Hi,

We are using MQX 5.1 running on NXP i.MX7S ARM Cortex-A7 core. I got an unhandled interrupt which crashed my initialization task. Here is the interrupt information from MQX unexpected interrupt handler:

*** UNHANDLED INTERRUPT ***
Vector #: 0xfffffff1 Task Id : 0x20003 Td_ptr 0x801c3ea0
PC: 0x801c0558 LR: 0x801c0558 SP: 0x801c0558

Memory dump:
0x801c0558 : 0x801c0558 0x801c0558 0x801c0558 0x801c0558
0x801c0568 : 0x00000003 0x31002000 0x801d2fc0 0xffffc0ff
0x801c0578 : 0x00000000 0x00000000 0x00000000 0x80007c1c
0x801c0588 : 0x801bf000 0x00000001 0xa000019b 0x00000001
0x801c0598 : 0x00000000 0x000000a0 0xe5ba32c8 0x801bf870
0x801c05a8 : 0x00000018 0x000000f0 0xe59ff018 0xe59ff018
0x801c05b8 : 0x00000003 0x801d2fc0 0x801d2fc0 0xffffc0ff
0x801c05c8 : 0x00000000 0x00000000 0x00000000 0x00000000

Looking at the map file, PC/LR/SP all point to a location in KERNAL_DATA section:

Execution Region KERNEL_DATA (Base: 0x801bf000, Size: 0x00800000, Max: 0x00800000, ABSOLUTE)

Base Addr Size Type Attr Idx E Section Name Object

0x801bf000 0x00800000 Zero RW 2 KERNEL_DATA.bss anon$$obj.o

I am basically clueless. Any ideas?
