This should be so simple…
I’m running 1.39 of Particle CLI
Just reinstalled Particle workbench
Configure my workspace for 0.9.0
Clean App and Device OS
When I go to recompile, I get an error:
…/third_party/nrf5_sdk/nrf5_sdk/modules/nrfx/mdk/nrf52840.h:152:130: fatal error: core_cm4.h: No such file or directory, but it works fine with 0.8.0-rc27.
What could I possibly have done wrong with such a simple set of steps??
