SDB-1.1 is a compatible upgrade of SDB-1.0. It adds two informative records, thanks to Matthieu Cattin, and includes some rewording and clarification (especially about absence of interrupts).

The repository also includes sdbfs, which was born as a separate project. Such filesystem is already being used in our FMC flash memories, based on the user-space tools included in this package.

You can find the specification in the document section (Document)
