Build Types


This page refers to the last formal release of TomatoUSB Build 54 – dated 11/30/2010

TomatoUSB is currently developed only through community contributions in the form of several “mods”. Please see the mods page for more information.

This forum has no active administration, please go to where all currently active developers are available.

The Tomato USB comes in several different editions:

  • Standard: most basic features; ~300KB JFFS space (5 blocks) available on 4MB flash routers;
  • Extras: all features of Standard plus built-in NTFS support (starting from build 36), included Linux Ext2/Ext3 and FAT32 filesystem utilities (fdisk, e2fsck, mke2fs, mkswap, mkdosfs), built-in loop device support, some extra Linux commands not included in other builds, and additional color schemes. ~120KB JFFS space (2 blocks) available on 4MB flash. This version is for people who don’t really need JFFS space, or have 8+ MB flash routers, and would like to be able to partition/format drives in Linux native Ext2/Ext3 format or in FAT32 format directly on the router without installing any additional tools.
  • Lite: all features of Standard but no Samba; some very minor features are stripped out of Busybox, about 600KB JFFS space (10 blocks) available on 4MB flash routers;
  • No CIFS: all features of Standard but no CIFS Network filesystem support, about 420KB JFFS space (7 blocks) available on 4MB flash routers;
  • VPN: Extras edition merged with SgtPepperKSU’ VPN build with Web GUI (no JFFS space left on 4MB flash).
  • No USB: Initially this was the USB mod… However, it grew up to be an “extended” version of Tomato even without USB support, so starting from build 36 Tomato USB includes non-USB edition (ND only) for routers with no USB ports. This build has about 900KB of JFFS space (15 blocks) available on 4MB flash routers.

Detailed matrix of features present in different editions.


Since January 2010, Tomato USB also supports Kernel 2.6, in addition to the stable Kernel 2.4 builds. The K26 support is required for newer routers where Broadcom never released a 2.4 wifi driver. For older routers, you can choose between the K24 builds or the K26 builds.

K26 builds are of two different types: MIPSR2 builds (for newer CPUs) and MIPSR1 (for older CPUs). You must download the correct version given your router.

Naming convention

Tomato USB firmware builds are named according to the following specification:

  • <VER> – Tomato base version (i.e. 1.27)
  • <ND|K26|[Model]> – indicates the platform:
    • ND – Tomato ND (“new driver”) builds based on kernel 2.4
    • K26 – Tomato builds based on kernel 2.6 (assumes ND)
    • [Model] – Special Tomato builds for certain router models
  • [USB] – optional indicator of built-in USB support
  • <NNNN> – build number, i.e. 9043
  • <MIPSR2|MIPSR1> – architecture:
    • MIPSR2 is for MIPS32 Release 2 CPUs
    • MIPSR1 is for all other MIPS CPUs (MIPS32 Release 1)
    • Kernel 2.4-based builds are always MIPSR1, and currently are not compatible with MIPSR2 routers
  • [-subver] – optional subversion number, e.g. -beta
  • [EDITION] – the build edition, e.g. Ext (Extras), VPN (OpenVPN) etc.

The table above only includes models that have been reported to work properly with Tomato USB. Most of the other models supported by Tomato kernel 2.4 builds should be compatible with kernel 2.6 builds as well but have not been tested yet. The E4200 5GHz wireless is as yet unsupported (Sept 2011).
