spi communication issue on nrf5340 custom board

[ozoz05]

Hello.
I'm trying to do spi communication on a custom board with nrf5340 used.
I'm using three threads,
I build it, but if I put it on the board, the board will have a problem.
How can I solve this?

Hello,

[00:00:00.487,915] <err> os: Faulting instruction address (r15/pc): 0x00007011

In VS code can you open an nRF Connect Terminal windows and run arm-zephyr-eabi-addr2line -e .\zephyr.elf 0x00007011 in the project build folder, e.g.:

Also make sure to enable:
https://docs.nordicsemi.com/bundle/ncs-2.8.0/page/kconfig/index.html#CONFIG_THREAD_ANALYZER 

In general you may find this useful:

Is your answer a guide on how to debug??

Type "arm-zephyr-eabi-addr2line -e.\zephyr.elf 0x00007011" in the terminal and it will appear as below image

[Kenneth]

I suspect you are running this from "Powershell" terminal (this will not work), instead use "nRF Connect" terminal, see my screenshot. Alternatively the path to where \zephyr.elf is wrong, try to find in in the build folder.

Kenneth 

[ozoz05]

Is this right??

[Kenneth]

Yes, but the file you are looking for is in build/zephyr/zephyr.elf

Kenneth

[ozoz05]

The results are as shown in the image below.

After that, should I proceed with the next process??

Sounds like a good plan.
