  Hey all - after finally receiving my backordered FatShark goggles and having a jolly ol' time flying around, the need for an OSD has become quite apparent.  Luckily I had already purchased the MinimOSD a few months earlier.  I tried config'ing it but received what appears the be a common problem of not being able to speak to the bootloader.  I followed the information found here and here, checked this out and also this.

  I did see that I needed a FTDI cable to speak to the MinimOSD and upload a bootloader so good thing I already had this cable.

  However - still no go.  Would someone that has had success with this kindly let me in on something I may have missed via here or PM.

  Many thanks,
  David.

  Thanks Randy

  Your suggestion worked. I loaded AC2.9.1b to my APM1.4 and my Quad is back to flying.

  You aren't seriously thinking of flying without an R/C controller, are you?

  @Gireesh,

       On the mission planner's firmware screen you will see a Load Previous Firmware link on the bottom right.  After clicking the download select an entry that has "AC2.9.1b" at the end

  How I can get software version : 2.9.1 for APM 1.4. It is no longer supported.

  Depends on your software version: 2.9.1 - yes, 3.0.1 - no.
