Simplifying rapid production programming of SD cards and eMMC

SEGGER’s FAT Image Creator is a production utility that prepares a FAT file system for rapidly programming embedded or removable media in production.

The FAT Image Creator constructs a complete file system while keeping the images as small as possible. By storing only relevant data inside the image, production programming time is minimal. A typical image of a size of 20MB can be programmed in a few seconds.

“The FAT Image Creator makes programming eMMC and other storage cards more efficient,” says Dirk Akemann, marketing manager at SEGGER. “Having just one file to work with, which includes multiple files and the directory structure, minimises production to a single write operation. This significantly reduces the risk of errors and greatly increases programming speed.”

Because the solution is a command line tool, it easily integrates into a CI/CD process, removing all human interaction and automatically creating up-to-date production images.

Files can be added as required, and directories can be readily created. The tool can create a complete image (BIN file) or a condensed image containing only relevant sectors (Motorola S-record or MOT).

The utility ships executable for the Windows, macOS, and Linux operating systems.
