Hello,
I am running BT together with MPSL timeslot. When timeslot ends and RADIO and TIMER10 are cleaned up and a new timeslot is requested I get following HARD FAULT:
[00:00:05.087,909] <err> mpsl_init: MPSL ASSERT: 2, 62 [00:00:05.088,079] <err> os: ***** HARD FAULT ***** [00:00:05.088,217] <err> os: Fault escalation (see below) [00:00:05.088,365] <err> os: ARCH_EXCEPT with reason 3 [00:00:05.088,525] <err> os: r0/a1: 0x00000003 r1/a2: 0x200046df r2/a3: 0x00000000 [00:00:05.088,736] <err> os: r3/a4: 0x00000003 r12/ip: 0x0000177e r14/lr: 0x0001e633 [00:00:05.088,941] <err> os: xpsr: 0x0900009a [00:00:05.089,102] <err> os: s[ 0]: 0x00000000 s[ 1]: 0x00000000 s[ 2]: 0x0002cdcd s[ 3]: 0x20005cbc [00:00:05.089,379] <err> os: s[ 4]: 0x0000003e s[ 5]: 0x000133d9 s[ 6]: 0x00000000 s[ 7]: 0x0000e5a5 [00:00:05.089,652] <err> os: s[ 8]: 0x00000002 s[ 9]: 0x00000032 s[10]: 0x200017b0 s[11]: 0x00000020 [00:00:05.089,928] <err> os: s[12]: 0x200027d0 s[13]: 0x0000d1a1 s[14]: 0x200027d0 s[15]: 0x00026079 [00:00:05.090,202] <err> os: fpscr: 0x20005ce0 [00:00:05.090,352] <err> os: Faulting instruction address (r15/pc): 0x00019da0 [00:00:05.090,536] <err> os: >>> ZEPHYR FATAL ERROR 3: Kernel oops on CPU 0 [00:00:05.090,718] <err> os: Fault during interrupt handling [00:00:05.090,870] <err> os: Current thread: 0x20002a10 (unknown) [00:00:05.091,040] <err> os: Halting system
What could be the reason of this hardfault and/or what could it mean?
