I’d like to develop using Arduino on the nrf52840 Feather Express. I created a new project using the wizard, that all seemed to go well. But when I try to build blinky, things become unhappy. Please see attached screen snaps. The entire log that is displayed is below. Any pointers wold be deeply appreciated!

^error,msg=”Don’t know how to run. Try \”help target\”.”Hi,
Looks like you are trying to use the GDB simulator that does not support your device. Generally, the built-in simulator is not usable for ARM targets and can only be used to verify that gdb is able to load the debugging symbols.
Please consider using one of the supported debug methods instead.
