I had trouble starting over because “.zephyrtools” would not let me delete some of it’s files. I tried all sorts of things (a reinstall failed would fail with a lstat error).
I found I could rename the old folder, like .zephyrtoolsOLD. Then I was able to reinstall to “.zephyrtools” and get it working.
Zephyr Setup : newtmr didn’t make the connection string.
It seems newtmgr does not work with Windows? I can do the COM setting, but maybe not the baud rate?
