Bootloader options in Apollo library 2.0.X on Mac

In the 2.0.X Apollo libraries in Arduino on a mac, the SVL is listed as out of order, it Bootloaders it says, “Sparkfun Variable Loader (Out of Order)” and also says “Ambiq Secure Bootloader (Recommended)”. I have tried using both without any success on a Reboard Artemis Nano. The SVL works with the 1.2.X libraries just fine, but I want to use the bluetooth so I need to use the 2.X libraries.

I need help knowing how to load my arduino sketches.

On this page https://learn.sparkfun.com/tutorials/de … rogramming, it says that you can use the Ambiq bootloader, but talks about having to have pin 47 high to use the Ambiq bootloader, but the Readboard Artemis Nano doesn’t have that many pins. Is there a way to get the Ambiq bootloader to work? I’m not sure how to get things loaded from Arduino with the 2.X libraries.
