Monheim am Rhein, Germany — December 10, 2025
SEGGER’s Storage Image Creator FAT now supports the exFAT file system in addition to FAT. This update expands the range of storage configurations that can be prepared for embedded devices that use eMMC memories or SD cards. It also strengthens SEGGER’s toolchain for efficient preparation of file-system images in production.
With the new exFAT capability, manufacturers can create images for larger and more flexible file systems that are widely used in modern embedded products. Storage Image Creator FAT generates a single image that contains only the sectors required for programming. This keeps image size small, shortens transfer time and ensures consistent results, which is especially valuable in production environments.
A key application is the preparation of eMMC and SD-card content directly on the production line. In combination with SEGGER’s Flasher in-system programmers, the tool enables fast and automated programming of FAT and exFAT file systems. It can be integrated into CI and CD pipelines, allowing up-to-date images to be generated and deployed without manual steps.
“Given the increasing storage capacities, adding exFAT support to the Storage Image Creator significantly enhances what our customers can accomplish in production,” says Dirk Akemann, Head of Technical Marketing at SEGGER. “When used with our Flasher series, the tool provides an efficient and reliable approach to in-system programming in high-throughput manufacturing environments.”
SEGGER Flashers support a wide range of microcontrollers, SoCs and external memory types. They now offer an even more versatile solution for preparing and programming FAT and exFAT file-system images during production.
