Can you provide some details about your PC? W7, XP, Mac, etc?
I also (as you can read from the older posts) had issues getting connected and the firmware updated.
For W7/XP:
1. Follow the steps to update your drivers as described here:

2. Follow the steps to update the Martinez board here:

I went through #1 about 3 times. You can check if your drivers are correctly updated by going to Start --> Control Panel --> Device Manager and left click (once to expand) the selection (i.e. Universal Serial Bus controllers). RIGHT click the selection that you are wanting to check (i.e. USB Serial converter) and point your mouse to Properties and select the "Driver" tab. The 3rd item down reads "Driver Version". If you installed it correctly it should read 2.08.24. IF NOT, then you need to start over and follow the instructions again (like I had to!).
AFTER you confirm that the drivers for
both the "Ports" (COM port assigned to your gimbal) and the Universal Serial Bus Controllers ("USB Serial Converter" at the very bottom of the list) show the same driver 2.08.24 ... proceed to following the steps in the .pdf as linked to in #2 above.
For #2, critically important (in my case anyway) was following the instructions when installing the Arduino program. You MUST untick the "Install USB Driver" option!! If you didn't do this, uninstall and start over with #1 above.
Once done with the steps above, click the connect button the Arduino program after you connect the gimbal board to your PC via your USB cable. Make you r changes (I used the ones from Bengit in an earlier post in this thread) and when done editing, selected save, Load, Load to Flash.
Once all of that is done, you will need to set up your TX/RX to control the gimbal on whichever channel you select. I am using a Futaba MZ14 / S-Bus Rx and can help you through that but if you are using a Spectrum (or?) then someone else will need to help you through that channel assignment / setup.
Hope I didn't miss anything and that this helps?
Dale.
