MPU6050_DMP6 always throws exception when run in wemos D1 Mini or NodeMCU
Hi! I tried to use the MPU6050_DMP6 in the arduino mega, and it works perfetcly. But when I tried to use in the wemos D1 mini, or even in NodeMCU, it always throws an exception. I used the code as is, only change the interrupt pin to D5 or D6.
The error:
User exception (panic/abort/assert)
--------------- CUT HERE FOR EXCEPTION DECODER ---------------

There's a way to run in this MCU's?
Looking at the stack trace and that you get into an abort in __attachInterruptFunctionalArg, you can get into an abort call if you or a library is using attachInterrupt but the target function wasn't placed in instruction RAM (IRAM), which is mandatory for interrupt service routines.

What's the exact code you're running?
HI!
I'm running the example code:

NOTE: In addition to connection 3.3v, GND, SDA, and SCL, this sketch

digital I/O pin 2.

NOTE: Arduino v1.0.1 with the Leonardo board generates a compile error
when using Serial.write(buf, len). The Teapot output uses this method.
The solution requires a modification to the Arduino USBAPI.h file, which
is fortunately simple, but annoying. This will be fixed in the next IDE
release. For more info, see these links:
