.BIN files in sys directory - do they belong

  • Hi,

    I recently updated a spare Duet WiFi board that was running an older v2 firmware to a more recent v2 firmware (2.05.1 is what I had on on hand).

    When finished everything seems to be working fine but there are three .BIN files in the SYS directory.


    Should they be there? I don't recall .BIN files being left there on past updates BUT my memory is not what it once was.

    They are harmless. If you ever needed to reflash for some reason they would be present. The IAP files are needed for flashing.

    You need iap4e.bin when you upgrade the main firmware. The other two .bin files are the current main firmware and current wifi firmware.

  • Thanks for the feedback.
