Hello George,
Development expert said
“the resource is very limited in FRDM-KE04Z, so all of our SDK examples cannot even succeed build for MCUXpresso IDE. So, FRDM-KE04Z does not support MCUXpresso IDE.”
I checked other toolchain SDK package, for example KDS, IAR or MDK, they includes demo code,
I think you can create a new proejct on MCUXpresso IDE, then refer to the demo code on other IDEs.

Hope it helps
Have a great day,
TIC
