nRF5340 device crash when we send DFU reset command (./mcumgr --conntype ble --connstring ctlr_name=hci0,peer_name='XXXX' reset)

[Kaushik Parsana]

Dear Nordic,

I'm developing a software with the nRF Connect SDK v2.4.1. This software runs Matter on the nRF5340.

During performing DFU(Based on SMP service),I need to reset the MCU from mobile app after transmitting the nordic image and confirm nordic image.

We are sending this command(sudo ./mcumgr --conntype ble --connstring ctlr_name=hci0,peer_name='XXXX' reset) to reset nordic device, 

this process working fine since last one year, but now I wanted to send feedback that nRF5340 has received reset command and wanted to send some message over BLE to moble app, so iI have enable the reset callback by using below config.

CONFIG_MCUMGR_GRP_OS_RESET_HOOK=y

CONFIG_MCUMGR_GRP_OS_RESET_MS=500

After that I am getting callback as well and inside that I am verifying the few things and sending BLE message to mobile app and after that nRF5340 device resettled.

But this makes the OS crash with the following trace. 

uart:~$ E: IPC endpoint bind timed out

Is there any way to resolve this issue?

Hi, 

The log said "ASSERTION FAIL @ WEST_TOPDIR/zephyr/drivers/ieee802154/ieee802154_nrf5.c:1244"

You can check the code. 

If you convert the decimal numbers to hex, specifically the contents of LR and PC, you should be able to do a lookup of the addresses using arm-none-eabi-addr2line:

arm-none-eabi-addr2line -e my-build-folder\zephyr\zephyr.elf 0x000354fb

arm-none-eabi-addr2line -e my-build-folder\zephyr\zephyr.elf 0x00085e90

Could you post the output of the above?

Hi 

This is the output of that command.

Hi, 

You might be encountering errata 161 ([161] RESET: Network core is not fully reset after Force-OFF). Workaround was implemented in v2.5.0. 

Could you try v2.5.0?
