Scary Messages on the Serial Console

CPU exceptions

CPU exception 6

Problem

Here's a message I encountered while trying to run the AIO.js sample:

***** CPU exception 6
Current thread ID = 0xa800ea60
Faulting segment:address = 0x00000008:0x40055e65
eax: 0xa4010156, ebx: 0xa800f2fd, ecx: 0x000000c1, edx: 0x0005a103
esi: 0xa800f134, edi: 0x00000000, ebp: 000000000, esp: 0xa800f0c8
eflags: 0x00010206
Fatal task error! Aborting task.

Solution

The problem turned out to be that I was using a new Arduino 101, where I had never flashed code onto the ARC partition. So I was able to resolve it with:

$ make arc dfu-arc

Note: when you use this command, you need to be ready to press the Arduino 101's Master Reset button at about this point in the output:

  LD      src/built-in.o
  AR      libzephyr.a
  LINK    zephyr.lnk
  SIDT    staticIdt.o
  LINK    zephyr.elf
  BIN     zephyr.bin

Otherwise, you will have to try make dfu-arc again just after you have reset the device.
