I'm having a hard time getting nrfjprog to remain in my PATH env variable when using the Toolchain manager. I am following this post -- I am able to `echo` my PATH variable after my export command. However, whenever I close down the terminal and use the Toolchain manager to open up the terminal again, all of my PATH variables from before (nrfjprog and mergehex) are gone. Also, all of my system PATH variables don't exist in this terminal window that was opened from the Toolchain manager. If I echo PATH in a fresh terminal window (opened from spotlight) my list is much different than what I see when I echo PATH in the terminal opened from the Toolchain manager. What am I missing here? I don't want to export new PATH variables every time I want to flash my Zephyr project.
