Hello,
first, thank you for your hard work it's a pleasure to use Arduino for the ESP8266.
I was using the staging version 2.1.0 rc2 installed from board manager, with a NodeMCU 0.9 board.
This morning I noticed there was a stable version for 2.1.0 so I changed the link for additionnal boards in preferences, downloaded version 2.1.0 in board manager and restarted arduino.
Then, I tried to run the sketch that was running perfectly some minutes ago with the rc2 version and it was looping with a fatal error in the serial window. I disconnected everything from the board, I tried simple sketches like blink and even BareMinimum, and I always have the same result in the serial window (I tried every possible combination of programming/spiff setting at 80 or 160MHz), uploaded at 57600 only,...)
Fatal exception (28):
epc1=0x402066d4, epc2=0x00000000, epc3=0x00000000, excvaddr=0x00000001, depc=0x00000000

If I try to select stable version 2.0.0, I can run a sketch.
If I switch to staging version and put 2.1.0 rc2 or 2.1.0 rc1 I can run a sketch.
