Can't select logging as the coredump backend in Zephyr

[Daniël Schenk]

I'm trying to debug a usage fault in my NCS project using an nRF52833 DK. I can't seem to select the logging backend for coredumps. I have the following lines in my prj.conf:

CONFIG_DEBUG_COREDUMP=y

CONFIG_DEBUG_COREDUMP_BACKEND_LOGGING=y

However, I still need to add a coredump partition to make the build succeed. When the usage fault happens, it still tries to write the coredump to flash, but then a Zephyr assertion fails due to the fact that it wants to take a semaphore from ISR context.

I'm using NCS 1.6.0. What am I doing wrong?

Can you try to get the test zephyr/tests/subsys/debug/coredump up and running? Set CONFIG_RESET_ON_FATAL_ERROR=n (to make it not restart continuously)  and CONFIG_DEBUG_COREDUMP_MEMORY_DUMP_MIN=n (if you want more that the bare minimum content) in the prj.conf. For me it built and run fine, and the dump showed up in the terminal.

You may take a look at the NCS tutorial-->Error handling as well.

Best regards,

Simon

I don't know what was wrong earlier, but it works now, using the same settings I already had.
