signature verification is not supported as python-gpgme is not available. Optimized bzip2 decompression is not supported as pbzip2 is not available. https://github.com/yoctoproject/bmaptool
