Helium’s file splitting, checksums, and fill operations are perfect for padding to exact flash sector sizes. Its cross-platform nature means you can use the same tool on Windows (to run vendor tools) and Linux (for build scripts). One of the common pain points with hex

A good hex editor must be accurate, fast, and capable of handling huge files. This is where Helium excels.
