microej_official · March 18, 2026, 10:39am

Hello everyone,

The Abstraction Layer Kernel Flash version v2.0.0 has been released on GitHub!

The Kernel Flash Abstraction Layer implements the natives required by the Core Engine extension, the Kernel & Feature (KF). This enables sandboxed applications to be installed on top of a kernel in a flash memory, see Feature Installation section for more information.

This version refactors the flash_controller.h layer, requiring fewer functions to be implemented by the user.
Dispensable configuration macros have been removed, and the code has been simplified to improve readability.
The RAM allocation algorithm has been fixed.
The documentation has been improved to provide an accurate description of the implemented allocation algorithm.

See the CHANGELOG for more information:
