In your sparkfun core directory:
c:/Users/YourName/AppData/Local/Ardino15/packages/SparkFun/hardware/apollo3/2.02/variants/SFE_ARTEMIS/variant.cpp

comment out UART Serial1(SERIAL1_TX, SERIAL1_RX); line.

That will fix the Serial problem – at least it did for the Nano.

The LED problem also happens with Edge2 board. Haven’t been able to get it’s LED’s to light either.

Thanks for your response. I commented out that line in "SFE_ARTEMIS/variant.cpp" and in "SFE_ARTEMIS_NANO/variant.cpp" both separately and in both files with no change in being able to get Serial communication back or get the LED to blink.

For reference I should have mentioned, I'm doing this on a Mac, and I'm using the "Sparkfun Variable Loader (Out of Order)" that is marked as out of order, but according to the Arduino IDE, it completes successfully. If I use the "Ambiq" bootloader it says it attempts upload 3 times and fails. I tried changing the Baud rate to all possible options and have no success.

I'm win10. Sparkfun Variable Loader will not work at all. Only Ambiq works. Also, I use a terminal emulator called Termite. It will not display anything or work at all unless the board has completed booting prior to connecting the serial. That's about all I know about this. Core needs a little work I think.

Same here.
As for svl, mine failed due to the Big Sur update bug but manual reconfiguration to enable svl.py fixed that (output below). I have yet to verify the BLE LED code is advertising though.
