Power Fail-safe File Systems for eMMC Flash with Advanced Test Verification

Embedded developers can rapidly design eMMC-based applications with guaranteed data integrity

Embedded World, Nürnberg, Germany, 24 Feb 2015: HCC Embedded introduces fail-safe file system support for eMMC Flash that simplifies software integration and guarantees the integrity of data. HCC Embedded’s range of eMMC drivers supports high-performance file operations, fail-safe operations and secure erase. Devices with JEDEC eMMC 4.4, 5.0 and later interfaces (JESD84-B50) are supported. All file systems are supplied with an advanced test suite to verify correct operation.

eMMC Flash storage is designed to meet high performance and security requirements of deeply embedded systems in devices such as smart phones, point of sale terminals, industrial controllers, etc. The built-in NAND controller enables eMMC to be connected to any processor with a compatible memory interface such as MMC/SDIO. eMMC handles bad-block management, wear leveling, and error correction (ECC), greatly simplifying system design. HCC’s file systems utilize eMMC features such as a guaranteed ‘reliable write’ feature and configurable control of sudden power loss to help create a reliable system.

In addition to expanding the file system support for eMMC applications, HCC has adopted a rigorous validation process that uses custom test hardware with a verification suite for exercising file systems with eMMC devices. Developers can use the test suite to induce hardware errors and unexpected resets to verify fail-safe behavior and recovery. HCC will demonstrate a full system at Embedded World 2015 in Nürnberg, 24 – 26 February, in Hall 4, Stand 104.

“Genuinely reliable systems require each layer of the design to specify the level of service it requires. HCC has gone the extra mile to provide this and developers can now include verifiably reliable components to manage their eMMC-based applications,” said HCC Embedded CEO Dave Hughes.

HCC offers PCBs for BGA eMMC chips

To further aid the test and validation process for customers, HCC Embedded has developed a range of printed circuit boards to mount ball grid array (BGA) eMMC chips. These boards can then be plugged into a wide range of standard development board sockets such as MMC/SD interfaces, as well as HCC’s eMMC test and verification platform, thereby eliminating the expense of acquiring pre-installed eMMC boards. Developers may request sample boards directly from the HCC Embedded sales team.
