MCUBOOT SMP FAULT

[CreativeIndustryAg]

Hello
Project in C++.

I'm trying to use mcumgr and application always crash (except first call "image list')
./mcumgr --conntype udp --connstring=[192.168.1.225]:1337 image list

After first call abowe i get:
Images: image=0 slot=0 version: 1.0.0 bootable: true flags: active confirmed hash: d4b17095395ee0545ed57d6784f181bb2280ba9aec1068089533ab80292df33a Split status: N/A (0)

So it works, but every next call or call any other mcumgr function crashes system:
[00:00:16.101,501] <err> os: ***** BUS FAULT ***** [00:00:16.101,562] <err> os: Precise data bus error [00:00:16.101,562] <err> os: BFAR Address: 0xf001a8c0 [00:00:16.101,623] <err> os: r0/a1: 0xf001a8c0 r1/a2: 0x8003d608 r2/a3: 0x8003d60c [00:00:16.101,654] <err> os: r3/a4: 0x00000010 r12/ip: 0xffffffff r14/lr: 0x60050dbf [00:00:16.101,654] <err> os: xpsr: 0xa1000000 [00:00:16.101,684] <err> os: Faulting instruction address (r15/pc): 0x6003ebfc [00:00:16.101,715] <err> os: >>> ZEPHYR FATAL ERROR 0: CPU exception on CPU 0 [00:00:16.101,745] <err> os: Current thread: 0x80009ca0 (sysworkq) [00:00:16.150,390] <err> os: Halting system

I tough this is stack problem, so i increase every one and it looks like:

So it seems there is no stack problem.

DO you have any idea what is wrong?

I found bug in my application:
When DHCP set IP then it is required to reinitialize SMP.
