Partitioning is supported on most CableFree device type devices (but note it is not supported on x86). Please check for more details on device support.

Starting from v6rc5 it is possible to partition NAND flash, allowing to install own OS on each partition and specify primary and fallback partitions.

If a partition should fail for some reason (failed upgrade, problematic configuration introduced, software problem), the next partition will boot instead. This can be used as an interactive backup where you keep a verified working installation, and upgrade only some secondary partition. If you upgrade your configuration, and it prooves to be good, you can use the "save config" button to copy it over to other partititions.


Note: Repartitioning of the NAND requires latest bootloader version


Warning: Downgrade to v5 is not possibie if multiple partitions have been created. First revert to a one partition setup, only then downgrade

Minimum partition sizes:

  • 32MB on MIPS
  • 40MB on PowerPC
  • 48MB on CCR

Maximum number of allowed partitions is 8.
