StrongARM 110 Evaluation Board Firmware

Rear view of the SA 110 Evaluation Board

This board has both Cyclone and ABLE available. Cyclone is no longer developed and new users should use ABLE in preference. Users may switch between either firmware as required. ABLE supports more features than Cyclone so functionality may be lost during a downgrade.


ABLE is Simtec's advanced board firmware and bootloader. It is cross platform and is being actively developed for all Simtec boards.

The EB110ATX board is equipped with NOR based flash which is used to boot ABLE.

The current version of ABLE for the EB110ATX is 2.55. The changelog details the changes in this release. Before upgrading please ensure any changes are suitable for your requirements. Simtec try to ensure there are no regressions from release to release, however it is up to the user to ensure that there are no known issues with a given release which may adversely affect them. This must be done prior to upgrading a board as, if the upgrade fails, the board may be left in a state where booting is not possible.

An upgrade image is provided to allow a cyclone bootloader based system to be updated to ABLE. This upgrade updates to version 2.21 of ABLE, an additional upgrade to the latest version of ABLE will then be required.

Several tools are available which provide extra functionality not built into ABLE. These tools and their documentation are available from the ABLE resources section.
